Mössbauer studies of iron sulphides present in ordinary chondrites type LL

Abstracts

EN

Mössbauer measurements of three ordinary chondrites type LL were performed at room temperature. Values of spectral areas (SA) connected with troilite were different for investigated meteorites: for Oued el Hadjar – 4.8%, for Bjurböle – 10.6%, for NWA 8590 – 14.9%. Mössbauer spectra were fitted with the use of Recoil program. In all samples values of internal magnetic field and theta angle for subspectrum of troilite were the same: H = 31 T, theta=62°. In the sample of Bjurböle meteorite the signal from pyrrhotite was also noticed (SA = 1.7%, H = 25 T, theta = 33°). For meteorite NWA 8590 two subspectra of pyrrhotite were fitted with following parameters: for pyrrhotite I (SA = 1.1%, H = 27 T, theta= 41°), for pyrrhotite II (SA = 0.7%, H = 22 T, theta = 33°). It is easy to notice that the presence of pyrrhotite is correlated with higher amount of troilite in the samples of ordinary chondrites type LL.
