在黔西南贞丰背斜卡林型金矿研究区开展综合地球物理勘查项目的同时,为了数据反演和地质解释的需要,分别利用3522-50LCR电性测试仪、SM30手持磁化率仪、2G-760U-Channel岩石超导磁力仪和高精度物理天平对黔西南贞丰背斜卡林型金矿钻孔岩芯电阻率、磁化率、剩余磁化强度和密度进行了精细测量,得到了不同岩性岩石的各项物性参数,明确了卡林型金矿围岩的物性特征.在测量电阻率时特别注意测量样品2个方向的电阻率,发现了沉积岩在电性上的各向异性特征.数据显示该地区主要岩性岩石在不同物理性质上有不同差异.研究结果对于在该地区和地质条件相似的邻近地区开展卡林型金矿的地球物理勘探提供了方法选择的参考和测量数据反演必不可少的依据.

@@@@In order to meet the demands of data inversion and geological interpretation of the integrated geophysical exploration of Zhenfeng anticline Carlin-type gold deposit in southwest of Guizhou,we got collected all different kinds of physical property data of the drilling core and defined the physical characteristics of the wall rock by accurately measuring the resistivity,magnetisability,residual magnetization and density of the corresponding drilling core,using 3522-50LCR tester,SM30 magnetic susceptibility meter,2G-760U-Channel magnetometer system and high-precision physical balance.In particular,we measured the sample’s resistivity from both horizontal and vertical directions and get discovered the sedimentary rock anisotropy,which is reflected in resistivity.Data show that different rocks are different in physical properties more or less in the area.The result of the study is a useful reference for the choice of geophysical exploration methods and indispensably essential for the geophysical data reversion in this area and nearby.
