摘要
金宝山铂钯矿是我国近年来发现的贫铜镍大型铂钯矿床,文章通过对云南省弥渡县金宝山铂钯矿地质特征进行分析,认为矿区内铂钯矿体产于含云闪长铁质超基性岩中,呈似层状产出,主要赋存于橄榄岩。矿区内划为三个矿群,上矿群具有块状构造,岩石坚硬、致密,蚀变较强,矿石品位较高;中矿群位于中部,具聚斑状构造,岩石蚀变较弱,矿化度较低;下矿群产于超基性岩体的底部,具填隙状构造,岩石成分较复杂,蚀变较强,厚度稳定-较稳定、矿体形态简单,但是断层破坏较大,勘查类型为Ⅰ类型。
The Jinbaoshan Pt-Palladium deposit is a large copper-nickel-poor pt-Palladium deposit discovered in Recent years in China.Based on the analysis of geological characteristics of the Jinbaoshan Pt-Palladium deposit in Midu County,Yunnan Province,it is considered that the pt-Palladium ore body occurs in the ultrabasic rock containing dolomite diorite,which is stratified and mainly occurs in peridotite.The mining area is divided into three ore groups.The upper ore group has massive structure,hard and dense rock,strong alteration and high ore grade.The middling ore group is located in the middle part with porphyritic structure,weak rock alteration and low salinity.The lower ore group is located at the bottom of ultrabasic rock mass,with interstitile-like structure,complex rock composition,strong alteration,stable thickness,simple ore body shape,but large fault damage,and the exploration type isⅰtype.
