重庆市含煤地层叙永式硫铁矿含矿特征及控矿建造研究

Orebaring Feature and Ore-controlling Formation of Late Palaeozoic Pyrite of Chongqing Coal-bearing layer

重庆市硫铁矿主要为沉积型矿床。本文通过对重庆市域内上扬子陆块晚古生代二叠系含煤地层内中叙永式硫铁矿的成矿背景特征、赋存特征、含矿特征的分析,阐明了重庆市叙永式硫铁矿的成矿建造、沉积环境,并对硫铁矿成矿地层、区域构造及含矿建造对成矿的控制作用进行了分析、探讨。

The pyrite is mainly sedimcatary stlye in Chongqing. Based on the analysis of metallogenic settings,the feature of geology and ore-bearing,this article elucidates the metallogenet ore-bearing and sedimentary environment about pyritic deposits that located in late permian in upper-Yangtze massif in admnistrative region of Chongqing,discusses the eontroling role of metallogenetic stratum, regional structur to ore-bearing foramation.
