[meteorite-list] RE: Meteorites ~ Deep-Freeze on Mars

[Pete Pete]

Hello, Al,

I've read both links - Thank you.
The way I understand the paper is that the depths of origin for the martian 
meteorites have been determined, but not the location(s) on the planet as of 
then:

>>"Michael Lipschutz, professor of chemistry, analyzed the trace element 
>>content of the 12 meteorites that are known to have originated from Mars 
>>and found that the rocky fragments came from six different regions below 
>>the surface of the planet."<<

and

>>"Further studies may help pinpoint the location of each of the regions, 
>>and could shed light on Mars' geological history, Lipschutz says."<<

The paper is a bit dated (1998), but your lead to Ron Baalke's link;

http://www2.jpl.nasa.gov/snc/index.html

has at least a few recent articles that identify specific surface sources...
This is what I was after.

Much appreciated!

Pete

Hi Pete,


In regards to finding Martian locations related to Martian Meteorites,
Actually on August 4th 1998 such a report was made by Dr. Lipschultz from 
Purdue University. I'll just give the link but give a brief description 
here.

Six areas have been determined (with a good degree of certainty) that are 
probable source regions that may have delivered Meteorites from Mars. This 
was based on 15 volatile trace elements. I might add that the suspect areas 
all have craters that could be the launch impact area of the Martian 
Meteorites we hold in our collections.
