The main types of magmatism gold deposits and their mineralization in Gansu Province
摘要
Abstract
As one of the provinces with large gold resources,Gansu Province has various types of gold ore mineralization and complex metallage,among which magmatic metallogenic is one of the main metallogenic mechanisms of gold deposits,and the prospecting research idea of tectonic-magmatism-metallogenic is more suitable for magmatic gold deposits.The magmatic rock province of Gansu Province can be divided into 10 tectonic magmatic rock belts,which are mainly Beishan tectonic magmatic belt,Qinling-Dabie tectonic magmatic belt,Tarim tectonic magmatic belt,Qilian Mountain tectonic magmatic belt,Altyn tectonic magmatic belt,North Qinling tectonic magmatic belt,etc.,these areas are also relatively concentrated areas of gold deposits,and the main types of magmatic gold deposits are magmatic deposits,contact metasomatic deposits,porphyry deposits,magmatic hydrothermal deposits and volcanic rock deposits.Combined with the division of tectonic magmatic rock belts and their main characteristics and the distribution of gold deposits in Gansu Province,this paper focuses on the analysis and study of the temporal and spatial distribution characteristics of magmatic gold deposits and magmatic rocks,the mineral-forming sources and physicochemical conditions of the main types of gold deposits in the Beishan tectonic magmatic belt and the Qinling-Dabie tectonic magmatic belt,summarizes the ore control factors,and proposes the main magmatic rock types,spatial ranges and technical methods that are conducive to gold prospecting.关键词
