EMG50XXX: Together with the spectacular carlhintzeites discovered in the important Dachang find of March 2025, we have been able to confirm, thanks to the detailed analysis of the samples, the presence of Gearksutite. In the case of this particular piece the Gearksutite, white in color, appears associated with yellow Creedite crystals.
Gearksutite is a rare species, without reference specimens considered “spectacular” in classical mineralogy. For this reason, the presence of well-formed, intensely yellow Creedite not only enhances the aesthetic appearance of the specimen, but also provides a mineralogical framework to better appreciate this very little-known species.

Geologically, the area consists of thick Paleozoic limestone and dolomite sequences affected by strong faulting and fracturing, which provided pathways for hydrothermal fluids rich in sulfides, antimony, and volatile elements. These processes produced mineralized pockets and fissures where Carlhintzeite developed together with other uncommon species such as Gearksutite.
