摘要
对泰安地区东部金(铁)成矿远景区绿岩带金矿成矿条件进行了综合分析研究,对成矿远景区进行了划分.在对绿岩、花岗岩、韧性剪切带三要素在各区段的分布特征和绿岩带金矿成因分类分析的基础上,提出了绿岩带金矿是以韧性剪切带为主线,以绿岩为基础,以花岗岩为导火的三位一体成矿.以100分对三要素进行量化分解,并据此提出了成矿预测.指出成矿远景区内以往的找矿停留在同构造晚期初生型金矿床类型上.今后的找矿工作必须把握"三位一体"成矿模式,分析矿床成因类型,按照矿床成因类型的突出特点针对性地投入工作,必须加大投入,整装勘查.
With study on the metallogenic conditions for greenstone belt gold deposits in the Au （-Fe） prospect area in Eastern Tai＇an region, the ore prospect areas are divided. On the basis of analysis on genetic types of gold deposits and distribution of greenstone, granite and ductile shear zone, it is proposed that the metallogenesis of the greenstone belt gold deposits in the region is dominated by the ductile shear zone, based on greenstone, and triggered by granite. Ore prognosis is put forward with quantization for the metallogenic factors. It is suggested that further prospecting should follow the metallogenic model of greenstone-granite-ductile shear zone, with respect to the characteristics of genetic types of deposits.
