陕西镇旬地区金矿黄铁矿的标型特征与初步总结及其找矿意义

TYPOMORPHIC CHARACTERISTICS OF PYRITE IN GOLD ORE IN THE ZHEN'AN-XUNYANG AREA AND THE SIGNIFICANCE IN ORE PROSPECTING

陕西镇（安）旬（阳）地区主要分布着微细浸染型、钠长石碳酸盐角砾岩型和石英脉型金矿。黄铁矿是区内金矿中分布最广、最重要的载金矿物。通过对诸金矿中黄铁矿的形态、主成分、微量元素、晶体结构、红外吸收光谱及热电性标型特征的总结和研究表明，黄铁矿标型特征的明显差异反映了其成因的不同，其形态和热电性标型特征是预测成矿远景地段的有效方法之一。

There are fine disseminated, albite-carbonate breccia and quartz vein types of gold deposits mainly occurring in Zhen’an - Xunyang area in Shaanxi, in which pyrite, most distributed in those gold ores, is the most important gold-bearing mineral. Analysis and researches on the pattern , dominant element, microelement, crystal texture, infrared absorption spectroscopy and pyroelectricity typomorphic characteristic of the gold-bearing pyrite indicated that the appearing difference of the pyritic typomorphic features can reflect variation of ore genesis and the patterns, and the peryelectric typomorphic characteristics can used as one of efficient methods on prediction of metallogenic potential areas.
