摘要
赤柏松含镍基性岩体,是一个产于华北地台北缘东段太古宙地体中的早元古宙阜平期侵位的复式岩体。由变质辉长辉绿岩、中色橄榄辉长苏长岩、暗色橄榄辉长苏长岩、细粒辉长苏长岩与辉长玢岩等侵入岩相构成,赋存有大型硫化铜镍矿床。为了深入探讨岩体的成矿专属性,总结成岩成矿规律等,本文着重对岩体中主要金属矿物进行了穆斯堡尔效应研究。
The Chibansong Ni-bearing basic rockbodies belong to compound deposit in which the large-sized Cu sulphide occurred.Cu-Ni sulphide ores are spotted,disseminated and compactly massive in structttre.The varities of ore minerals are more than twenty,such as pyrite,chalcopyrite,pent- landite etc.In the study of genetic mineralogy and prospecting mineralogy,the author made a study on Mossbauer effect for typomorphic minerals,such as chalcopyrite,pentlandite,pyrrhotite etc.in the typical mineral association, i.e.on the basis of study of mineral chemistry,the Mossbauer parameters and spectrums are measured.The oxidized state,occupation,coordination, and isomorphism of iron are determined through the analysis,providing infor- mation on origin for study of genesis of orestone.So far,it is just the begin- ning in studying the Mossbauer effect of Cu-Ni sulphide mineral in China, and this paper provides some important materials for this study.
