金及多金属矿化区找矿靶区分类分级——以鸡东金场沟矿区为例

Classification and grading of prospecting targets in gold and polymetallic mineralization area,taking Jinchanggou deposit in Jidong city as an example

利用地质类比法和综合信息法,以成(控)矿规律为基础,并结合总结提取的综合找矿标志(地质、地球物理与地球化学方面的综合信息),以标志信息量及信息量对比进行了靶区预测与分类分级。文中对金场沟矿区预测靶区进行了分类分级,为该区进一步的资源勘查提供了有价值、更为详实的线索,为提高后续找矿预测工作的有效性和准确性奠定了基础。

Based tion of the integrated on the metallogenic （ore-controlling） regularity, and combining with the summary and extraccriteria for ore prospecting （the comprehensive information about geology, geophysics and geochemistry.）, the prediction targets are classified and graded according to information quantum and their comparison. In the process, geological analogy and comprehensive information methods are used. The work provided a valuable and detailed reference for further resources exploration, and laid the foundation for the following prospecting and prediction in Jinchanggou deposit.
