Hi Mckinney, It's been suggested that mesosiderites are the result of a collision of a parent body containing eucrite material and core material. The result is a melting of the material and forming the nearly equal parts of metal to silicate. There is a lot that is not understood yet about this class, but it is thought it could have impacted when the core of a asteroid was still molten with material from the eucrite parent body. Because of this it is possible that some of the material was melted (as in your Vaca sample) into a glassy material. I believe there is an absence of olivine in mesosiderites. McSween book is a good source for chemical makeup of various types of meteorites. --AL Mitterling ----- Original Message ----- From: "mckinney trammell" <[email protected]> To: <[email protected]> Sent: Saturday, October 16, 2010 9:21 AM Subject: [meteorite-list] vaca muerta euc- what is it? > i have several pieces of vaca muerta "eucrite". it is not like any of the other > euc (soft, granite appearance, white). this is very hard , has a "compressed > granular" textue and is homogenous- all one type of mineral. it is glass/ > olivine -like and take a very hi polish. what is this mineral? why is it called > a "Eucrite" since it does not resemble any of the other ones out there? are > there other "eucrites" made of this material? if so got pix? any info or > additional other pix of this or other eucrites made of this material > appreciated. > > > > > ______________________________________________ > Visit the Archives at >http://www.meteoritecentral.com/mailing-list-archives.html > Meteorite-list mailing list > [email protected] > http://six.pairlist.net/mailman/listinfo/meteorite-list > ______________________________________________ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list [email protected] http://six.pairlist.net/mailman/listinfo/meteorite-list
