New nephrites reported in this study were collected in the Mengshan area (GPS: 114°54′–57′ E, 28°02′–05′ N) of Xinyu County, Jiangxi Province. This area is located in the eastern segment of the Qinhang Metallogenic belt, which was formed by the collision and splicing of the two ancient continents, namely the Yangtze and Cathaysia blocks, during the middle and advanced stage. The Mengshan composite pluton consists of Triassic granites (~217 to ~236 Ma) and Jurassic-Cretaceous dikes (~135 Ma and ~142 Ma). Xinyu nephrite occurs in the southeastern part of the Mengshan composite pluton, located in the contact zone of the Permian Maokou Formation with the pluton. Geological information shows that the lower part of the Permian Maokou Formation is cryptocrystalline limestone, calcareous limestone interbedded with muddy limestone, and the upper part is dark grey cryptocrystalline structural limestone interbedded with calcareous mudstone.
