| 中文摘要: |
| 万合永火山盆地位于大兴安岭南端，沽源-红山子铀成矿带的北东段，中生代火山活动非常频繁且强烈。利用可控源音频大地电磁测量和地面高精度磁法测量，共推断通过L11和L12线的断裂8条，二叠系基底自北西向南东逐渐抬升，侏罗系火山岩盖层逐渐变薄。通过两条测线对比，发现侏罗系盖层向北厚度变大。本文对万合永盆地的研究区进行了综合的线性构造及火山机构解译，根据推断的构造信息，并结合研究区已知矿床、矿化点(带)的矿化和分布特征，预测了铀找矿靶区4处，为下一步的矿产勘查提供依据。 |
| 英文摘要: |
| The Wanheyong Volcanic Basin located in the southern end of the Greater Khingan Mountains, in the north-eastern section of the Guyuan-Hongshanzi uranium metallogenic belt. Mesozoic volcanic activity is very frequent and intense. Using controllable source audio magnetotelluric measurement and ground high-precision magnetic measurement, it is inferred that there are 8 faults passing through the L11 and L12 lines. The Permian basement gradually rises from northwest to southeast, and the Jurassic volcanic caprock gradually becomes thinner. Through the comparison of the two survey lines, it is found that the thickness of the Jurassic caprock increases northward. In this paper, a comprehensive linear structure and volcanic structure interpretation of the study area in the Wanheyong Basin is carried out. Based on the inferred structure information, combined with the mineralization and distribution characteristics of known deposits and mineralization points (belts) in the study area, it is predicted there are 4 uranium prospecting target areas to provide the basis for the next mineral exploration. |
