Sarmientite
Sarmientite is a rare hydrated iron arsenate sulfate mineral with the chemical formula Fe^3⁺2(AsO4)(SO4)(OH) * 5H2O. It belongs to the Strunz classification 8.DB.35 and crystallizes in the monoclinic system. The mineral typically exhibits a yellow to brown color and a vitreous to pearly luster. It is relatively soft, with a Mohs hardness of approximately 2 to 2.5, and has a low to moderate density. Sarmientite is classified as a sulfato-arsenate mineral, and its physical properties are influenced by its complex hydration and the presence of both sulfate and arsenate anions in its structure.

Etymology

How to recognize it
Sarmientite can be identified by its low hardness, typically 2 to 2.5 on the Mohs scale, and its yellow to brown color. It has a vitreous to pearly luster and a low to moderate density. The streak is likely white or pale in color. Due to its rarity and softness, it is not commonly confused with other minerals, but its hydration and sulfate-arsenate chemistry make it distinct from more common sulfates or arsenates.
Trivia
Sarmientite is notable for its complex chemical composition, containing both sulfate and arsenate groups along with five water molecules. It is a rare mineral, with limited occurrences reported.
