U/pb and Cr Isotope Study of the Tafassasset
The Tafassasset meteorite which was found the Tenere dessert, Niger, in 2000 and 2001 consists of 26 pieces with a total weight of ~110 kg. The well-preserved meteorite has been studied by several groups [1-4], but until today no consensus on the meteorite's classification was obtained. Reasons for this difficulty are:-texture and mineral abundances vary considerably,-different individual stone...

متن کاملMonazite Dating of Lunar Meteorite Nwa
Introduction. According to their textural and geochemical similarity it was suggested previously that the lunar meteorite NWA 4734 could be launch paired with Antarctic Mare basalts (LAP 02205/224/226/436-03632-04841) themselves possibly paired with NWA 032/470 lunar meteorites despite their different textures (1-5). A possible clue about the pairing issue is evidently their age. Method : After...
متن کاملOxygen Isotopes in Ungrouped Achondrite Nwa 1500 and Comparison to Brachinites
Introduction: North West Africa (NWA) 1500 is an olivine-rich achondrite that is currently classified as ungrouped, based on petrography and oxygen isotope ratios [1-2]. Although some petrographic characteristics of NWA 1500 suggest a relationship to the augitebearing ureilites, it shows a distinct thermal history (equilibration to much lower T) that rules out derivation from the ureilite paren...
