Hi List, Ingo, Greg,

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

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.
