新疆铁陨石穆斯堡尔效应的研究

A MOSSBAUER EFFECT STUDY OF XINJIANG IRON METEORITE

本文利用穆斯堡尔谱仪,x射线衍射等方法研究了新疆铁陨石。新疆铁陨石主要由体心立方的铁纹石及立方面心的镍纹石组成,此外还有极少量的其他矿物。新疆铁陨石中镍含量分布不均匀,并且铁陨石中的铁都是零价的。

Only chondrite samples were investigated by previous workers using Mossbauer spectrosco-py. However, samples of iron meteorite have not yet examined by Mossbauer spectroscopy in consideration of the difficulties in preparing experimental specimens. In this paper samples of the Xinjiang iron meteorite have been studied by Mossbauer spectroscopy and X-ray diffraction technique. The results show that the main body of the Xinjiang iron meteorite is composed mainly of body-centred cubic kamacite (α-Fe) and face-centred cubic taenite (γ-Fe) with mi-nor amounts of other minerals.
