为调查安徽省重要矿集区地球物理参数,对岩石电性参数存在各向异常进行研究。选取安徽省霍邱矿集区、庐枞矿集区、宁芜矿集区、东至—泾县成矿带等4个地区的沉积岩、变质岩为样本,分别进行3个方向的电阻率、极化率测试,测试结果证实:沉积岩、变质岩、火山沉积岩都存在非常明显电阻率各向异性,电阻率越高,其垂向电阻率与水平方向电阻率比值越大;岩石极化率各向异性不明显。通过岩石电性参数各向异性数据分析,总结了岩石电性参数各向异性特征,为电法勘探综合解释提供基础资料及依据。
In order to investigate the geophysical parameters of important ore deposits in Anhui Province, the anisotropy of the electrical parameters of rocks was studied. The sedimentary rocks and metamorphic rocks in four areas of Huoqiu ore district, Luzong ore district, Ningwu ore district and east to-Jingxian metallogenic belt were chosen as samples, resistivity, The test results show that the sedimentary rocks, metamorphic rocks and volcanic sedimentary rocks have obvious resistivity anisotropy. The higher the resistivity is, the higher the ratio of the vertical resistivity and the horizontal resistivity is. The rock polarizability Not obvious to the opposite sex. Through the anisotropic data analysis of rock electrical parameters, the anisotropy characteristics of rock electrical parameters are summarized, which provide the basic information and basis for the comprehensive interpretation of electrical prospecting.
