摘要
皖南东至 泾县一带是安徽省主要的金矿 (点 )之一 ,而黄铁矿是本区中金矿床(点 )最主要的载金矿物之一 .论文应用先进的微束分析技术———质子探针分析———对皖南东至 泾县一带金赋存状态进行系统的研究 ,得出初步结论 .结果表明 ,矿体黄铁矿中金的赋存状态以微细粒自然金为主 ,与我国卡林型金矿床中的金的赋存状态一致 ;通过对本区微细浸染金矿带中花山、吕山、柴山、虎龙冲、管岭、白果树等金矿床 (点 )中黄铁矿化学成分和晶体形态等方面标型特征的研究来探讨本区金矿床 (点 )的成矿条件 ,为指出找矿方向 。
The veinlet impregnated gold minerals genetic belt in Dongzhi Jingxian is one of the major gold mineralized belts in Anhui Province,and the pyrite is one of the most important gold loading minerals in the gold deposits.In this study,by means of PIXE,EPMA,the occurrence of gold in pyrite has been fully investigated and the results prove that gold is in the micro grained residence in pyrite.The study of pyrite typomophic peculiarities on both compositions and crystal forms in Huashan,Lushan,Chaishan,Hulongchong,Guanling and Baipuoshuo gold deposits (spots) have resolved some essential problems on gold mineralization conditions as well as the ore prospecting determination and ore prospecting target preparation.
