属于地表没有露头的矿床,有矿体与围岩均被年轻的沉积所复盖的被复矿床,和矿体在现代侵蚀剖面上还未露出地表的隐藏矿床.本文主要是以东北某铅锌矿床为例,讨论如何根据赋存盲矿体的地质构造特点及地面标志来决定这类矿床的勘探方法问题.一、隐藏矿体的地面标志对盲矿体的地面标志,我们不准备从理论上去分析.为了讨论方便,仅对该矿床的地质情况作如下扼要说明:东北某铅锌矿床赋存于云母片岩复盖下的瓦层带(云母片岩与白云石大理岩瓦层,以后简称瓦层带)及基部白云石大理岩的上部.矿脉生成与断裂密
Belonging to the ore bed without outcrop on the surface, the re-deposit bed covered by young sediments of ore body and surrounding rock, and the hidden deposit of the ore body that has not been exposed on the surface of the modern erosion profile.This paper mainly uses a lead-zinc Deposit as an example to discuss how to decide the method of prospecting for such deposits according to the characteristics of geological structure and surface markers of the depositing blind orebodies I. Ground markings of hidden ore bodies We do not intend to interpret the ground markings of blind ore bodies from the theory For the sake of discussion, only the geological conditions of the deposit are briefly described as follows: A lead-zinc deposit hosted by mica schist in the northeastern region is a layer of lamella (mica schist and dolomite marble, hereinafter referred to as tile Belt) and the upper dolomite marble basement
