Abstract:Abstract: [Objective] Peridotite is an important mineral resource in China, which is widely used in building materials, refractory materials and fertilizer raw materials. Studying the origin, distribution and prospecting prospect of peridotite ore deposit is an effective way to solve the shortage of olivine resources in our country, and it is an important guideline for discussing the origin and prospecting direction of chromite ore deposit. [Methods] This paper summarizes the origin,distribution, mineral deposit types, development and utilization of peridotite in China by collecting and sorting out previous research data. [Results] According to the output of olivine, peridotite includes two main types of deposit: peridotite envelope type occurring in basalt and vein filling hydrothermal type occurring in peridotite. The main mineral areas of peridotite in China are Nanyang in Henan Province, Hebei Province, Jiaohe in Jilin Province and Shangnan in Shaanxi Province. Jiaohe olivine gem deposit in Jilin is the main source of olivine gem in China. The calc-magnesium-olivine deposit in Shangluo Mountain area at the border of Henan Province and Shaanxi Province has reserves of about 500 million tons with a grade of 44%. [Conclusions] The known resources of peridotite in China are not very rich, but the ore quality is good. As of 2022, China''s Ministry of Natural Resources statistics, the national reserves of 16008 million tons, the total amount of peridotite ores for fertilizer in the country is 2,492,200 tons, and the total amount of peridotite ores for refractory in the country is 17,766,100 tons. The olivine gem deposit in Jilin Jiaohe and Wanquan County of Hebei Province is an important olivine gem deposit because the olivine gem mine in Hebei Province has been closed. At the same time, the partial melting of peridotite is closely related to the enrichment of chromium, and the liquid phase immiscibility of the melt formed by partial melting of the depleted mantle leads to the formation of silicate magma and chromium-rich pulp. The study of peridotite is of great significance not only for the exploration of peridotite deposits, but also for the deposits with peridotite as the surrounding rock.
