    摘要:

    根据全国潜力评价的成矿规律研究成果,开展综合分析,将冈底斯成矿带东段划分了驱龙-甲玛铜多金属矿集区等13个矿集区,确定了主要矿集区中重要矿床的矿床类型,总结了矿床成岩成矿的时空分布和矿床组合等方面成矿规律,完善了矿床成矿系列、亚系列和矿床谱系,建立了中新世斑岩-矽卡岩型铜多金属矿的控岩控矿模式。提出燕山晚期-喜山早期冈底斯中部中酸性岩浆岩接触带似IOCG型铁铜金矿,早中侏罗世、中新世斑岩型铜矿外围的浅成低温热液金矿,与剪切带有关的构造蚀变岩型金矿等是冈底斯成矿带东段下一步找矿的重要矿床类型。

    Abstract:

    According to research achievements of metallogenic regularities of the national mineralization potential evaluation, we carry out a comprehensive analysis and divide the eastern section of Gangdese metallogenic belt into thirteen ore districts such as Qulong - Jiama copper polymetallic ore district. We also identified the main ore deposits types in major ore districts and generalized the spatial and temporal distribution features of the diagenetic or mineralization and detected the deposit type regularity. Based on the studies above the system of minerogenetic series, sub-series and deposit genealogy were improved and ore-controlling or petrology structure model of Miocene porphyry-skarn copper polymetallic deposits were established. Finally, we propose that these three ore deposits types are of great importance to prospect next step in the eastern section of the Gandese metallogenic belt i.e. in the central Gangdese the acidic magmatic contact zone analogue to IOCG iron-copper-gold deposits during late Yanshan-early Himalayan period, the epithermal gold deposits located in peripheral zone of porphyry copper deposit in early-mid Jurassic to Miocene, and the tectonic-altered gold deposits related to shear zone.
