综合物化探方法在地质找矿“攻深找盲”中的应用

The application of integrated geophysical and geochemical exploration methods to the prospecting for deep and concealed orebodies

物化探找矿方法面临着新形势下复杂地质条件中找矿的新挑战,单一物化探分析方法很难具有说服力,综合各种地质信息和勘探方法显得尤为重要。笔者结合河南省某矿床的找矿实践,介绍了高精度磁测、X荧光土壤分析和EH4测深等物化探综合分析方法,在工作区内发现了与成矿有关的物化探异常,经查证与地表地质现象吻合较好,说明该综合物化探评价技术方法在该矿床的应用是成功的,显示了其快速、高效和精准的特点。

The integrated geophysical and geochemical prospecting methods are faced with challenge from complex geological condition, A single geophysical or geochemical analysis method is not persuasive, and hence the integration of various geological information and exploration methods is particularly important. The application of the integrated geophysical prospecting method system to a deposit in Henan Province is described in this paper based on practice. According to geological data and concrete geological facts, geophysical methods such as high precision magnetic survey, X-ray soil analysis and EH4 were used in an integrated way for concealed ore body prospecting. A clear geophysical and geochemical anomaly is related to metallization and matches well with geological phenomena, which suggests that the integrated geophysical and geochemical prospecting method system is effective in the molybdenum deposit, and it has the advantages of rapidity, efficiency and practicality.
