| 摘 要： | 陨硫铁(FeS)系各类陨石或月岩的组成之一,它与铁镍合金以及辉石、橄榄石等被视作重要的宇宙矿物,由 Domino Troili 于1766年首先命名。迄今,该矿物主要包含于坠落的陨石残体内部而不时发现于地表(卞德培,1978),对来自天体以及人工合成的 FeS 人们研究得尚较详细,但有关陨硫铁在地壳中的存在状况并不很清楚。最近在攀西岩浆岩中发现的陨硫铁,将对此问题的进一步探讨具有一定实际意义。

| Abstract: | The troilite discovered recently in the layer basic igneous rocks in Panzhihua-Xi-ehang district of Sichuan Province is reported in this paper.The methods such as SEM, EMB, Infrared, XRD, DTA and Sulfur-isotope analysis etc., are adopted for determining this sooalled cosmic mineral.The troilites are intergrown with Hexpyrohotite and have a lamella texture. The grain size is about 0.04-0.001mm, Viker’s hardness=213.84-258.0 kg/mm2 (load 20 g), density (calc)=4.84. It’s composition, crystal structure and physical characters are nearly identical with troilite in the natural meteorite.According to the analysis of related phase diagram and data, the author is assumedthat this mineral was formed under specific tectonic condition--"ancient rift valley"and that the genesis is related to the large-scale vandium-titanie magnetite ore deposits pecular to this region. |
