拉丁美洲大地构造轮廓、成矿区带和成矿系列
|
摘要
拉丁美洲是全世界矿产资源最丰富的地区之一。总结该地区的成矿地质背景、划分成矿区带、研究成矿系列将对进一步规划勘查和开发起到指导作用。在大地构造轮廓方面分成3个构造亚域,对次级构造单元的划分方案进行了探讨。在成矿区带划分方面,按5级成矿区带的划分方案,对一级成矿域和二级成矿省进行了划分,三级及其以下的成矿单元,对前人的划分方案作了扼要的比较。在成矿系列方面以大地构造演化为主导,以成矿作用和矿床类型为标志,将有内在成因联系的一系列矿床整合成一个成矿系列,并细分为成矿亚系列和成矿组合。
Latin America is one of the regions that have richest mineral resources in the world. In this paper, the authors have summarized the metallogenic geological setting of this region, divided the metallogenic zones, and studied the metallogenic series so as to guide the further planning and development. In this paper, the tectonic contours of the earth were divided into three tectonic domains,with a discussion on the secondary tectonic zones. As for the division of metallogenic belts, the authors classified the zone into primary metallogenic domain and secondary metallogenic province according to the five-stage metallogenic zone scheme. For the metallogenic units of level 3 and under level 3, the authors made a brief comparison with previous results. In terms of metallogenic series, the authors took the tectonic evolution as the guidance and the mineralization and deposit types as the indicators, collaborated the deposits that have inner connection into one series, and then divided them into sub-class metallogenic series and metallogenic assemblages.
