摘要
文章以成矿系统为理论基础,从成矿背景和环境、成矿要素、成矿作用过程、成矿产物及其保存等方面阐述了桃山矿田铀矿床形成-变化-保存的全过程。研究表明,桃山地区铀成矿与中新生代伸展拉张构造-热液成矿系统密切相关,在此背景下,多因耦合、临界转换是成矿作用的主要机理。文章在对本区铀矿化网络各类矿床的发育程度、时空关系、成因联系以及被改造情况等进一步研究的基础上,分析和探讨了桃山矿田下一步的找矿方向。
Based on the theory of metallogenic system, the authors studied the whole process of formation, transformation and preservation of uranium deposits in the Taoshan orefield in the aspects of metallogenic background and environment, ore-forming elements, ore-forming process, and metallogenic products as well as their preservation. It is shown that uranium mineralization in Taoshan area is closely related to the Mesozoic-Cenozoic extensional tectonic-hydrothermal metallogenic system. In such a background, coupling of many factors and criticality transition seem to constitute the basic ore-forming mechanism. Further ore-prospecting orientations in the Taoshan orefield are discussed in this paper on the basis of deepgoing researches on the development extent, temporal-spacial relationship, genetic relationship and reformation of various ore deposits in the uranium mineralization network of this area.
