内蒙古海苏沟多金属矿田成矿模式与找矿前景

Metallogenic model and prospecting prospect of Balinzuoqi haisugou in Chifeng,Inner Mongolia

海苏沟多金属矿田是黄岗—甘珠尔庙锡多金属成矿带的重要组成部分。海苏沟多金属矿田位于浩尔吐—小井子复背斜的核部,岩浆活动强烈,包括铜钼矿床2处、铅锌银矿床3处,但相关地质研究程度较低。该区矿化类型包括热液石英脉型铜钼矿化、浸染状钼矿化、矽卡岩型铅锌矿化、热液脉型铅锌银矿化、云英岩型锡矿化、矽卡岩型锡矿化等;蚀变以矽卡岩化、褐铁矿化、硅化为主,次为云英岩化、磁铁矿化、黄铁矿化、孔雀石化等。文章在野外一线观察的基础上,总结了矿田控矿特征,分析了成矿期次,建立了矿田岩浆热液成矿模式,并指明了矿田找矿方向和找矿前景。

Haisugou polymetallic ore field is one of the important components of Huanggang-ganzhuermiao polymetallic metallogenic belt. The Haisugou polymetallic ore field is located in the nuclear part of the Holtui-Xiaojingzi compound anticline, and there is strong magmatic activity, including copper Molybdenum deposits. There are 2 deposits, but the relevant Geological research is low. The types of mineralization in the area include hydrothermal quartz vein copper Molybdenum mineralization, leached Molybdenum mineralization, skarn lead and zinc mineralization, hot liquid vein lead and zinc silver mineralization, Yunyingyan tin mineralization, and skarn-type tin mineralization. The alteration is dominated by calcification, lignite mineralization, and silicification, followed by Yunying lithation, magnet mineralization, yellow iron mineralization, and peacock petrochemicals. On the basis of field observation, this paper summarizes the characteristics of mine control, analyzes the metallogenic period, establishes magmatic hydrothermal metallogenic model, and points out the prospecting direction and prospecting prospect.
