摘要

为了评价内蒙古靠山屯勘查区银铅多金属矿床找矿前景,对该勘查区进行了地质、航磁激电和化探综合找矿信息的提取。结果表明,靠山屯银铅多金属矿床是以银为主,伴生有铅和锌的中型矿床,产于早白垩世钾长花岗岩和晚侏罗世凝灰岩内。蚀变和矿化特征显示该矿床成因类型为中温热液脉型。上侏罗统玛尼吐组火山岩富含Pb、Ag等成矿元素,是有利的容矿围岩,产于火山岩和岩体接触带附近的断裂构造是有利的控矿构造,绢英岩化和硅化是近矿的围岩蚀变。成矿后区内存在差异性抬升,中部和北东部矿化以方铅矿和共伴生银矿物为主,矿床保存条件好,如Ⅱ和Ⅲ号蚀变带。南西部以闪锌矿(含黄铜矿)为主,矿床剥蚀较大,如Ⅰ号蚀变带,中高极化、低阻或中高阻、低-中高磁异常的物探异常总体为矿致异常的特征。Pb、Zn、Ag异常套合好,Pb和Ag异常面积大,强度高的异常 KHt4-11分布区矿床保存条件较好,找矿前景较好。Zn异常面积大,外侧的Pb和Ag异常面积小的异常KHt1 KHt3分布区矿床剥蚀较大,找矿前景较差。

Abstract:

In order to determine the prospecting potential of Kaoshantun silver-lead polymetallic deposit in Inner Mongolia, the authors extracted the geology, aeromagnetic excitation and geochemical prospecting information. The results show that the Kaoshantun silver-lead polymetallic deposit is a medium scale of deposit which mainly contain silver accompanied by lead and zinc, which occurs in both of moyite in Early Cretaceous and tuff in Late Jurassic. The alteration and mineralization characteristics show that the genetic type of the deposit is medium hydrothermal vein type. The volcanic rocks in Upper Jurassic Manitu Formation are rich in Pb and Ag, and are favourable ore hosting rocks. The faults near the volcanic rocks and rock contact belts are favorable ore controlling structures, and the phyllic alteration and silicification are closely related to the alteration of surrounding rocks. The diverse uplift occured after mineralization, the mineralization in the middle and northeast of the exploration area is mainly galena and associated silver minerals, and the deposit was well-preserved as alteration belt Ⅱand alteration belt Ⅲ. The southwest of exploration area is mainly sphalerite (chalcopyrite), with high degree of denudation, for example alteration beltⅠ, which is characterized by medium-high polarization, low or high resistance, low-high magnetic anomaly. The anomalies are good identity of concentration for Pb, Zn, and Ag elements, with large abnormal area of Pb and Ag. The KHt4-11 distribution with high abnormal intensity has a good preservation condition and prospect. The Zn anomaly area is large, and the abnormal distribution of Pb and Ag anomaly in the outside of the KHt1 and KHt3 distribution area is large with poor prospecting potential.
