摘要
浙江省遂昌县黄沙腰萤石矿田为首批大地调项目新发现的大型萤石矿田,主要由北东向横坑坪矿脉带上的横坑坪、旺坑大型萤石矿床及内久尖大型萤石矿床组成。矿田内南西段及上定一带,分布大量的中小型矿床(矿点)。矿田控矿构造主要为北东向的控盘断裂及其次级构造,次为北西向断裂。矿田内萤石矿床具垂向分带特征,一般可分为硅质顶盖、头部、中部和尾部,具有相应的围岩蚀变、矿石组构等,据此可判定矿体的剥蚀情况。矿田内萤石质量较好,易采易选,且资源量巨大,可望成为我省又一个萤石矿生产基地。
Huangshayao fluorite ore field, a new discovery, is located in Suichang County , Zhejiang Province,maimly consisting of Heng Keng Ping, Wang Keng and Nei Jiu Jian deposits.The deposits in the field are controlled mainly by NE fault,which controlled the beasin.The deposits are characterised by vertical zoning with silic covers,upper,middle and lower parts,and different wallrock alteration and ore construction and structures.From these the denudation degrees of the deposits can be determined.The field,with good qualility,huge resource and easy to mine,is probally to become another fluorite productive site in Zhejiang Province.
