我国西南地区及越南北部含有大量与峨眉山玄武岩有关的基性-超基性岩体,这些岩体成带状分布(图1),不同岩带中的岩体矿化差异明显,跨四川、云南两省的盐源—丽江—弥渡岩带中金宝山岩体为贫Cu、Ni富Pt、Pd矿化;四川北部的道孚—丹巴—康定岩带中杨柳坪岩体为富Cu、Ni、Pt、Pd矿 The southwestern China and northern Vietnam contain a large number of mafic-ultrabasic rocks associated with the Emeishan basalts, which are distributed in zonal distribution (Fig. 1). The mineralization of rock mass in different rock belts is obviously different. It extends across Sichuan and Yunnan The Jinbao Baoshan rock mass in the Yanyuan-Lijiang-Midu rock belt of the two provinces is mineralized by Cu and Ni-rich Pt and Pd; the Yangupingping rock mass in the Daofu-Danba-Kangding rock belt in northern Sichuan is rich in Cu, Ni, Pt, Pd ore
