Re: [meteorite-list] Meteorite Picture of the Day: Alais?
Thanks for a nice picture. But, the texture of this meteorite looks not CI1 but CM or CR. So, the meteorite may be not Alais (CI1) but Al Rais (CR2-an)? But, I don't know whether or not the Paris museum houses a collection of Al Rais.

Webb sterling_k_w...@sbcglobal.net To: countde...@earthlink.net; meteorite-list@meteoritecentral.com Sent: Thursday, September 30, 2010 11:27 AM Subject: Re: [meteorite-list] Habital Planet Discovery Announcement Hi, Count, List, Also reported here: http://www.space.com/scienceastronomy/earth-like-exoplanet-possibly-habitable-100929.html The finder is excessively enthusiastic about the chances of life. There are problems with a three-earth-mass. It will not be like a Big Earth. It's more complicated than that. (The Yahoo article has the mass wrong, BTW.) If you start with the same recipe mix of ingredients as the Earth and just made a bigger batch of planet, is it just the same as the Earth, only more so? Nope, more of the same is definitely not the same. If the Earth were bigger, the volume of water would increase faster than the increase in surface area, so the oceans would be deeper. Because of the deeper oceans and the greater gravity, the pressures at the bottoms of those oceans would be much higher. Continents and their mountains would be much lower, because the temperatures in the crust would increase faster with depth, until the fluid point would be reached in the crust instead of the mantle like it is on our Earth. Mountains can only pile up until the pressures under them are about 3000 to 3500 atmospheres, and that zone would be reached at shallower and shallower depths on a bigger and bigger Earth. Since the solid crust of a larger Earth would be much thinner, heat transfer to the surface much faster, vulcanism much livelier, plate tectonics much zippier. This Earth has a diameter 1.40 times that of our Earth: 11,200 miles across. It would have twice the surface area, 2.75 times the volume, and 3 times the mass (compressibility squishes). It's surface gravity would be 51% greater. If the planet is four Earth masses, its diameter would be 1.58 times the Earth's without accounting for compressibility and about 1.50 to 1.53 Earth radii squished. Its surface gravity would be 73% greater than the Earth's, in that case. But I'll continue to calculate based on three E-masses... Because it would have 3 times the water but only two times the surface, the average ocean depth would be about 4500 meters! The pressure at the depths of these oceans would be about 9000 atmospheres. The highest mountains possible would be about 4000 meters (calculating from the median diameter), so if you were the greatest mountain climber on this Super Earth, standing on the top of Super Earth's highest mountain, you would still have 500 meters of water above you! On our Earth, the crust is about 30 kilometers thick, but the lithosphere (rocks that stay stiff and not slushy and slippy) is about 75 kilometers, so the Earth's lithosphere contains all the crust and the top part of the mantle. The crust of the Super Earth would be about 60 km thick, but the lithosphere would only be about 40 kilometers thick. This means that it would be very difficult to sink pieces of crust (subduction) and equally difficult to bring deep basalt magmas to the surface. On the other hand, the Super Earth's silicate crust would be recylced very rapidly with lots of local vulcanism and lots of hotspots and have a very similar composition everywhere. The only weathering that would be possible would be chemical, because all the volitiles are released into the oceans rather than the atmosphere. So a bigger Earth is not just a bigger Earth. Knowing that somebody will ask how much bigger a bigger Earth has to be before there's no land at all, just oceans, the answer is: somewhere between 2-1/2 and 3 Earth masses is the point where the median ocean depths equal the height of the highest possible mountain. Whoops! No continents. This Super Earth is a WaterWorld! Possibly very few islands. That's serious. It means No Surfing, because there's no land for the waves to break on. It's almost certain that it would have more water than our Earth, because the star is metall-poor (see below). A red dwarf is a main sequence star: once a dwarf, always a dwarf. It's just a low-mass star with a longer lifetime (25 billion years?) than our Sun (10 billion years?). At a third of a solar mass, it's got a respectable little heliosphere and all the usual solar (or stellar) apparatus, just less extensive than a G0 dwarf star like us. But it doesn't have as big a system to fend outside radiation away from. In general, M-class star systems seem to be quiet places. Some theorists regard smaller stars as safer places (sort of like being a stellar mouse; just keep quiet and no one will notice you). M-class dwarfs are very, very common and often very old, but their age is often hard to determine. [Their stellar atmosphere is full of diatomic molecules and their spectra are, like, scrambled eggs!] I looked

This post is directed at the silent newbie or beginner lurkers who are sorting through this List and trying to find their way around the world of collecting meteorites. Many new collectors often want one of each type of meteorite. Many veteran collectors abandon this pursuit because the task is quite daunting. So when you hear talk about type collecting, or building a type collection, what exactly does that mean? I hope the following brief article will answer those questions, or at least point the reader in the right general direction. Note, I gleaned much of this type information from David Weir's authoritative website Meteorite Studies and from the Meteoritical Bulletin. I do not claim that this list is 100% complete or without error, so if the reader spots an error or omission, please reply and correct it. - The Perils of Type Collecting I started out collecting meteorites with a small sample of NWA 4293 - an ordinary high iron chondrite of the H6 type. It was about the size of a dog-food kibble and it looked like one. But I was instantly hooked, and I wanted to have one each of the different types of meteorite. This is known as type collecting or building a type collection. The danger of type collecting (besides the damage to one's checking account) is that the various petrologic types are subdivided into various grades according to metamorphism. For example, take the H chondrite group that my NWA 4293 sample belonged to. There are H3 chondrites, H4 chondrites, H5 chondrites, and H6 chondrites. Did I really need one each of these subtypes? Well, it depends on how deep a collector wants to go into the rabbit hole. There are distinct differences between the various H types. The number attached to each is more than just a simple weathering grade or shock grade. It represents a progession in the H-chondrite family from least altered to most altered. H3 chondrites are loaded with chondrules, H4 have some chondrules, H5 has few chondrules, and H6 has virtually no visible chondrules. A new grade of H7 has been added as well. So, a collector could simply have a single Hx chondrite and say that the H-chondrites are represented. Or, the collector could have one each of the different subtypes from 3 to 7. Another peril is the changing of nomenclature. For example, the K-subgroup of carbonaceous chondrites was only recognized and designated in 1990. Up until then, Karoonda was considered a CV4 meteorite of the Vigarano family. Now Karoonda is recognized as distinctly different type of carbonaceous chondrite, so it was made into it's own group. Now we have CK4, CK5, and CK6 meteorites - all represent a progression in metamorphism and have visible (and chemical) differences from other grades. There are standout members of each subgroup, so where does one draw the line? Should the collector acquire a sample of Karoonda and be done with it? Or should the collector go out and track down CK4, CK5 and CK6 meteorites? Again, it depends on how extensive and exhaustive a collector wants to be with their type collection. Budget will also play a role as well, because an exhaustive type collection is a daunting project. Lastly, one must consider the ungrouped meteorites. These are oddball meteorites that do not neatly fit into the pre-existing meteorite types. There are ungrouped chondrites, ungrouped achondrites, and ungrouped irons. No type collection can overlook these meteorites because some of them are types

Morphologies, textures, and chemical compositions of constituent particles reveal that they are high-temperature melting products and are of extraterrestrial origin. Because similar layers were found approximately 2000 km east of Dome Fuji, at EPICA (European Project for Ice Coring in Antarctica)-Dome C, particles must have rained down over a wide area 434 and 481 ka.
