The Application Of The Geophysical Methods To Exploration In Ma Ti Gou Area

This paper mainly studied the regional geological background,geological characteristics,geophysical and geochemical of Ma Ti Gou deposit,and it has been confirm the stratigraphy,tectonics,igneous rocks and mineralization characteristics through the field works.The application of galvanic method delineated 6 high-polarized anomalous anomalies in the gold mine miaomiao section of Maqugou,and 7 anomalous anomalies.Completed 9 sections of induced-electricity sounding in the Miaogou section and interpreted the main anomalous areas;In the west-western segment,a total of six anomalous anomalies were identified,providing suggestions for further geological work in the region;Five anomalous electrical anomalies were delineated in Area Qian ya shu,and a preliminary evaluation of the mineralization prospect of this area was conducted;Verification of anomalous geochemical anomalies in section Qian shu gou using a small amount of polarimetric mid-section work;Using Stabilized Ladder and Immersion Sounding to Measure Geological Anomalies.Based on the comprehensive analysis of the mining area data and the comparison with the adjacent ore deposits,the ore-forming laws and ore-prospecting signs are summarized,and the metallogenic prediction work is carried out at the same time.The research results are obtained as following:(1)The main prospecting target layer in the Maqugou gold deposit is located in the back north wing of A Jingwei Bay.Strictly controlled by the characteristics of the reverse thrust distribution,a group of northwest and west formed by Miaogou main fault zone.A series of northeast-southwest extensional faults superimposed and modified in later stages.(2)Wall rock alteration,silicification,limonite mineralization,fading and alteration,internal and external rock contact zone structure,and dyke are important signs for prospecting in this area.(3)The original gold ore body has obvious mid-high resistance and high polarization characteristics.Although there is less difference in electrical resistivity with surrounding rock,its high polarizability characteristics are sufficient to separate it from the background,especially when the gold ore body is in the structural fracture zone,it tends to show low resistance-High polarization characteristics and electrical differences between surrounding rocks are even more pronounced.
