### Understanding Patterns in Nature: The Third Way

Let's start with something familiar: the striking stripes on a zebra. These
patterns, along with many others in nature, arise through fascinating
processes. Traditionally, explanations include intelligent design and
natural selection, but there's a compelling third way—far-from-equilibrium
(FFE) dynamics.

### Patterns and Symmetry Breaking

Patterns, like zebra stripes, often display symmetries, but they emerge
through symmetry breaking. This means that a uniform, undifferentiated
field transitions into a structured form. For example, zebra stripes form
from a uniform distribution of skin cells that differentiate into distinct
black and white patterns.

### FFE Dynamics: A New Perspective

FFE dynamics explains how patterns emerge when systems are driven away from
equilibrium by external forces. This approach is applicable across various
fields, including biology, physics, and meteorology. Let's break it down
with some examples, including the volcanic dikes you're curious about.

1. **Turing Patterns in Biology:**
   - Alan Turing proposed that chemical reactions and diffusion can lead to
stable patterns like zebra stripes. These patterns arise from a uniform
chemical distribution breaking into distinct structures.

2. **Volcanic Rifts and Dikes:**
   - Magma from deep within the Earth rises through cracks in the crust,
forming volcanic dikes—linear features that break the symmetry of the
surrounding rock. Now, let's address your specific question about why these
dikes are linear.

### Explaining Volcanic Dikes

Imagine the Earth's crust as a series of horizontal layers. When magma
(molten rock) pushes upwards, it seeks the path of least resistance,
exploiting pre-existing weaknesses and fractures. Here's why these
fractures often form straight lines:

- **Micro Cracks and Stress Fields:**
   - When stress is applied to a solid material, like pushing on a layer of
ice, it doesn't distribute evenly. Instead, stress concentrates at points
of weakness, causing micro cracks to form. If the stress continues, these
cracks propagate.
   - The first two breaks align because the stress is highest at the tips
of existing cracks. When a new crack forms, it follows the direction of
least resistance—often in a straight line with the previous cracks.

- **Order Parameters and Phase Transitions:**
   - In FFE dynamics, variables like stress (order parameters) determine
the system's macroscopic state. As the stress increases, the system
undergoes a phase transition, breaking symmetry to form an ordered
structure (a linear dike).

### Addressing Your Ice Example

Consider pressing down on a thin layer of ice with your hand. The initial
cracks form where the stress is highest. As you continue pressing, each new
crack propagates from the tips of the existing cracks, often forming a
straight line. This happens because the stress field is now guiding the
cracks to follow the path of least resistance, maintaining the linear
alignment.

### Encouragement to Study FFE Dynamics

Studying FFE dynamics reveals the profound and elegant ways nature
organizes itself. It shows that complex patterns can arise from simple
rules without needing an intelligent designer, offering alternative
explanations for patterns in biology and behavior that were traditionally
attributed to natural selection.

### Conclusion

FFE dynamics provides a powerful framework for understanding the rich
tapestry of patterns in nature. It bridges the gap between simple physical
laws and the intricate beauty we observe. As you delve into this field,
consider exploring this third way to uncover the mysteries of natural
patterns and the processes that drive their formation.

Re: [FRIAM] "Weather line" on 14

[steve smith]

And another regional example of interest:

   https://spanishpeakscountry.com/the-great-dikes/

The text suggests "igneous intrusions into sandstone" and "sandstone 
eroded away to expose the igneous intrusions".


I'm familiar with igneous "plugs" such as my nearby Black Mesa and the 
famous Devils Tower in WY.  I believe the characteristic "basaltic 
piles" I see in other formations in my area imply 'igneous intrusion" 
rather than "igneous flow" reflecting the way such things cool.


The Spanish peaks dikes are radial from the peaks reminiscent of a 
"Mordor-like landscape" with cracks radiating from the mountain and lava 
rising up out of it.


Thanks to the other curious-obsessives here to help push me from decades 
of "wondering" to feeling at least a little more informed about the 
geology (and weather).

Re: [FRIAM] "Weather line" on 14

[Nicholas Thompson]

...he lives in the Gallisteo Basin.

I am beginning to think that nature does not abhor straight lines quite as
much as I first thought.  The San Andreas Fault is pretty straight for a
thousand miles. Cloud streets.Given the right conditions of sheer,
etc., thunderstorms can form straight lines.  And, of course, sediment
boundaries and coastlines facing  a flow, as in  FL.  Still, I think it
makes sense not to take them for granted.

If anybody has the time,  I would love to have Eric's physical explanation
put into language that is more friendly to former defrocked former english
majors.  I get the intrusion bit.  That's fine.  Where I stumble is where I
seem to detect an assumption that the forces them selves that are exerted
from below  are linear.  Standing on my huge pile of ignorance, here, I
would assume that they are bubbles and I cannot see how a bubble pushing up
on a sedimentary layer would exert a straightline force on it.  Thinking in
micro cracks for a sedond: the first two breaks form a straight line for
sure.  But let's say I am pressing down on a thin layer of ice with the
palm of my hand.  What, in DFEM terms is the reason that the third break
should be in line with the other two.

