But no offense to you Bernd, I have always felt thin section photos (of any rock) were meaniningless unless there was a description of the section" Hello Matt and List, Well, I got this NWA 2999 angrite thin section only recently so I haven't had enough time yet to study it thoroughly but here is what I have already seen and written to David Weir about it: 1. the vivid bluish pink crystals are zoned, calcic olivines; 2. the dazzling white crystals are anorthites; 3. the light and medium brown, yellowish brown crystals are fassaitic pyroxenes; 4. the upper half of the TS is dominated by vivid blue diopside crystals; 5. Numerous isotropic spinel crystals appear black with crossed polars. Best regards, Bernd Received on Fri 27 Jan 2006 12:58:25 PM PST |
