自然重砂异常圈定及其对中条山铜矿的找矿指示意义

INDICATION OF HEAVY MINERAL ANOMALY TO THE EXPLORATION OF ZHONGTIAOSHAN COPPER DEPOSIT

利用山西省1∶20万自然重砂测量数据,以铜矿物重砂为例,简要介绍了重砂组合异常的圈定,在中条山成矿带共圈定铜族矿物自然重砂异常5个,其中Ⅰ级异常2个,Ⅱ级异常2个,Ⅲ级异常1个。中条山陈村镇Ⅰ级异常位于老君殿高重异常区(该异常内包含横岭关矿床、铜矿峪矿床和徐茂公殿矿床),与胡—篦型矿床、横岭关矿床和铜矿峪矿床共同处在区域低缓负磁异常中,且与分形理论处理后的化探异常吻合。根据异常区内地质特征分析,认为本次铜矿物重砂所圈定的异常范围具有较好的找矿指示意义,可以为下一步工作提供方向。

This paper, based on Shanxi＇ s l：200k heavy minerals survey,uses copper heavy minerals to introduce the lineation of heavy minerals combination anomaly. Zhongtiaoshan copper zone is composed of five copper anomalies, 2 Class Ⅰ, 2 Class Ⅱ and Ⅰ Class Ⅲ. Chencun town Class I anomaly is located in Laojundian high anomaly zone, where possesses Henglingguan, Tongkuangyu and Xumaogongdian copper deposits, also in a low and gentle minus magnetic anomaly with Hu-Bi type, Henglingguan and Tongkuangyu deposits, consistent with chemical anomaly after Fractal processing. This anomaly shows a good indication for copper potential combined with the geology and offers the guideline for next work.
