甘肃敦煌白石滩南金矿地质特征及成因浅析

Geological Characteristics and Genesis Analysis of Baishitan South Gold Deposit in Dunhuang,Gansu

甘肃敦煌白石滩南金矿主要分布在塔里木板块的东端,北山陆缘活动带古生代柳园-俞井子裂谷带西段,该在漫长的地质发展历史中,经历了复杂的地质构造变动和岩浆活动,已发现金、铜、钨、铁等多种优势矿种,显示了良好的成矿潜力。白石滩金矿是近年来新发现的金矿,通过分析研究区域地质背景及矿床地质特征,探讨矿床成因,对找寻区域上同类型矿床具有重要的指示意义和现实意义。

The Baishitan South Gold Mine in Dunhuang,Gansu Province is mainly distributed at the eastern end of the Tarim Plate,in the western section of the Paleozoic Liuyuan Yujingzi Rift Belt of the Beishan continental margin.During the long history of geological development,it has undergone complex geological structural changes and magmatic activities,and has developed various advantageous mineral types such as cash,copper,tungsten,and iron,demonstrating good mineralization potential.The Baishitan gold deposit is a newly discovered gold deposit in recent years.By analyzing and studying the regional geological background and geological characteristics of the deposit,exploring the genesis of the deposit,it has important indicative and practical significance for searching for similar types of deposits in the region.
