[meteorite-list] Nanodiamonds

[Lance Wozniak]

Hello Group,   My fascination with meteorites started about 2 years ago when I bought a Gibeon at an astronomy event and then two years later added a nice 40 gram Allende polished end piece as a birthday present. In the last two months I have added six more OC's and pallasites ( El Hammami, Juancheng, Udei Station, NWA 987 L3.8, Brenham and Brahin if it ever arrives from ebay) purchased from members websites and cautious ventures on ebay. I don't know where it will all end but I know I just love owning, looking at, dreaming of and reading about meteorites. I feel I have a responsibility as a small time curator to preserve and know as much about what I have as possible. Norton's recent "Encyclopedia" book is a treasure, and he writes so well it is easy to read even the geochemical details.   I read with keen interest the nanodiamond discoveries in Murchison and reference to it as the most abundant presolar grains in primitive chondites. I am unclear of which primitive chondrites he meant. Just CM's or is CV's, Allende and others possessive of nanodiamonds. Could some one give me a more complete list.   I have a feeling I have the meteorite-collector-gene and hope to see some of you at the next Tucson show or other event.   Thanks,   Lance Wozniak Yuma, AZ
