Zhangpeishanite is a mineral named after Zhang Peishan (Chinese: 张培善), a Chinese mineralogist at the Institute of Geology of the Chinese Academy of Sciences, in recognition of his contributions to studying the mineralogy Bayan Obo deposit, where the mineral is mined. The Bayan Obo deposit is also known for being a world class deposit. The mineral got approved by the IMA in 2006 but was published two years after its approval.[2] The mineral consists of barium chloride fluoride.[3]
