摘要
虎头崖矿田属于近年来新确立的青海省三轮成矿远景区划及找矿靶区预测中的青海省都兰三级成矿带(Ⅲ11)的西段部分,是青海省十分重要的铜多金属成矿区带。由于该铜铅锌多金属矿床的成矿作用复杂,对成矿控制因素的研究缺少系统性,导致对于矿区的成矿模型的建立仍然不是很明确,其已成为制约找矿突破的瓶颈。通过近年来的研究成果和笔者野外及室内综合分析,总结了与成矿关系密切的容矿地层、控矿构造、岩相分布和侵入体特征,初步建立了该矿田区主要成矿-控矿因素的空间关系,并提出了地质找矿标志。这些认识对进一步分析该区矿床特征、性质、成矿关系和构造背景,以及进一步找矿都将有重要理论和实践指导意义。
The Hutouya orefield is one of the important poly-metallic deposits in the Qimantage area of Qinghai province in recent years. However, as the mineralization of the copper lead--zinc poly-metallic deposit is very complex, and the study of ore-controlling factors is not systematic at present, the metallogenic model is not clear and the geochemical exploration work runs into bot- tleneck. Based on recent research results, the author＇s field and indoor synthetic analysis, this paper summarized ore formation, ore controlling tectonics, lithofacies distribution and intrusion characteristics. The article preliminarily established the spatial relationships of mineralization and ore-controlling factors in the Hutouya orefield, and put forward ore-prospecting indicators. All these conclusions will have important theoretical and practical significance for studying the depos it characteristics, properties, metallogenic relationship, tectonic background and further ore exploration.
