| Metallogenic Geological Conditions and Tungsten-Polymetallic Ore Prospecting in Guidong-Rucheng Area, Hunan Province |
| In recent years, a number of tungsten polymetallic ore deposits were discovered in Guidong—Rucheng area, resulting in a remarkable breakthrough in the expansion of ore deposit type and ore deposit size. The ore deposits are of skarn type, altered granite type, structural alteration belt type, quartz vein type, greisen type, bedded type etc. In this area, strata are complete, rock layer thickness is huge, and tungsten mineral resource horizons occur in Sinian, Cambrian and Devonian strata. There exist in this area multi-cycle tectonic disturbance, well-developed structures, intense magmatic activities and large areas of complex granite bodies, especially the Yanshanian granites which are closely related to mineralization. Based on a description of the geological background, this paper deals with the characteristics of tungsten polymetallic ore deposits in this area, tentatively analyzes ore-forming geological conditions and, on such a basis, points out that there exist considerable ore-search prospects in this area. |
