Super Large Beryllium - Tin - Tungsten Rare Metal Deposits Discovered in Tibet

According to reports, recently from the China Geological Survey was informed that scientists from the China Geological Survey Chengdu Geological Survey Center in Tibet Himalaya metallogenic belt Zhaxi Kang mine area south of the fault that hole that identifies large gneiss dome structure, The highly differentiated pale granite within the dome has multistage intrusive features, and a large skarn-type beryllium-tin-tungsten rare-metal ore body is found on the edge of the dome. Through the sparse surface engineering control, a newly discovered beryllium-tin-tungsten rare metal orefield was submitted to a very large scale, revealing that in addition to the lead, zinc, gold and antimony minerals in the Himalayan metallogenic belt in Tibet, beryllium, tin, tungsten Other rare metal minerals also have great potential. This finding is of great significance to re-recognize the mineralization of the Himalayan metallogenic belt and guide the prospecting of the area.

 

According to reports, the newly discovered deposits in the Kunnandong area in the southern Zhaxikang ore district are mainly beryllium with symbiotic tin and tungsten with associated beneficial components such as Se-Ru-niobium-tantalum, lead-zinc-copper and gold-silver. Preliminary investigation and evaluation and research results reveal that the Kunlun hole beryllium polymetallic deposit belongs to the skarn type. The ore body is mainly produced in the outer contact zone of skarn or skarnized marble. The beryllium polymetallic ore deposit is in the layer Like or laminar output, stable layer, uniform thickness changes, the beryllium-containing minerals are mainly silicon beryllium, hydroxyapatite, followed by the fragrant stone, the metal minerals are mainly cassiterite, scheelite, sub-yellow Copper, galena, pyrite and so on.

 

Although abundant beryllium resources in our country, large independent beryllium resources and poor resource endowments are mainly associated with such minerals as lithium, niobium and tantalum. The average grade of ore deposits is much lower than that of other countries. The first discovery of the superlarge beryllium rare metal deposit in the fault zone of the Tazhikang deposit in southern Tibet has important theoretical and practical significance. First, the newly discovered minerals and types belonging to the Himalayan metallogenic belt in Tibet, have huge scale and potential, revealing the tip of the iceberg of the large-scale metallogenesis of the Pleistocene granite in the Himalayas metallogenic belt and promoting the re-understanding of the Himalayan belt mineralization Belt mineralization and prospecting potential. Second, a new prospecting window was opened to explore new prospecting areas and prospecting space. It is confirmed that the Himalayan metallogenic belt may become a new beryllium-tungsten-tin resource-rich area in China, which will stimulate the regional prospecting and accelerate the western part of China The construction of a new rare metal base is of great significance. Third, the establishment of the mineral prospecting area in Tibet.
