| 摘 要： | 琼-粤西-桂东南成矿带含广西壮族自治区东南部分地区、广东省西南部分地区以及海南省全部。该区位于欧亚板块、印度板块和太平洋板块接合区。大地构造属于武夷云开岛弧系。本文以新的研究成果和找矿突破为基础,通过综合分析,在该地区划分新的重要成矿部署区带,并命名为琼-粤西-桂东南成矿带。本区成矿地质条件优越,矿产丰富多彩。目前已涌现像抱伦金矿、富湾铅锌银矿、大降坪硫铁矿为代表的一大批大型、超大型矿床。对本成矿带的矿床成矿特征进行了研究,划分了14个成矿系列,建立了成矿谱系,并对资源潜力进行了评价。研究区主要矿床类型为沉积变质型、热水沉积型、热液脉型、接触交代型、斑岩型和表生型。成矿受构造作用影响明显。在此基础上,部署了广东云浮地区金、银、铁矿重点远景区、广西陆川地区金银一般远景区、海南石碌铁、金矿一般远景区。为指导本区勘查工作提供了依据。

| Abstract: | Hainan- Western Guangxi Southeast Guangxi metallogenic belt comprises Southeast Guangxi, Southwest Guangzhou and Hainan island. This area is the conjuncture zone
of Euraasia, India and Pacific plates. Based on new research result and exploration progress, a new metallogenic belt was generated and named after Hainan West Guangxi and Southeast Guangdong metallogenic belt. This belt is with favorable ore- forming environment and various minerals.The characteristics of typical deposits were summarized and
14 mineralisation series were generated with ore deposit spectrum. The mineralization potential in this belt was also being assessed. The main deposit types are sedimentary metamorphic type, hydrothermal sedimentary type, hydrothermal vein type, contact metasomatic type, porphyry type and supergene type. Mineralization process was controlled by structures. Based on the research, Au- Ag- Fe- key prospective zone of Yunfu in Guangdong, Au- Ag- prospective zone of Luchuan area in Guangxi and Fe Au prospective zone in Hainan were generated, which could support mineral exploration in this belt. |
