音频大地电磁法、地面高精度磁法在黑龙江三江盆地西部铀矿资源勘查中的应用
Application of Audio-Frequency Magnetotelluric Method and Ground High Precision Magnetic Method in Uranium Exploration in the Western Sanjiang Basin,Heilongjiang Province
摘要
Abstract
Audio magnetotelluric(AMT)and ground high-precision magnetic methods are becoming increasingly important means of detecting the ore-forming environment of uranium deposits.There are certain physical differences in the electrical and magnetic properties of the target strata and surrounding rocks in the western Sanjiang basin,Heilongjiang province.Based on this,AMT and high-precision magnetic measurement was carried out to explore the deep uranium ore-forming environment.The results show that the main underground electrical information in the study area was preliminarily identified using AMT,and different strata in the study area were interpreted by combining physical property data and resistivity logging information.As an auxiliary method of AMT,ground high-precision magnetic method helped to interpret multiple structures,and these interpretation results were in good consistence with known drilling information.Through comprehensive analysis above,the stratigraphic structure of the study area was determined,and key ore-forming elements such as fault structures were effectively identified,providing important basis for further uranium resource evaluation in the study area.关键词
