内容記述 |
Thermal release of organic compounds from three CI chondrites (Belgica (B)-7904,Yamato (Y)-82162,and Y-86720) and three CM chondrites (Y-74662,Y-791198,and Y-793321) was examined by DTA/TG-MS analysis. For identification of the compounds released, Y-791198 was also examined by DTA/TG-GC/MS analysis. The relative amounts of organic compounds released from these chondrites are, Y-74662≃Y-791198>Y-82162>Y-793321≃B-7094>Y-86720 The compounds released are aliphatic and aromatic hydrocarbons and N-, S-, and O-containing compounds. Of these, benzene and thiophene are the most abundant. Release patterns of some representative compounds were obtained along a programmed temperature profile from room temperature to 800℃. These patterns fall under one of two kinds; in one the release starts around 250℃ and continues to 700℃, and in the other release starts at 100℃ or 150℃ and ends at 300℃. The kinds and amounts of the organic compounds released are roughly related to the extent of the alteration and/or metamorphism of the chondrites as determined by mineralogical and petrographic studies. |
