Study on the metallogenetic regularity of gold deposits along Qinghe—Alatasi region in Altay of Xinjiang
摘要
Abstract
The Qinghe-Alatas region in Altay of Xinjiang is located on the southeastern margin of Altay orogenic belt,belongs to a zone of tectonic collision and accretion which exhibits complex regional tectonic evolution and frequent magmatic activity which provide favorable geological conditions for mineralization,and is an important polymetallic mineralization area in China.This paper carries out a detailed study on the stratigraphy,magmatic rocks,structures and typical geological characteristics of mineral deposits in the region,summarizes the metallogenic regularity based on its geological characteristics.Gold mineralization is mainly controlled by the Main Ebo fault zone and is spatially distributed in a strip-like pattern in the secondary faults on both sides of the fault zone.The gold deposits are classified into alteration rock type and quartz vein type based on their distance from the main fault zone,and their distribution characteristics show a trend of northwest convergence and southeast divergence.The degree of gold mineralization is closely related to factors such as sulfide content,alteration intensity and type of surrounding rocks,tectonic activity,and development degree of vein rocks.These findings provide important evidence for further understanding the gold resources in this region.关键词
