湘中地区硅化岩研究

Study on the Silicified Rqcks in Central Hunan

湘中地区硅化岩，产出层位多，原岩组成多样，与仰矿化关系密切。空间上，锑矿化受早期硅化（岩）控制；时间上，锑矿化主要伴随早期硅化岩中的晚期硅化产生；成因上，硅化（岩）与锑矿化之间不存在必然联系，二者之内在联系，仅在于碎裂硅化岩为矿质堆积提供了良好的空间。

The silicified rocks in central Hunan,occurred in many stratigraphic horizons,originated from rocks varyingin composition,are closely related to the antimony mineralization. The antimony nunernlization is spatially controlled bv the silicified rocks formed in the early periodi and temporally by those formed in the late stage of the early period.No inevitable genetical coiinection between silicification and antimony rniheralization be proved.Their internal connection may lie in that the fractured silicified rocks prov1de good space for mineral ac-cumulation.
