Total Carbon and Sulfur Abundances in Antarctic Meteorites

P(論文) Total carbon and sulfur abundances have been measured in five Antarctic meteorites. Two C2 carbonaceous chondrites Yamato-74662 and ALHA 77306 have sulfur abundances (3.490±0.040% and 3.863±0.050% respectively) similar to other C2 chondrites but their carbon abundances (1.514±0.050% and 1.324±...

Description
Summary:P(論文) Total carbon and sulfur abundances have been measured in five Antarctic meteorites. Two C2 carbonaceous chondrites Yamato-74662 and ALHA 77306 have sulfur abundances (3.490±0.040% and 3.863±0.050% respectively) similar to other C2 chondrites but their carbon abundances (1.514±0.050% and 1.324±0.040% respectively) are lower than previously measured C2 chondrites. The decreased carbon abundances may reflect the effects of weathering in cold environments. Carbon and sulfur abundances for one C4 carbonaceous chondrite, one E4 enstatite chondrite and one ureilite are similar to values reported previously for meteorites of the same petrologic grades. departmental bulletin paper
