摘　　要：天目山岩体形成于华北地台南缘与秦岭褶皱系的衔接处,位于我国著名的东秦岭—大别山钼成矿带东段。通过对该区岩性参数及成岩成矿地质条件的综合研究,作者认为其该区钼矿的形成与燕山晚期侵入的天目山超单元花岗岩体有直接的成生因联系,分析了该区岩体特征,异常元素分布特征,成矿物质来源,以期为矿山评价或对寻找同类矿床提供依据。Tianmushan pluton is formed at the junction of the south margin of North China Platform and Qinling Fold system,and is located in the eastern part of the famous East Qinling-Dabie Mountain molybdenum metallogenic belt in China.Based on the comprehensive study of lithology parameters and diagenetic and metallogenic geological conditions in this area,this paperindicates that the formation of molybdenum ore in this area is directly related to the genesis of the Tianmushan super-unit granite intrusive in the late Yanshan,and analyzes the characteristics of the pluton,the distribution characteristics of anomaly elements and the source of ore-forming materials in this area,which in order to provide a basis for mine evaluation or prospectingthe similar deposits.
