南秦岭矿带旬北地区铅锌热水沉积成矿与钠长石特征分析

South Qinling Belt Ten-Day Lead-Zinc Mineralization and Hydrothermal Deposition Characteristics of Albite

南秦岭多金属成矿带蕴藏有丰富的铅锌金属矿产,是秦岭成矿带的重要组成部分。上世纪80年代,随着热水沉积成矿理论的引入,通过对容矿岩石的深入研究,人们提出了矿床同生热水沉积的认识,并取得了重大突破。陕西省地矿局第一地质队在这一理论指导下,在南秦岭旬阳盆地下古生界志留纪地层中相继发现了一批中小型铅锌矿床,自2001年开展的国土资源大调查项目《陕西旬北地区铅锌矿评价》以来,在旬阳长沙—白河黄石板一带发现长近百公里的钠长石岩带,分布于早古生代志留系地层中,岩石类型多样,热水沉积特点明显,与铅锌矿关系密切。

South Qinling polymetallie ore deposits are rich with zinc metal mineral, is an important part of Qinling Cheng belt of .80 years, with the introduction of the theory of hydrothermal sedimentary mineralization, rock by ore-depth study of people made a deposit with the deposition of raw water awareness and achieved a major breakthrough. Shaanxi Geological and Mineral Bureau of the first team under the guidance of this theory, in the South Qinling Xunyang Basin Paleozoic Silurian strata have been found a number of small lead-zinc deposits, carried out since 2001, land resources survey project ＂evaluation of lead-zinc mine in northern Shaanxi late＂ since the Xunyang Changsha - found along the White River Yellowstone board hundred kilometers long albitite belt, located in the Early Paleozoic Silurian strata, diverse rock types, sedimentary characteristics of hot water significantly, and lead and zinc are closely related.
