Genesis and Metallogenic Regularities of Luodian Nephrite Deposit in Guizhou Province

Abstract:

The large nephrite deposit recently discovered in Luodian， Guizhou Province represents a major breakthrough in the exploration history of nephrite in China. Previous studies have shown that this deposit has obvious particularity and difference compared with other known nephrite deposit， both domestically and internationally. To reveal the new genetic type of the deposit， this paper analyzes the source of Si and Ca essential for mineralization. By integrating the geological characteristics of the mining area with the sources of metallogenic materials and the physicochemical conditions of mineralization， the deposit’s genesis was determined， and a metallogenic model was established. This provides a scientific basis for the rational exploitation of the Luodian nephrite deposit and supports mineralization prediction， exploration， and development of nephrite deposits in neighboring areas.
