大面积出露于川滇黔地区的峨眉山大火成岩省内,分布有许多铜矿点和铜矿化点,前人根据产出的空间位置,将其分为三类(张正伟等,2004)(沉积型、热液型、风化淋滤型)。其中在玄武岩里发现的热液型铜矿是近年来矿床学界研究较多的一类型,而有关风化淋滤型铜矿的研究报道却相对比较少 Large areas are exposed in the Emeishan large igneous province in Sichuan, Yunnan and Guizhou provinces. There are many copper deposits and copper mineralization sites. According to their spatial location, the predecessors classify them into three types (Zhang et al., 2004) ( Sedimentary, hydrothermal, weathering leaching). Among them, hydrothermal copper deposits found in basalts have been the most studied in mineral deposits in recent years. However, there are relatively few reports on the weathering and leaching copper deposits
