Abstract

Five gold deposits (mineralization) were found in the study area by means of geological mapping, soil geochemical survey and trough exploration engineering. The ore-bearing lithology is mainly metamorphic feldspar sandstone of the Upper Carboniferous Benbatu Formation, and the gold (mineralization) body is controlled by both structural factors and stratigraphic factors of the Upper Carboniferous Benbatu Formation. The genetic type is preliminary concluded to be volcanic hydrothermal type, and the metallogenic age is late Variscan. In this paper, by studying the geological characteristics and metallogenic geological conditions of the gold orebody in the area, a regional prospecting model has been established, which is of great significance to better guide the prospecting work of similar gold deposits in the area and the region.

Highlights

  • The research area is located 220 km northwest of Bayanhot Town, the government seat of Alxa Zuoqi, within the territory of Tamusubraga Town, Alxa Youqi, Inner Mongolia Autonomous Region of China

Summary

Introduction

The research area is located 220 km northwest of Bayanhot Town, the government seat of Alxa Zuoqi, within the territory of Tamusubraga Town, Alxa Youqi, Inner Mongolia Autonomous Region of China. The study area is located in the Ejinaqi-hinggan mountains proterozoic era, variscan, Yanshanian of Cu, Pb, Zn, Au, Ag, Gr, Nb as a mining area, Wuliji-Xilinhaote proterozoic era, variscan, Yanshanian of Cu, Fe, Gr, Au, Fluorite metallogenic belt [1] [2] [3] [4]. The discovered gold deposits in the vicinity of the study area include Zhulazhaga gold deposit and Chaganchulu gold deposit, which indicate that this area has a good. By studying the geological characteristics and metallogenic geological conditions of the gold orebody in the area, a regional prospecting model has been established, which is of great significance to better guide the prospecting work of similar gold deposits in the area and the region
