摘要
地质异常单元圈定矿产资源体潜在地段是以地质异常矿体定位理论为前提，应用综合信息定量标度“致矿地质异常单元”首先分析了铜石金矿田金矿成矿地质背景的综合信息特征，详细研究了“致矿地质异常”的组分分带趋势；推断了金矿产资源体系列形成的深部地质结构样式；在此基础上，选择控矿地质异常标志和地质矿异常标志作为构置成矿有利度的变量，利用成矿有利度圈定矿产资源体潜在地段.
The geological anomly unit methed (GALJM), based on the ore-forming theory for the location of the geological anomaly,is a new unit-classitication method for the application of the comprehensive information quantitative data to the measurement of the "ore-generating geological anomaly unit". In this paper, the analysis is made of the comprehensive information features of the gold-forming geological background of the Tongshi gold field; then a detailed investigation is presented into the component znation trend of the "ore-generating geological anomaly", and finally a pattern is the of the deep geological structure resulting in the gold mineral resources system.On there bases,the ore-controlling geological anomaly indicator and geological ore-deposit anomaluy indicator can both be used to consitute the variables favorable for the ore formation.In addition,the ore-forming favorability can be used to delineate the potential areas of the mineral resurces.
