拆离构造与成矿作用

拆离构造是当前地学中的研究热点,对拆离构造的研究不仅具有重大的理论意义,而且更具有重要的经济意义。文中除对拆离构造的研究现状、含义、特征、形成机制和理论意义简要综述外,还就拆离构造对油气、煤及金、银、铜、铝、锌、铁等内生金属矿产的控制作用,作了重点论述,最后应用拆离构造控矿理论对我国华南地区铀矿田控矿构造进行了反思,提出了笔者的粗浅看法,以达启发思路、抛砖引玉,为扩大老矿区开辟新基地,为找大矿、找富矿提供地质构造依据。

DECOUPLING STRUCTURE AND METALLOGENESIS

The decoupling structure is, at present, a hot spot for the study in geoscience. A study on the decoupling structure is not only of great theoretical significance, but also of more economic importance. This paper briefly discusses the study of the decoupling sturucture in terms of its present status, implication, characteristics, formation mechanism and theoretical significance, in addition, with emphasis on the expounding of the decoupling structure over endogenic metallic deposits such as oil and gas,coal,gold,silver,copper,lead,zinc and iron etc. At last reconsideration is made of the ore control theory of the decoupling structure to the ore control structure in the uranium ore field in South china. The author proposes a superficial idea in order to provide a basis of geological structures for expanding old mining areas, opening up new areas(bases), and prospecting for large and rich uranium deposits.
