五台恒山地区是我国重要的银、锰、金及多金属成矿区.区内矿产与中生代岩体分布具有密切关系.而中生代岩体主要受断裂构造控制.因此,利用重、磁资料研究五台恒山地区的断裂构造、岩体分布及构造单元,为进一步划分成矿远景区提供地球物理依据.利用归一化总水平导数垂向导数(NVDR_THDR)技术推断研究区断裂分布,共划分断裂23条.其中一级断裂6条.二级断裂17条;利用剩余异常研究岩体的分布特征,共推断隐伏岩体34处。主要分布在五台山、恒山及灵丘一带:根据断裂和岩体的分布特征及重、磁异常场的分区特征,结合相关的地质资料,将研究区划分为11个构造区,主体走向为NE和NNE向.研究表明.NE向断裂对构造单元的展布和岩体分布起主要控制作用,并且岩体主要分布于五台山中部NE、NW及近EW向断裂的交汇处.同时位于不同构造单元的分界处.
The Wutai Hengshan area is an important silver, manganese, gold and polymetallic metallogenic area in China.The mineral resources in the area are closely related with the Mesozoic rock mass distribution.The Mesozoic rock mass is mainly controlled by the fault structure.Therefore, The fault structure, the distribution of rock mass and the tectonic units in the Taihangshan area provide the geophysical basis for the further division of the ore prospecting area.The normalized total horizontal derivative vertical derivative (NVDR_THDR) is used to deduce the fracture distribution in the study area and to divide the fault Of which one is fault 6. There are 17 secondary faults, and the remaining anomalies are used to study the distribution characteristics of rock mass, and a total of 34 hidden-rock masses are inferred. They are mainly distributed in the Wutai Mountain, Hengshan and Lingqiu areas. According to the distribution of faults and rock mass and the regional and regional characteristics of heavy and anomalous magnetic anomalies, the study area is divided into 11 tectonic zones with NE and NNE.Studies show that the NE trending faults play a major role in controlling the distribution of tectonic units and the distribution of rock mass, and the rock mass is mainly distributed at the intersections of NE, NW and near-EW faults in the central part of Wutai Mountain.At the same time, Division.
