摘要
宁夏卫宁北山二人山地区位于阿拉善微陆块南缘,是宁夏境内重要的热液成因多金属矿产成矿区之一。为服务该地区下一步在外围及深部的找矿,在钻孔岩石地球化学测量的基础上,对该地区多维异常体系进行探讨。结果表明:在该地区已知多金属矿(化)体中,发育着以常量元素Na2O为主要特征的负异常体系、以S为代表的矿化剂元素异常体系、成矿及其伴生元素异常体系等,证实了多维异常体系的存在,并进一步在多维异常体系理论的指导下圈定了研究区成矿条件和成矿潜力有利区域。研究成果是卫宁北山地区热液型多金属矿找矿优选地球化学勘查方法的新尝试,对该区地质找矿具有重要的实用价值。
Errenshan area of Weiningbeishan is located in the southern margin of Alashan microcontinent,which is one of the important hydrothermal polymetallic mineralization areas in Ningxia.In order to serve the next prospecting in the periphery and deep part of the area,the multidimensional anomaly system in this area was discussed on the basis of borehole rock geochemical survey.The results show that in the known polymetallic ore bodies in this area,there are negative anomaly systems characterized by major element Na2 O,mineralization agent element anomaly system represented by S,mineralization and associated element anomaly system,etc.,which confirms the existence of multidimensional anomaly system.Under the guidance of the theory of multi-dimensional anomaly system,the metallogenic conditions and favorable areas of metallogenic potential in the study area are further delineated.The research result is a new attempt to optimize geochemical exploration methods for hydrothermal polymetallic deposits in Weiningbeishan area,and has important practical value for geological prospecting in this area.
