金铜成矿带成矿地质特征与找矿潜力分析——以王厝金矿为例

为总结闽北大药坑—王母山—东游金铜成矿地质特征及找矿潜力,以福建省建瓯市王厝金矿区为例,从矿区地层特征、矿床地质特征角度进行了综合分析,对成矿带的金铜银矿产成矿规律进行了总结,并进行了矿产综合评价与潜力分析,认为该区域具备较为良好的找矿潜力,可以为成矿带找矿方向及后期找矿预测工作提供基础地质依据和支撑。

新疆青河克孜勒他乌金成矿带地质特征和找矿方向

克孜勒他乌金铜成矿带位于加波萨尔古生代岛弧区,卡拉先格尔成矿带,该成矿带受卡依尔特一二台断裂控制。克孜勒他乌花岗闪长岩体侵位于上泥盆统中-基性火山岩夹碎屑岩中。工作区内黄铁矿化、褐铁矿化、碳酸盐化、硅化、孔雀石化等蚀变发育。本文结合物化探特征,认为克孜勒塔乌金矿具有良好的寻找斑岩型铜钼(金)矿的前景。石英脉型金矿点也有望发现有工业意义的小型金矿床。

新疆特克斯县阔拉萨依多金属矿区地质特征及成矿条件分析

阔拉萨依多金属矿区属伊犁金铜成矿带—伊什基里克成矿亚带。按苏联学者A·Л什穗列维奇的划分 ,伊什基里克成矿亚带西延可能与卡捷斯克—钠尔金带相接。该成矿带以中低温热液成因的Au、Cu、Zn、Ag等矿化多见 ,兼有Bi、Mo等高温热液矿化。这些矿化大部分都发育在岩浆带—尤其是浅成岩带 (包括火山机构 )附近。

Geological characteristics and metallogenic prognosis of main gold deposit in Altai gold ore belt, Xinjiang

Altai polymetallic mineralization belt is famous copper-polymetallic mineralization belt in the world. There are a lot of gold deposits in the Altai ore belt in Xinjiang, China. These gold deposits belong to two genetic types: volcanogene late-stage hydrothermal type and fractured altered rock type. The authors discuss mainly the geological and mineralized features of fractured altered rock type of gold deposits in Altai gold ore belt. Base on this study, the metallogenic law is summarized and the deep metallogenic prognosis has been done in Duolanasayi and Tuokuzibayi gold deposits, and some mineralized anomalys have been discovered.
