| 摘 要： | 黑龙江多宝山矿田争光金矿位于中亚-蒙古斑岩铜矿带东部,近年来在该矿田内发现了多处铜钼、金矿床,显示区内良好的找矿前景。本文对该金矿床钻孔岩石剖面及地表岩石剖面测量的地球化学数据进行系统研究,分析了元素富集贫化的特征及规律,并总结出争光金矿的异常结构模式。研究发现,试验区内Na_2O、Ba、Sr形成的负异常突出而明显,是本区的找矿标志;在这些负异常的基础上,再着重考虑矿化剂元素S、主成矿元素Au及其伴生元素Ag、Cd等元素的异常。利用这样的异常结构模式,提出了争光矿区下一步找矿方向,并为相同类型矿床的勘探提供参考。

| Abstract: | The Zhengguang gold deposit of the Duobaoshan ore field in Heilongjiang Province is situated in the east of the Central Asia-Mongolia porphyry copper belt.In recent years a number of copper molybdenum deposits and gold deposits have been found in this field,indicating a good prospect of ore search.This work made a systematic study of the data of drill cores and geochemical measurement on the surface,analyzed the characteristics of element enrichment and depletion,and established a model of the geochemical anomaly structure of the Zhengguang gold deposit.Research shows that the negative anomalies of Na2 O,Ba and Sr are very prominent in the deposit,which should be the primary mark of ore metallogenic prediction in this area.And then,the mineralization element S,major ore-forming element Au,associated elemnents,such as Ag and Cd,should be taken into consideration.Such a model of the anomaly pattern permits to suggest the direction of prospecting in the Zhengguang mine and serve as the reference for metallogenic prediction in similar deposits. |
