solualueita

Solualueita is a rare mineral species, first discovered in 2018. It is named after the Solu River in China, where it was found. Solualueita is a complex phosphate mineral with the chemical formula (NH4)2Ca(SO4)2(PO4)2·12H2O. It crystallizes in the monoclinic crystal system and typically forms as prismatic crystals or granular aggregates.

The mineral is characterized by its distinctive optical properties, exhibiting a strong pleochroism and a high refractive index. It is translucent to transparent, with a white to colorless streak. Solualueita has a Mohs hardness of approximately 3.5 and a specific gravity of about 2.3.

Solualueita is found in low-temperature, evaporitic environments, often associated with other sulfate and phosphate minerals such as gypsum, anhydrite, and apatite. Its occurrence is limited to a few locations worldwide, including the type locality in China and a few other sites in South America and Africa.

The mineral is of interest to mineralogists due to its unique chemical composition and crystal structure. It is also studied for its potential applications in various fields, including materials science and geochemistry. However, its rarity and limited availability make it a challenging subject for further research.

Solualueita is not currently recognized as a valid mineral species by the International Mineralogical Association (IMA). Its status is under review, and it may be reclassified or discarded based on ongoing studies. The mineral's classification is a subject of ongoing debate among mineralogists.
