青海省玛多县抗得弄舍矿区地球物理特征及其地质意义

Geophysical Characteristics and Geological Significance of the Periphery of the Kangdenongshe Deposit in Qinghai Maduo

本次工作通过物探方法与地质找矿方法相结合,对详查区金矿体东、西部延伸方向有利成矿区块进行了1/1万激电中梯测量工作,进一步追索了已知矿体在东西方向上(普查区)的延伸情况,全面总结了抗得弄舍金多金属矿床的地质-地球物理特征、主要控矿要素,重点开展了普查区物探异常与详查区异常的研究与对比,通过对视充电率衰减率的分析,甄别异常源类型,建立初级地质-地球物理模型,配合适量的钻探工程对矿化蚀变地质体、异常源等进行深部验证,提出了下一步勘查工作方向。

Through the combination of geophysical methods and geological prospecting methods, carried out 1/10000 IP central gradient array method on the favorable metallogenic blocks in the eastern and western extension of the gold ore body in the preliminary exploration area, and further identified the extension of the known ore body in the east-west direction （reconnaissance area） o We summarize the geophysical-geological characteristics, main ore-controlling factors of the Kangde-nongshe Gold-polymetallic deposit, andfocuse on the research and comparison of the geophysical anomalies in the reconnaissance area and the anomalies in the preliminary exploration area. By analyzing the apparent charging rate, screening the abnormal source type, establishing the primary geology - geophysical model, carrying out appropriate amount of drilling engineering to deeply verify the mineralized alteration geological body ,abnormal source ,put forward the next direction of exploration work.
