本文从元素地球化学异常场(简称异常场)受板块移动所制约的观点出发,依据西南冶金地质勘探公司编制的地球化学异常(重砂、次生晕)图,讨论云南境内锡(锡、钨)、汞-锑、镍-铬(金)元素地球化学异常场的分布特征及某些矿产的找矿方向. 云南大地构造概况云南地处印澳板块、欧亚板块及太平洋板块的汇聚区附近(图1),西界位于印澳板块的印度板块和欧亚板块的中国板块缝合 Based on the geochemical anomalies (heavy sand and secondary halo) maps prepared by Southwest Metallurgical Geological Prospecting Company from the point of view of the element geochemical anomaly field (abbreviated as anomalous field) restricted by plate movement, ), Mercury-antimony, nickel-chromium (elemental) geochemical anomalies and the prospecting direction of some minerals Yunnan Geotectonic Profile Yunnan is located near the converging area of ​​the Indian and Australian Plate, the Eurasian Plate and the Pacific Plate (Figure 1). The western boundary is located in the Indian Plate of India-Australia Plate and the Chinese Plate of the Eurasian Plate.
