USA and from Popigayskii (Popigay) impact crater North Siberia Russia. www.meteoritenhaus.de/img/Mascelynite.jpg Best Regards Andi Betreff: Re: [meteorite-list] Questions Hi Greg and List! #2: Yes! Here is a list of some minerals, which were found in meteorites, but not in terrestrial rocks so far (to my knowledge). If someone has additional information or correction please post them.: - Barringerite (Fe, Ni)2P only in iron meteorites - Carlsbergite CrN only in iron meteorites - Cliftonite C (a special sort of graphite) not known in terrestrial rocks in this form - Daubr?elithe FeCr2S4 in iron meteorites - Djerfisherite K3(Cu, Na) (Fe, Ni)12S14 only in E-type chondrites - Kamacite - Taenite - Plessite - Farringtonite Mg3(PO4)2 in pallasites - Maskelynite Na-Ca-Al-Silicate - Niningerite MgS E-type in chondrites - Oldhamite CaS (not known in terrestrial rocks; but will be generated by some sorts of smelting processes) - Perryite (Ni, Fe)5(Si, P)2 in iron meteorites - Sinoite Si2N2O in E-type chondrites Information was taken from: von R?TYI, A., Aumann, G.: Meteorite - Boten aus dem Weltall, Naturkunde-Museum Coburg, 1996 It's possible, that some of these minerals have been already discovered in terrestrial rocks since 1996. Hope that helps a little! Best wishes Ingo Betreff: [meteorite-list] Questions Hello List: ? I have two questions: 1.?????? Has any rock formed on Earth been found containing Chondrules in it? If so, what kind of rock and where was it found? 2.?????? Are there any minerals found in Meteorites that are NOT found (or formed) on earth. Much Thanks, Greg S. ________________________________________ Need Mail bonding? Go to the Yahoo! Mail Q&A for great tips from Yahoo! Answers users. Received on Mon 21 May 2007 05:04:03 AM PDT |
