摘要
皖南郭村钒矿处于扬子陆块东南缘江南古隆起内的历口构造带和太平褶断带的交界部位,位于历口-羊栈岭大背斜的北翼。含矿地层为早寒武世荷塘组的一套浅变质黑色炭质板岩,可对比划分出4个矿层。矿体主要受沉积变质作用控制,层控性明显,成因类型为沉积变质型石煤钒矿床,形成于温暖潮湿的浅海相还原环境。含有磷结核和钙硅结核的黑色岩系是本区寻找钒矿的重要标志,通过郭村钒矿床成矿地质特征和矿床成因的研究,对于皖南地区寻找同类矿产具有积极的指导意义。
The Guocun navajoite deposit is located at special borderland of Likou tectonic zone and Taiping fault-fold belt in Jiangnan paleouplift in south-east margin Yangtze landmass,and it belongs to southern part of Likou-Yangzhanling anticline.The stratum with navajoite is black rock series-carbonaceous slate by metamorphosed slightly,which is developed in Hetang group at lower Cambrian.Through the contrast study,the navajoite deposit was divided into four ore layers such as V1,V2,V3 and V4.The deposit genesis type is stone coal navajoite deposit controlled by sedimentation and metamorphism,which were formed at shallow sea reducing environment with warm and humidity climate.A significant symbol layer of finding navajoite deposit is black rock series with phosphorus nodule and cal-silicon nodule.On the basis of a detailed study on geologic characteristic,ore characteristics and deposit formation cause,the prospecting indicators can be summarized to provide practical experience and theory evidence for navajoite exploration in south Anhui.
