摘　　要：青罗山钨矿位于江南隆起带北东端,是最近新发现的一处中型矽卡岩型钨矿床。其矿体主要产于休宁组上段上部与侵入岩体花岗闪长岩的外接触带内,矿体产状与地层产状基本一致,矿体形态简单,矿体形态受地层界线限制。主要的矿石类型为矽卡岩型钨矿石、矽卡岩化砂岩-粉砂岩型钨矿石,矿化分布相对稳定。本文通过野外地质调查和室内综合研究系统的总结了青罗山钨矿床的区域地质背景、矿区地质特征、矿床地质特征等,认为矿床成因类型为矽卡岩型白钨矿床。通过与其邻近的上金山钨钼矿床对比研究,发现两者之间存在有一定的分带性差异。研究可为皖南地区寻找该类型矿床提供启发与借鉴。Qingluoshan tungsten deposit is located at the northeast end of Jiangnan uplift belt. It is a newly discovered medium-size skarn type tungsten deposit. The Qingluoshan tungsten ore body is mainly distributed in the calcareous strata of the upper member of the Xiuning formation, and basically consistent with that of the stratum. The main ore types are skarn tungsten ores, skarnized sandstone-siltstone tungsten ores, and the mineralization is relatively stable. Based on field geological survey and comprehensive study, this paper systematically summarizes the regional geological background, mining area and geological features of the Qingluoshan tungsten mine. It is preliminarily considered that the origin of the skarn-type scheelite deposit formed by complex mineralization between magma, surrounding rock and ore-bearing hydrothermal fluid. In addition, through the comparison with the adjacent Shangjinshan tungsten-molybdenum deposit. It is found that there is a zonation between the two deposits.This study hopes to provide inspiration and reference for the search for this type of deposit in southern Anhui.
