在河南省信阳地区新发现金伯利岩体，其位于华北地台南缘，岩石中普遍含金刚石指示矿物。本研究开展金刚石勘查地质研究，同时运用高精度磁法、激发极化法、大地电磁测深法等地球物理手段对金伯利岩体进行探查。基于区内金伯利岩的地质与地球物理特征，系统总结了各物探方法的异常特征，并通过钻探验证评估了物探方法的找矿效果。研究表明：高精度磁法可有效圈定金伯利岩体分布范围；激发极化法与大地电磁测深法可揭示岩体深部延伸及产状特征。综合物探方法在金伯利岩体探测中展现出显著效果，为间接寻找金刚石矿提供了重要技术支撑。
Abstract：A new Kimberlite body has been discovered in the Xinyang area of Henan province, which are located at the southern margin of the North China Craton and generally contain diamond indicator minerals in the rocks. This study conducted geological research on diamond exploration, while employing geophysical methods such as high-precision magnetometry, induced polarization(IP) method, and magnetotelluric(MT) method to investigate the Kimberlite body. Based on the geological and geophysical characteristics of the Kimberlite in the study area, the response characteristics of each geophysical method were systematically summarized, and the prospecting effectiveness of these methods was evaluated through drilling verification. The research indicates that highprecision magnetometry can effectively delineate the distribution range of the Kimberlite body, while the induced polarization method and magnetotelluric method can reveal the deep extension and structural attitude characteristics of the Kimberlite. Integrated geophysical methods have demonstrated remarkable effectiveness in Kimberlite detection, providing critical technical support for the indirect exploration of diamond deposits.
