| Metallogenic Regularity of Germanium in Yunnnan Province |
| Germanium (Ge) is a strategic mineral in China, and an advantageous mineral in Yunnan Province. There is a large reserve of Ge resources, a high degree of development and utilization, and a large space for prospecting in Yunnnan Province. The types of Ge ore deposits in Yunnan Province mainly include two types of coal-bearing type and carbonate hosting type germanium deposits. The coal-bearing germanium deposits are mainly distributed in Tengchong, Mangshi, Cangyuan, Lincang, Lancang and other regions in western Yunnan Province, and their formation ages are relatively concentrated in the Neogene time; the carbonate hosting germanium deposits are mainly distributed in Dongchuan, Huize, Yiliang, Ludian and other regions in northeastern Yunnan Province, and are symbiotic with lead-zinc deposit. The formation period of these deposits is generally recognized in the Triassic period. This paper comprehensively introduces the metallogenic geological conditions and spatial distribution characteristics of typical germanium deposits of above two types, summarizes the mineralization patterns of Ge resources, and proposes 23 prediction areas for Ge exploration in Yunnan Province. Meanwhile, it is necessary to strengthen the research on prospecting and comprehensive recycling of replacement resources in the deep and peripheral areas of existing Ge deposits, and to carry out prospecting exploration and target area optimization work for various prediction areas, in order to increase the storage of Ge resources in the old area and the prospecting breakthrough in the new area as soon as possible, so as to provide resources and technical support for a world-class Ge resource industrial base and national Ge resource strategic reserve demand. |
