麦康奈尔镍矿床是一个椭圆形角闪岩-黑云母石英闪长岩pod，位于围绕着萨德伯里火成岩杂岩主体的萨德伯里变质角砾岩中。矿床的几何形状为板状，走向长约152米，深度约610米。在该研究区进行了各种磁测量。安大略省地质调查局进行了一项区域航磁调查。在解释成因体的特征时，使用了更详细的地面磁测量和钻孔磁测量。在40 m、105 m、135 m、210 m和250 m处与矿床相交的5个钻孔，对矿床的岩性控制具有较好的深度控制作用。本研究中使用的其他8个井眼没有测井岩性，但所有13个井眼都使用伽马射线、密度、谱伽马伽马、激电、电阻率、SP、磁化率、温度和3分量磁场探头进行了测井。只有磁化率和3组分的测量…
The McConnell nickel deposit is an elliptical amphibolite‐biotite quartz diorite pod within the Sudbury Metabreccia that surrounds the main mass of the Sudbury Igneous Complex. The geometry of the deposit is tabular with a strike length of approximately 152 m and depth extent of 610 m. Various magnetic surveys were conducted in this study area. A regional aeromagnetic survey was conducted by the Ontario Geological Survey. A more detailed ground magnetics survey and a borehole magnetic survey are used in the interpretation of the character of the causative body. Five boreholes which intersect the deposit at 40 m, 105 m, 135 m, 210 m, and 250 m provide good lithological control of the deposit with depth. Eight other boreholes used in this study did not have logged lithology, but all 13 holes were logged with gamma ray, density, spectral gamma‐gamma, IP, resistivity, SP, magnetic susceptibility, temperature, and 3‐component magnetic field probes. Only the measurements of magnetic susceptibility and 3‐compone...
