广东省高潭幅调查区矿体地质特征与成矿条件分析

Analysis of Mineral Geological Characteristics and Metallogenic Conditions in Gaotan Survey Area,Guangdong

广东省高潭幅调查区属莲花山锡铜多金属成矿带的核心区域,地质构造复杂。通过对调查区开展野外地质调查,研究地质特征与典型矿点,分析成矿条件。结果表明,区内矿床、矿点在空间上沿莲花山断裂带作北东—南西向分布,除产在侵入岩内接触带外,其它均在外接触带的上三叠统—下侏罗统地层,与三叠—侏罗系地层的关系密切。区内北东向构造发育,控制了成矿母岩的形成和分布,同时为成矿元素富集提供导矿条件或容矿空间。高潭幅调查区具有优越的成矿地质条件,锡多金属矿床的找矿潜力较大。

The Gaotan survey area in Guangdong Province is the core area of the Lianhuashan tin-copper polymetallic metallogenic belt with complex geological structures.Through the field geological survey of the survey area,the geological characteristics and typical ore spots are studied,and the metallogenic conditions are analyzed.The results show that the deposits and ore points in the area are spatially distributed along the Lianhuashan fault zone in the northeast-southwest direction.In addition to the occurrence in the contact zone of the intrusive rock,the other Upper Triassic-Lower Jurassic strata in the external contact zone are closely related to the Triassic-Jurassic strata.The development of NE-trending structures in the area controls the formation and distribution of ore-forming parent rocks,and provides ore-conducting conditions or ore-accommodating space for the enrichment of ore-forming elements.The Gaotan survey area has superior metallogenic geological conditions,and the prospecting potential of tin polymetallic deposits is great.
