Name:
Zheshengite is named in honor of Chinese mineralogist Zhesheng Ma (born 1937), a former professor at the China University of Geosciences (Beijing). She conducted extensive mineralogical research in the Dongchuan Copper ore field and was the first to describe tangdanite (formerly known as “clinotyrolite”), a new mineral discovered in that region.
The Zn-, or rather ZnZn-analogue of cuprozheshengite. An (ordered?) As-enriched analogue of dongchuanite.
A rare example of As-P separation into different structural positions.
A rare example of As-P separation into different structural positions.
