马思罗金矿区地处扬子地台与松潘-甘孜地槽的接壤地带,处于康滇地轴的西缘,冕西金矿集中区的南延部分。近年来,部分学者从该地区岩石的宏观产出特征、岩相学特征、围岩蚀变特征等认为区内地层中原定的碳酸盐岩沉积岩(1∶20万区调报告)应属岩浆碳酸岩(张志斌等,2013;张丽敏等,2014),认为由幔源成因的岩浆碳酸岩和其引发的碳酸岩化作用造成了本区金元素的初步富集,为本区金矿的找矿提供了新的思路。本文对该矿区的岩矿石开展了系统的微量元素地球化学特征研究,以期
Mastello gold mining area is located in the junction of the Yangtze platform and Songpan - Ganzi trough in the western margin of the axis of the Kangdi Dian, Mianxi gold concentrate area south extension. In recent years, some scholars believe that the carbonate sedimentary rocks (1: 200,000 regional tone reports) in the strata of the area should be classified as macroscopic output characteristics, lithofacies characteristics and wall rock alteration characteristics of the area Magmatic carbonatites (Zhang Zhibin et al., 2013; Zhang Limin et al., 2014) argue that the magmatic carbonatites that originated from the mantle source and their carbonatation led to the initial enrichment of gold elements in this area Mine provides a new way of thinking. In this paper, the systematic study of trace element geochemistry of rock ores in this mining area
