摘要
本文对甲乌拉大型银多金属矿床主要控矿断裂破碎带、蚀变带、矿化带及围岩中的元素富集规律进行了初步探讨,分析了断裂构造与成岩成矿的时空关系,探讨了成矿断裂的构造地球化学特征及断裂构造地球化学障的控矿机制,提出了找矿预测标志。
Element enrichment regularity in major ore-controlling fractured,alteration and mineralizationzones as well as in coutry rocks of the large sized Jiawula Ag-bearing multimetallic deposit is discu-ssed.After an analysis on the time space relationship between fractured structure and diagenesis me-tallogenesis,teotonochemical features of the ore forming fractures,and the ore-controlling mechanismof the tectonogeochemical barrier,several guides for ore exploration and prognosis are suggested.
