湘中地区,产于泥盆系中的层控铅锌、黄铁矿床较多,潜在远景也较大。这些矿床具层控矿床的共同特点:矿体呈似层状、透镜状集中于一定层位中,空间分布与沉积相有关,矿石组分简单,脉石组分与围岩相近,蚀变不明显,矿区范围内一般无岩浆岩存在。据研究,这些矿床的形成,主要受地层层位、沉积相和长期活动的北东向断裂带的控制。主要成矿阶段为后生阶段,矿床成因多属多来源的沉积—再造矿床。区域地质概貌
In central Hunan, the stratabound lead-zinc and pyrite productions in the Devonian are more, and the potential prospect is also larger. These deposits have the common features of stratabound ore deposits: the ore body is stratified, the lens is concentrated in a certain horizon, the spatial distribution is related to the sedimentary facies, the ore composition is simple, the gangue composition is similar to the surrounding rock, and the alteration is not Obviously, there is generally no magmatic rock in the mining area. According to the study, the formation of these deposits is mainly controlled by the stratigraphic layers, sedimentary facies and long-term NE-trending faults. The main metallogenic stage is the epigenetic stage. The origin of the deposit is mostly sedimentary-reconstructed deposit. Regional geological overview
