摘要
毕家湾铅锌矿床位于西成矿田的南带中部-毕家山大型铅锌矿床的西延段,为一小型热水沉积-改造型铅锌矿床。该矿床赋矿地层为中泥盆统西汉水群第六岩性段第三岩性层的(Dx3-16)及(Dx3-36)两个亚层,赋矿构造为毕家山背斜,含矿岩性主要为硅化结晶灰岩或硅化大理岩。对其矿床地质特征和成矿规律进行了浅析和初步归纳研究。
Bijiawan pb-zn deposit is a small hot-water sedimentation-modified pb-zn deposit located in the middle of the south belt of the western ore-forming field and the western extension of the large pb-zn deposit in bijiashan. The ore-bearing strata of this deposit are the third lithosphere and two substrata of the sixth lithosphere in the west han dynasty of the middle devonian , the ore-bearing structure is the bijiashan anticline, and the ore-bearing lithology is mainly silicified crystalline limestone or silicified marble. In this paper, the geological characteristics and metallogenic rules of the deposit are analyzed and preliminarily summarized.
