摘要:
辽宁瓦房店地区是我国著名的金刚石矿产地之一,前人在该区做过大量的研究工作,但找矿方法一直没有突破。本文采用音频大地电磁测深法(AMT)对已知的金伯利岩矿区进行试验,探讨AMT技术在金伯利岩矿区深部探测的应用效果。针对30号金伯利岩岩管区布设了5条剖面,结果显示岩管呈低阻反映,异常明显。结合地质资料,初步推断该区断裂、成矿带和低阻异常展布特征,为在该区进一步开展矿产勘查提供基础资料,对今后瓦房店地区寻找隐伏的金伯利岩体具有重要意义,也为其他类似地区寻找隐伏金伯利岩提供新思路。
Abstract:
The Wafangdian area located in Liaoning Province is well known for its rich diamond resources. Many researchers have carried out scientific study here, but so far there has been no technological breakthrough made in prospecting methods. This report carried out an experiment test for audio-magnetotellurics(AMT)application in the well-known kimberlite field, and also explored the effect of AMT application in deep detection. Five sections were designed specifically in the No. 30 kimberlite pipe, and the AMT results show that the pipe is characterized by low resistivity and distinct anomaly. On the basis of the geological data, we can preliminarily infer that the area presents the distribution characteristics of fault structure, metallogenic belt and low resistivity anomaly. This will provide the fundamental information for further exploration of mineral resources, and be of the importance in searching kimberley rock mass in the Wafangdian. This study provides new ideas for searching concealed kimberlites in other similar areas.
