The nephrite described in this study was sourced from the Zhengwei area, Dikou Town, southeast of Jian’ou City in northern Fujian Province. Tectonically, the mining area lies within the junction of the eastern and western Cathaysia blocks, which belong to the Yanping–Nanshan Early Paleozoic Mamianshan accretionary complex, which contains pelagic siliceous rocks. The investigated nephrite originates from the accretionary complex belt, which is exposed as an NE-trending wedge in the Jian’ou area. This complex consists of quartzite, diopsidite, marble, and tremolite rock, occurring as mixed lithologies with widely distributed low-grade metamorphic clastic rocks and metamorphosed carbonate blocks.