This is where Doug Roberts arises from his grave and dope slaps me with his
mighty paws!

Thanks for your patience, all.

Re: [FRIAM] "Weather line" on 14

[Santafe]

A few km or even tens of km does not seem long to me on geological scales.

If we have slowly formed crustal rock, it could be fairly uniform.  Then if 
there is a bending stress on large scales from upwelling, the least-disruption 
fracture would be a long straightish crack along the the line perpendicular to 
the bending moment.  Also, the material that goes into that crack is presumably 
pretty liquid.  So while it is okay to call it “rock pressing up”, I think the 
image of liquid squeezing into a fracture, shoving apart the sides, and putting 
maximal stress on the apex which extends the fracture further, is more like the 
picture.

And in whatever page somebody sent, they say the fracture that forms the 
Galisteo dike shows evidence of having formed in that way, by chaining one 
extension onto another, along the stress line where the faces are being pushed 
apart.

When this happens in the sea bottom, seismometers can listen to what sounds 
like a zipping sound, as the crack from some new upwelling extends and extends. 
 I forget if it was a review by Karen von Damm or by Deb Kelley in which I 
learned that.  They have some name for it, which I am forgetting.

Of course, continental crustal rock is not the same as seabed basalts (which 
are probably much more uniform), but even so, these are geologically fairly 
small features we are talking about.

Re: [FRIAM] "Weather line" on 14

[Barry MacKichan]

Several times on the Thuram Zoom call, I asked “Do you mean that 
volcanic dike?” but I always seemed to say it just as someone else 
started up.


I have two memories about it.

1. The president of SAR conjured up the image of 3,000 Comanches coming 
through the gap (Comanche Gap) as they came to Santa Fe in the 1770s to 
agree to the truce with New Mexico — the truce that I believe enabled 
the Spanish to hang on for the next 50 years in NM. The image has stuck 
with me.


2. I thought it would be a great place to find petroglyphs, and indeed 
it is. The density of the “No trespassing” signs along the road 
increases as the square of the inverse of the distance from the point 
where the road crosses the dike. They make it clear exactly where you 
should not trespass.

Basic formation given this description (chatGPT):


The Galisteo Dike is a geological formation characterized by its
composition and physical properties, indicating its formation through
volcanic activity. Here’s a detailed interpretation of its formation 
based

on the description provided:

1. **Composition Analysis**: The Galisteo Dike consists of 
micro-monzonite,
a fine-grained igneous rock. It contains a mixture of minerals 
including

plagioclase, potassium feldspar, titan-augite, titaniferous biotite,
apatite, and opaque grains in a glass groundmass. This mineral 
composition
suggests that the dike formed from magma that cooled relatively 
quickly,

preventing the formation of large crystals.

2. **Physical Description**: The dike appears as a dark gray, 
fine-grained
rock with a salt and pepper texture. It weathers to dark brown or 
grayish

brown and forms a wall-like rampart. This implies that the dike is
resistant to weathering and erosion, standing out in the landscape as 
a

prominent feature.

3. **Structural Features**: The dike is described as comprising many 
right
echelon overlapping segments varying in length from 200 to 1200 feet 
and up
to 18 feet thick. This pattern of overlapping segments indicates that 
the
magma was injected into pre-existing fractures in the surrounding 
rock,

likely under significant pressure, causing the fractures to open and
propagate in an en echelon pattern.

4. **Geological Age**: The dike is dated to 26.55 million years ago,
placing its formation in the Oligocene epoch. This was a time of
significant tectonic activity in many parts of the world, often 
associated

with volcanic and plutonic intrusions.

### Formation Process
1. **Magma Intrusion**: The formation of the Galisteo Dike began with 
the

intrusion of magma into fractures in the Earth's crust. The magma,
originating from deeper within the mantle, was rich in the minerals
described and had a high temperature, allowing it to flow and 
penetrate the

fractures.

2. **Cooling and Crystallization**: As the magma moved upward through 
the

fractures, it began to cool and solidify. The rapid cooling near the
surface resulted in the fine-grained texture of the rock, with 
minerals

crystallizing quickly in the groundmass of glass.

3. **Fracture Propagation**: The injection of magma caused the 
fractures to

propagate, leading to the characteristic right echelon overlapping
segments. This suggests that the fractures did not open uniformly but
rather stepped along the strike, with each segment forming as a 
discrete

intrusion event.

4. **Weathering and Erosion**: Over millions of years, the surrounding 
rock

may have eroded away, leaving the more resistant dike exposed as a
wall-like structure. The weathering of the dike itself results in the
observed dark brown or grayish brown coloration.

In summary, the Galisteo Dike was formed by the intrusion of magma 
into

fractures in the crust, followed by rapid cooling and crystallization,
resulting in a fine-grained igneous rock with distinct mineral 
composition
and structural features indicative of significant volcanic activity 
during

the Oligocene epoch.

