摘　　要：自20世纪70年代以来,地质技术人员在安徽省泗县屏山地区开展了金刚石矿相关地质工作,先后发现原生金刚石及大量的指示矿物,预示该区具有较好的金刚石找矿前景。本文系统总结了研究区与金刚石相关的地质、物探、化探及科研项目成果。以历史成果为基础,通过物探、钻探和化学分析以及电子探针等手段,开展该地区金刚石及指示矿物来源研究工作,结果表明:该区与栏杆地区金刚石具有同源性,指示矿物镁铝榴石、铬铁矿大多来源于金伯利岩或金刚石包体,物理特征与辽宁金伯利岩中的锐钛矿、金红石相似。研究成果具有良好的找矿指示意义,可为下一步找矿提供理论依据。Since the 1970s,extensive geological work has been carried out in the Pingshan Area of Sixian County,Anhui Province,focusing on diamond prospecting.Primary diamonds and numerous indicator minerals have been successively discovered in the region,indicating favorable prospects for diamond exploration.This paper systematically summarized various geological,physical,and chemical exploration and research work related to diamond conducted in the survey area.Based on the previous findings,research on the origin of diamond and indicator minerals in the area was carried out by means of physical exploration,drilling exploration,chemical analysis,and electronic probes,etc.It was found that diamond in study area is homologous with that in the Langan area.The indicator minerals such as pyropegarnet,chromite mostly originates from kimberlite or diamond inclusions,showing similar properties with anatase and rutile in Liaoning kimberlite.The findings have have significant implications for mineral exploration,providing a theoretical foundation for future mineral prospecting.
