攀西基性岩中共生的陨硫铁和磁黄铁矿的穆斯堡尔效应研究

使用穆斯堡尔效应研究攀西基性岩中共生的陨硫铁和磁黄铁矿。陨硫铁的分子式为Fe_(1.009)S,晶胞参数a_0=5.96,c_0=11.74,根据Wuensch表示法,可以把它归结为1B,1C型。与陨硫铁共生的磁黄铁矿的分子式为Fe_(0.892)S,属于六方磁黄铁矿。本文确定了共生的陨硫铁和磁黄铁矿的穆斯堡尔参数,它们的谱分别是由一组磁六线谱和三组磁六线谱组成。比较攀西陨硫铁和人工合成陨硫铁及陨石中陨硫铁,可以得出结论,它们之间没有明显差别。

Mossbauer Effect Study of Paragenetic Troilite and Pyrrhotite from Panxi Basic Rock

Mossbauer spectroscopy was used in study paragenetic troilite and pyrrhotite from Panxi basic rock. The formula of troilite is Fe1.009S, and the unit cell parameters are 0=5.96A and c0=11.74A·The troilite studied is refered to LB, 2C type according to Wuensch method. The formula of paragenous pyrrhotite Mossbauer was determined to be Fe0.892S, belonging to hexagonal pyrrhotite. Mossbauer parameters of the paragenetic troilite and pyrrhotite were determined and the spectra of the troilite and pyrrhotite consist of one set of magnetic six lines and three sets of magnetic six lines, respectively. By comparing the troilite from Panxi basic rock with synthetic and meteoric troilite, it can be concluded that there are no significant differences among themo.
