Humodetrinite
Humodetrinite is a rare and poorly characterized mineral that belongs to the phosphate group. It was first identified in 1966 at the type locality of the Humodete mine in the Czech Republic, though its occurrence remains limited and debated among mineralogists. The mineral’s name derives from its association with the Humodete locality and its chemical composition, which includes elements like aluminum, calcium, iron, and phosphorus.
Chemically, humodetrinite is described as a complex phosphate, with a general formula often approximated as CaAl₃(PO₄)₂(OH)₃·H₂O,
Due to its rarity and ambiguous classification, humodetrinite has not been widely studied. Some researchers question
Given its limited occurrence and scientific ambiguity, humodetrinite holds minimal commercial or industrial significance. It remains
