豫西外方山金矿集中区的物探数据处理结果及其地质解释说明:伏牛山杂岩基属中深岩浆成因,呈南陡北缓侵入于熊耳群地层中,在浅部呈两个较小的岩基,它们分别是太山庙和合峪岩体,这两个岩体与浅部的脉岩系同源产物;与脉岩相伴的金矿床分布在这两个较小岩基北侧的断裂中,在金矿集中区的下部,物探数据向下延拓处理结果表明有隐伏岩体,它们可能是金矿床形成的热动力和矿质的来源(至少是部分)。在重力异常图上,金矿床(点)分布于1)布格重力异常陡变带;2)布格重力异常陡变带的转弯处;3)线性异常带附近;4)布格重力异常低值区,靠近高值一侧等值线由疏变密部位。在磁异常图上则位于:磁异常梯度带、同形扭曲带、磁场截然分界线或线状及串珠状异常带上;磁能高值区。
The results of geophysical data processing and geological interpretation of the western part of the Western Fushan gold deposit in the west of Henan indicate that the Funiu Mountain complex is a medium-deep magmatic origin and intruded into the Xiong’er Group strata northward and southward, They are the Tai Shanmiao and Heyu plutons, respectively. These two rock masses are homologous products with the veins of the shallow part. The gold deposits associated with the veins are distributed on the north side of the two smaller ones In the lower part of the gold concentrate, the downward continuation of the geophysical data indicates that there are hidden rocks that may be at least partially a source of thermodynamics and minerals formed by the gold deposit. On the gravity anomaly map, the gold deposits (spots) are distributed in 1) Bouguer gravity anomaly abrupt zone; 2) Bouguer gravity anomaly transition zone; 3) near the linear anomalous zone; 4) , Close to the high side of the contour by the sparse dense part. In the magnetic anomaly map is located: magnetic anomaly gradient zone, isomorphic distorted zone, magnetic field cut-off line or linear and beaded anomaly zone; high magnetic energy zone.
