西南大面积低温成矿域:研究意义、历史及新进展

A Study on the Large-Scale Low-Temperature Metallogenic Domain in Southwestern China—Significance,History and New Progress

我国西南大面积低温成矿域是目前世界上公认的2个大面积低温成矿域之一,其面积之大(约100万km2)、包含的矿种之多(Au、Hg、Sb、As、P、Pb-Zn、Ag以及萤石、冰洲石、水晶、分散元素等)、矿床组成和组合之复杂全球罕见,是我国重要的Au、Hg、Sb、As、Pb-Zn、Ag以及多种分散元素生产基地。国内外学者对该成矿域进行了近30年的研究工作,取得了大量高水平研究成果,同时也存在许多有待深入研究的科学问题。本文回顾了我国西南大面积低温成矿域的研究历史,总结了各研究阶段的主要研究内容、主要研究成果和存在的主要科学问题,同时介绍了近年来我国西南大面积低温成矿域研究新进展。

The large-scale low-temperature metallogenic domain in southwestern china is one of the two large-scale low-temperature metallogenic domains in the world. As a unique region, this domain is characterized by its large area （about one million square kilometers） , many kinds of mineralization （Au, Hg, Sb, As, P, Pb-Zn, U, Ag, fluo- rite, ealcspar, quartz., and dispersed elements）, and complicated compositions and associations of ore deposits. It is also an important production base on Au, Hg, Sb, As, P, Pb-Zn, U, Ag and dispersed elements in China. Many scholars have carried out the research works in this area and acquired a great deal of research results in recent 30 years, however, it also exists some unsolved scientific puzzles. This paper not only synthetically analyzes the research history, the research content in different stages, the research achievements and the scientific problems, but also de- scribes the new progresses on the large-scale low-temperature metallogenic domain in southwestern china in recent years.
