位于桂西北丹池成矿带上的大厂地区是一个以锡石——多金属硫化物为主的大型矿田。由一系列有规律分布、成因上紧密联系的大小矿区组成。多年来,矿区215地质队和科学院贵阳地化所等单位曾对控矿因素、矿床成因、成矿物质来源等进行过深入研究。本文主要讨论与龙头山生物礁有关的矿床成因。限于资料及手段,这里仅能提出一些粗浅看法。 The Dachang area, located in the Danchi metallogenic belt in western Guangxi, is a large-scale ore field dominated by cassiterite-polymetallic sulphides. By a series of regular distribution, genetically linked to the size of the mining area. Over the years, 215 geological teams in the mining area and the institute of Guiyang Geochemistry of the Academy of Sciences conducted an in-depth study on the ore-controlling factors, the genesis of the orebodies and the sources of metallogenic materials. This article focuses on the mineralization associated with the Longtoushan bio-reef. Limited to information and tools, here can only make some superficial view.
