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。
Taking the 1: 200,000 natural heavy sand measurement data in Shanxi Province as an example, taking the copper mineral heavy sand as an example, we briefly introduce the delineation of abnormal heavy sand assemblage. In Zhongzhushan metallogenic belt, a total of 5 natural copper sand mineral natural sand abnormalities , Of which 2 were abnormal in level Ⅰ, 2 were abnormal in level Ⅱ and 1 was abnormal in level Ⅲ. The Grade I anomaly of Chencun Town in Zhongtiaoshan is located in the highly anomalous zone of Laojundian which includes Henglingguan deposit, Tongkuangyu deposit and Xumao Gongdian deposit, and the Hu-gob type deposit, Henglinguan deposit and copper deposit The Yuguang deposit co-locates in the region of low negative and negative magnetic anomalies and anomalously coincides with the geochemical exploration after fractal theory processing. According to the analysis of the geological features in the anomaly area, it is considered that the anomaly range delineated by the heavy mineral sand of copper ore has good prospecting significance and can provide direction for the next step of work.
