The progress in the study of the Boroo gold deposit in Mongolia
摘要
Abstract
The Boroo gold deposit, located in northern Khentei gold ore belt, is the first hard rock gold deposit discovered in Mongo⁃lia, and its scale of mining and the gold production are also the largest (averagely 3.52g/t gold, with total produced gold reaching 66t) . The deposit is hosted in the Boroo fault, a nearly flat-lying fault zone. The total combined length of the mineralization zone (anoma⁃lous gold values≥100ppb) is more than 2500m, the width is at least 400m, and the thickness is locally as large as 100m. This area is underlain by granitoids of the Boroo Complex and metasedimentary rocks. Two main types of mineralization have been recognized in the Boroo gold deposit:the gold-sulfide type and the gold-quartz vein type. A comparison of the Boroo deposit with China ’s Jin⁃shan gold deposit shows that there exist many similarities between these two deposits, and hence the authors consider that the Boroo gold deposit is an orogenic gold deposit. Meanwhile, there is another large-sized gold deposit called Gatsuurt gold deposit 35km away from the Boroo deposit, which shares the same deposit type and equal ore reserves. On the basis of previous researches, the au⁃thors have made a detailed summarization in the aspects of production environment, geological characteristics, and genesis of the de⁃posit. This paper provides useful information for Chinese companies’prospecting for the same type gold deposits;in addition, three strategic targets in the adjacent areas of Boroo have been delineated.关键词
