黔西南金矿区域成矿规律及成矿模式
|
摘要
本文对黔西南金矿成矿规律进行了深入研究,并获得了系统认识。黔西南金矿的成矿作用具有多期性和继承性,其中卡林型金矿的主成矿期为燕山期,土型金矿为卡林型金矿在第四纪表生环境中改造而成。多级区域构造对多级成矿单元有逐级控制规律。卡林型金矿床分布具丛聚性、方向性、等距性,并与古构造有关。矿体在多层次滑脱构造系统及拆离断层中呈有序分布,也在褶皱-断裂构造中呈有序分布。成矿元素组合及共伴生矿产也具一定的空间分布规律。与黔西南金矿相关的矿床成矿系列有两个,亚系列有四个。在上述认识基础上,为其建立了统一的区域成矿模式。
In this paper,it studied the regional metallogenic regularity of gold deposits in southwest Guizhou province,and obtains the systematic understanding. The mineralization is multiple phases and inheritable. The main metallogenic period of Kalin-type gold deposit is Yanshanian,and the earthen-type gold deposit was transformed from the kalin-type gold deposit in the supergene environment in Quaternary. The multilevel regional structures control the multilevel metallogenic units respectively. The distribution of the kalin-type gold deposits has the characteristics of clustering,direction and equidistant,and related to paleostructure. The ore bodies are orderly distributed in the multi-layered decollement system,and are also orderly distributed in foldfault structure. Metallogenic element assemblage and associated minerals also have certain spatial distribution regularity. There are two metallogenic series and four sub-series to the gold deposits in southwest Guizhou.Based on the above understanding,a unified regional metallogenic model is established.
