中文摘要: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。
Abstract:Based on the theory of metallogenic system, the authors studied the whole proces s of formation, transformation and preservation of uranium deposits in the Taosh an orefield in the aspects of metallogenic background and environment, ore-forming elements, ore_forming process, and metallogenic products as well as their pre servation. It is shown that uranium mineralization in Taoshan area is closely re lated to the Mesozoic-Cenozoic extensional tectonic-hydrothermal metallogenic sy stem. 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 dee pgoing researches on the development extent, temporal-spacial relationship, genetic relationship and reformation of various ore deposits in the uranium minerali zation network of this area.
