Hello Tom and List, Here are some selected sulfur values from the literature: 1. Carbonaceous chondrite f a l l s : Mean CI: 5.41 % sulfur* Mean CM: 3.25 % sulfur Mean CO: 2.28 % sulfur Mean CV3: 2.25 % sulfur Renazzo (CR): 1.101 % sulfur * a good match with the abundance in the solar photosphere Hot Desert carbonaceous chondrite f i n d s have lost sulfur. Note the steady decrease in sulfur content between CI and CV3! Refractory elements in CR chondrites resemble those of CI chondrites but there is a noticeable depletion of sulfur. 2. Ordinary chondrites: Zaoyang, H5: 2.49 % sulfur Wuan, H6: 2.21 % sulfur Zaodong, L4: 2.00 % sulfur 3. R-chondrites: Rumuruti dark matrix: 4.14 % sulfur Rumuruti light-colored clast: 3.99 % sulfur Reference: DREIBUS G. et al. (1995) Sulfur and selenium in chondritic meteorites (Meteoritics 30-4, 1995, 439-445). Best regards, Bernd Received on Sat 18 May 2002 04:15:24 PM PDT |
