黑龙江黑河争光金矿异常结构模式研究
A Model of Geochemical Anomaly Structure and Metallogenic Prediction in the Zhengguang Gold Deposit,Heilongjiang Province
摘要
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.关键词
