【摘要】：近期相当长的时间内,各地固体矿产勘查项目中,有一定找矿突破者较少。其主要原因在于各种资料未进行深入的地物化特征的相互关系研究,资料数据特征相互关系研究较为不足。作者认为,在矿产勘查工作中,尤其针对隐伏矿体,各种勘查方法优化合理利用,对各种致矿信息特征的相互关系进行叠合、印证的综合研究显得尤为重要。本文基于《内蒙古自治区化德县田宝沟钨铜多金属矿勘查》项目的整体勘查过程,对不同勘查方法进行了合理优化利用并投入实施,取得了可喜的地质找矿成果。在综合研究了勘查区的成矿特征的基础上,进行了合理的找矿预测分析,对下一步勘查工作提供了重要指导意义。通过田宝沟钨铜矿区野外和室内各项研究工作,在圈定的7处1:10000综合土壤化探异常中,AP-5号化探综合异常内,发现两条与条带状相对高极化低阻异常相对应的黑钨矿化石英脉带。同时深部钻探工程也有揭露。分析得出,AP-5号化探综合异常深部具有钨矿体品位变富、厚度变厚的趋势;AP-2、AP-6等两处具有重要成矿潜力;认真、扎实做好前期地质、化探、物探等扫面工作,是提供找矿线索最为重要的基础工作;着重研究具有条带状、串珠状或椭圆状等形态具一定规律性的综合异常(包括地质矿化异常)特征,是供化探、电法、磁法以及槽探、钻探等勘查方法适时优化应用的重要依据;化探异常、极化率异常走向及其几何形态结合矿化脉进行分析,是缩小找矿范围的重要思路和方法;矿体受岩体热液上涌产生的内部构造裂隙系统控制,构造裂隙为矿体的赋存提供了良好的储矿空间;研究区黑钨矿成矿模式为岩浆热液上涌产生放射状构造裂隙系统模式,为充填交代(石英脉)型钨矿床,呈钨矿“五层楼”模式。
[Abstract]:For a long time in the near future, there are few solid mineral exploration projects.The main reason lies in the lack of in-depth research on the relationship between geophysical and chemical characteristics of various data, and the lack of research on the interrelation of data features.The author believes that in mineral exploration, especially for concealed orebodies, the optimization and rational utilization of various exploration methods and the superposition of the interrelation of various ore-causing information characteristics are particularly important.Based on the whole exploration process of Tianbaogou tungsten and copper polymetallic ore exploration project in Huade County, Inner Mongolia Autonomous region, this paper optimizes the utilization of different exploration methods and puts them into practice, and obtains gratifying geological prospecting results.Based on the comprehensive study of the metallogenic characteristics of the exploration area, a reasonable ore prospecting prediction analysis is carried out, which provides important guidance for the next exploration work.Through field and laboratory research in Tianbaogou tungsten-copper mine area, two wolframite fossil veins corresponding to banded relatively high polarization and low resistivity anomalies were found in 7 delineated integrated geochemical anomalies of 1: 10000 integrated soil.At the same time, deep drilling projects have also been exposed.It is concluded that in the depth of the comprehensive anomaly of QianAP-5 geochemical exploration, the tungsten ore body has become rich in grade and the thickness is thicker and the two places, such as AP-2 and AP-6, have important metallogenic potential, and have done well the work of sweeping surface of Prophase geology, geochemical exploration and geophysical prospecting, etc, in earnest and in a down-to-earth manner.It is the most important basic work to provide the clues for prospecting, especially to study the comprehensive anomaly (including geological mineralization anomaly) with certain regularity in the shape of strip, bead or ellipsoid, which is used for geochemical exploration, electrical method, magnetic method and trough exploration.The important basis for optimizing the application of exploration methods such as drilling, geochemical exploration anomalies, polarization anomalies and their geometric patterns combined with mineralized veins are important ideas and methods to narrow down the scope of prospecting.The orebody is controlled by the internal structural fissure system of hydrothermal upwelling of rock mass, which provides a good storage space for the occurrence of orebody, and the wolframite metallogenic model in the study area is the radial structural fissure system model of magmatic hydrothermal upwelling.In order to fill the metasomatic (quartz vein) type tungsten deposit, the five-story model of tungsten deposit is presented.
