地球化学方法广泛而有效地应用在寻找和评价金属矿床。目前由于容易开采的矿床(地表出露的矿床)频于衰竭,因而特别提高了用地球化学方法深部找矿的意义,首先是根据原生地球化学晕寻找金属矿床。最近几年来,在研究和实际采用原生晕及与其伴生的次生指示元素的岩石化学晕方面也获得了很大成绩。根据岩石化学晕寻找盲矿体的深度相当大,在很多情况下可达一公里。目前这种方法在寻 Geochemical methods are widely and effectively applied in the search and evaluation of metal deposits. At present, due to the frequent depletion of easily mined deposits (surface exposed deposits), the significance of using geochemical methods for deep prospecting is especially enhanced. The first step is to search for metallogenic deposits based on the primary geochemical halo. In recent years, great achievements have also been made in the study and practical application of primary halo and its associated secondary indicator elements. The search for blind orebodies based on petrochemical drowsiness is quite large in depth, up to one kilometer in many cases. This method is currently looking for
