多宝山矿床受北西向压扭性帚状构造带控制,矿化富集地段是几组构造裂隙交汇部位.矿带与矿体主要赋存于片理化和压碎蚀变的花岗闪长岩内,小部分产于蚀变安山玢岩和花岗闪长斑岩内.根据矿物组合特点,矿区蚀变花岗闪长岩、花岗闪长斑岩可分为四个蚀变带,即硅化-钾钠硅化核-石英核、钾长石-黑云母化带、石英-绢云母化带、青盘岩化带.硅是蚀变带中活动强烈的元素,但只在伴有含钾矿物时才与成矿关系密切.
The Duobaoshan deposit is under the control of a northwestward compressive broom-like tectonic belt, where the mineralized enrichment zone is where several groups of structural fissures meet. The orebodies and orebodies occur mainly in the granodiorite and crushed altered granodiorite , A small part of the alteration andesite and granodiorite porphyry.According to the characteristics of mineral assemblage, the alteration granodiorite and granodiorite porphyry in the mining area can be divided into four alteration zones, namely silicification - Potassium silicate nuclei - Quartz, K-feldspar - biotitization, Quartz - sericitization, and lithosphere lithification. Silicon is an active element in the alteration zone, but only in the presence of potassium-bearing minerals When it is closely related with the mineralization.
