贵州织金——五指山地区1∶5万地磁资料揭示的蚀变信息及找矿地质意义
|
摘要
据贵州省矿产资源潜力评价预测,黔西北铅锌找矿前景大,近年来相继发现了织金五指山、赫章猪拱塘两个大型、超大型铅锌矿床,取得历史性突破。为实现更上一层楼,贵州省地矿局实施了"黔西北地区铅锌找矿系列攻关重大科研专项"多个项目,本文是其中成果之一。项目通过对1∶5万地磁资料研究,挖掘相关地质找矿线索,在圈定的岩石蚀变带(或隐伏岩体异常带、矿致异常带)与化探异常重合区投入相应激电工作,在优选的激电异常区,再进行电磁法剖面测深测量,取得了较好的铅锌找矿效果。
According to the evaluation of mineral resources potential in Guizhou Province,the prospect of lead and zinc prospecting in northwest Guizhou is very promising.In recent years,two large-scale and super large-scale lead and zinc deposits have been found in Zhijin Wuzhi mountain and Hezhang pig-gongtang.In order to achieve a higher level,the Guizhou provincial bureau of geology and minerals has carried out several projects of"series of key scientific research projects on lead and zinc prospecting in northwest Guizhou".This paper is one of the achievements.The project has studied the 1∶50 000 geomagnetic data and excavated relevant geological prospecting clues in the delineated rock alteration zone(or the anomaly zone of concealed rock body and the anomaly zone caused by ore deposit).The belt and the mine-induced anomaly zone are combined with the geochemical anomaly overlap zone to input the corresponding IP work.In the preferred IP anomaly zone,the electromagnetic profile profilometry is performed,and a good lead-zinc prospecting effect is obtained,which is an important revelation.
