Gold Mineralization and Genesis of Gatsuurt deposit in North Khentei gold belt, Central Northern Mongolia

Abstract

Gatsuurt deposit is one of gold deposits in the North Khentei metallogenic belt, the biggest gold productive province of Mongolia, and is located approximately 130 km north of Ulaanbaatar.This deposit consists of disseminated and vein type gold mineralization in early Devonian subvolcanic, early Paleozoic granitoid complex, and early Paleozoic meta-sedimentary rocks.
According to tectonic and geological setting, hydrothermal alteration, mineralogy and fluid inclusion study, Gatsuurt deposit is suggested as intrusion-related gold system.
