Hello Steve, Alan and List, Back from watching the Mundrabilla episode of Steve and Geoff! Great episode! But let's now move on to Steve's question. Steve inquired:
"...do carbonaceous chondrites ever have impact melt zones in them?" According to my database queries, impact melt (clasts) have been found in Kaidun (CR2)* and in NWA 1814 (CB3a). *ZOLENSKY M. et al. (2001) Kaidun: A smorgasbord of new asteroid samples (MAPS 36-9, 2001, A233). Shock melts have been found in QUE 94411 (CBb) and HaH 237 (CBb)*: *MEIBOM A. et al. (2000) Metal/sulfide-ferrous silicate shock melts in QUE 94411 and HaH 237: Remains of the missing matrix? (abs. Lunar Planet. Sci. 31, abstract #1420, Lunar and Planetary Institute, Houston, Texas, USA, CD-ROM). ... and about QUE 99038 (CM2), Kathleen McBride wrote: "This carbonaceous chondrite has a dark gray to blackish crust, but appears to be a m e l t e d g l o b of chondrules spread over the entire exterior of the rock" (AMN 24-1, Feb 2001, p. 12).
