Garry and Steve, Most excellent posts and information;
Thank you. Forgive me if my questions are poorly based or asked.

Chris,
there are indeed obvious differences. However, typically in leak-off tests
you are applying pressure to a relatively small area, maybe inside a
cylinder 6ft long and 1ft in diameter (you might typically drill 2m of new
formation below the casing shoe prior to the test). The rock is however
Hi Carl-
For the most part, breakup characteristics don't correlate well with
either size or material. I think it's largely a matter of the bulk
properties of the meteoroid- how monolithic versus faulted it is- and
any material can exist on a wide range between those extremes.
For the most p
Hi John-
I don't doubt that there are analogs between the fracturing you describe
at the bottom of a well and what happens with a meteor. However, there
may be some fundamental material differences. The rock at the bottom of
the well is typically very large compared with the area where pressur
Chris,
Working on oil and gas wells it is routine to test the fracture point of
the rock at the bottom of the well after having run and cemented a casing
string (leak off test). You do this by shutting in the well at surface and
pumping incremental volumes of mud into the hole and noting the rise

Hi Chris,
Do you have any references you could point me to for how break-up
scales with size-mass-physical properties etc. of meteoroids. I am
interested in knowing the "sweet-spot" for yielding meteorites on the
ground. In other words, when is a meteoroid too small or too big to
produce significa
A body larger than about a centimeter transfers its kinetic energy to
other forms primarily by compressing the air in front of it as it
descends into the atmosphere. The pressure involved is typically very
large- tens or hundreds of megapascals for meter-class bodies. Once this
ram pressure exc

Dear List,
If there is anyone willing to discuss the how and why meteoroids/asteroids
"detonate" please explain for the list and myself. I am interested learning
more about the electrical/mechanical/physical forces that these bodies undergo
as they reach the earth such as in the latest Russian