I wouldn't say something you said was absurd.  I remember that straight

Re: [FRIAM] "Weather line" on 14

[Stephen Guerin]

Research last night on historical geologic maps got the name of that as the
"Galisteo Dike". composition and description in attachment. There is one
further with as well. Also known as the Creston or Comanche Gap

https://galisteo.nmarchaeology.org/sites/creston.html


Basic formation given this description (chatGPT):


The Galisteo Dike is a geological formation characterized by its
composition and physical properties, indicating its formation through
volcanic activity. Here’s a detailed interpretation of its formation based
on the description provided:

1. **Composition Analysis**: The Galisteo Dike consists of micro-monzonite,
a fine-grained igneous rock. It contains a mixture of minerals including
plagioclase, potassium feldspar, titan-augite, titaniferous biotite,
apatite, and opaque grains in a glass groundmass. This mineral composition
suggests that the dike formed from magma that cooled relatively quickly,
preventing the formation of large crystals.

2. **Physical Description**: The dike appears as a dark gray, fine-grained
rock with a salt and pepper texture. It weathers to dark brown or grayish
brown and forms a wall-like rampart. This implies that the dike is
resistant to weathering and erosion, standing out in the landscape as a
prominent feature.

3. **Structural Features**: The dike is described as comprising many right
echelon overlapping segments varying in length from 200 to 1200 feet and up
to 18 feet thick. This pattern of overlapping segments indicates that the
magma was injected into pre-existing fractures in the surrounding rock,
likely under significant pressure, causing the fractures to open and
propagate in an en echelon pattern.

4. **Geological Age**: The dike is dated to 26.55 million years ago,
placing its formation in the Oligocene epoch. This was a time of
significant tectonic activity in many parts of the world, often associated
with volcanic and plutonic intrusions.

### Formation Process
1. **Magma Intrusion**: The formation of the Galisteo Dike began with the
intrusion of magma into fractures in the Earth's crust. The magma,
originating from deeper within the mantle, was rich in the minerals
described and had a high temperature, allowing it to flow and penetrate the
fractures.

2. **Cooling and Crystallization**: As the magma moved upward through the
fractures, it began to cool and solidify. The rapid cooling near the
surface resulted in the fine-grained texture of the rock, with minerals
crystallizing quickly in the groundmass of glass.

3. **Fracture Propagation**: The injection of magma caused the fractures to
propagate, leading to the characteristic right echelon overlapping
segments. This suggests that the fractures did not open uniformly but
rather stepped along the strike, with each segment forming as a discrete
intrusion event.

4. **Weathering and Erosion**: Over millions of years, the surrounding rock
may have eroded away, leaving the more resistant dike exposed as a
wall-like structure. The weathering of the dike itself results in the
observed dark brown or grayish brown coloration.

In summary, the Galisteo Dike was formed by the intrusion of magma into
fractures in the crust, followed by rapid cooling and crystallization,
resulting in a fine-grained igneous rock with distinct mineral composition
and structural features indicative of significant volcanic activity during
the Oligocene epoch.

Re: [FRIAM] "Weather line" on 14

[Nicholas Thompson]

Dear Stephen,

Thank you for prompting me to respond to this inquiry.  I was having some
trouble getting the image to behave on my computer, and so was reluctant to
wade in.

 Indeed, just as nature abhors vacuums, she abhors straight lines, and so
any line as straight as this one requires a special explanation.  To me,
that the line points southwestward toward the radar site NW of ABQ suggests
a radar artifact, perhaps the shadow or some distant hill.  As we watched
the animated radar image, we could see a persistent weakness in the radar
echo along that line, even as the clouds crossed it.

Speaking of abhorrent straight lines, during our conversation with Frank,
we spent quite a lot of time discussing another line, a berm of sand that
runs across the Galisteo Basin in roughly the same orientation, perhaps 50'
high?.  I had noticed this feature on topo maps and always assumed it was
an old railway embankment.  Frank, who knows the area well, thought that
idea was absurd.  So, we were left with the puzzle of a highly linear
geological formation several miles long.

Could it be that this geological straight line accounts for the straight
line cloud formation that Mr. Kadlubek  sees? As the dry line breaks down
in anticipation of the SW Monsoon, moist air does indeed move northward,
following the river valleys up from TX.   AT some point, it will be raised
enough that its moisture is condensed leading to the release of latent heat
and the further development of clouds.  If the structure that raises it is
a straight line, then the clouds themselves will be arranged in a straight
line.  We can see this effect often along linear coast lines as a sea
breeze front topped by (usually) fair weather cumulus.  However, given all
the dramatic topography in the area, it's hard for me to imagine that this
low lying feature would be determining very often.

I, too, live for the weather.  I don't live for Face Book, however.  So if
you have any way to put in touch with Mr. Kadlubek, he and I could perhaps
have coffee when I get back to Santa Fe in the fall.

Yours faithfully,

Here's the video where the weather line is apparent near the Galisteo
