云南弥渡县金宝山铂钯矿床控矿因素分析

Analysis of Ore-Controlling Factors in Jinbaoshan Platinum Palladium Deposit in Midu County, Yunnan Province

云南弥渡县金宝山铂钯矿床位于我国著名的扬子准地台之楚雄凹陷内,区域大地构造位置独特,基性—超基性岩浆岩分布广泛,具有良好的找矿潜力。本文从矿区地层、构造和岩浆岩三个方面分析了矿区地质特征,从矿化特征与矿体产出部位、矿层划分及对比、矿体富集规律分析三个方面总结了矿体地质特征,进而总结了铂钯矿床的控矿因素和找矿标志,为区内进一步寻找铂钯矿提供指导。

Jinbaoshan Platinum Palladium Deposit in Midu County,Yunnan is located in the Chuxiong sag of the famous Yangzi quasi-platform in China,with unique regional tectonic position,wide distribution of basal-magmatic rocks,and good prospecting potential.This paper analyzes the geological characteristics of mining area from three aspects of formation,structure and magmatic rocks in mining area,summarizes the geological characteristics of ore body from three aspects,such as mineralization characteristics and ore body output location,Ore layer division and comparison,and analysis of ore body enrichment law,and then summarizes the ore-controlling factors and prospecting signs of platinum Palladium.
