Yanomamite
Yanomamite is a rare phosphate mineral with the chemical formula indium arsenate dihydrate. It belongs to the orthorhombic crystal system and is classified in the Strunz system as 8.CD.10 and in the Dana system as 40.4.1.5. This mineral is characterized by its unique composition, which includes indium, arsenic, oxygen, and water molecules. It typically exhibits a vitreous luster and may display a range of colors depending on impurities. Yanomamite is a hydrated arsenate mineral and is part of the broader group of phosphate and arsenate minerals.

Yanomamite is a hydrated arsenate mineral and is part of the broader group of phosphate and arsenate minerals.
Etymology
Yanomamite is named after the Yanomamis, an indigenous people of the Amazon. The mineral was approved by the International Mineralogical Association (IMA), but no specific discovery year is provided in the facts.
How to recognize it
Yanomamite can be identified by its orthorhombic crystal system and its chemical composition, which includes indium and arsenic. Specific physical properties such as hardness and density are not provided in the facts, so identification may rely on chemical analysis. Its vitreous luster and potential color variations can aid in distinguishing it from other similar minerals.
Trivia
Yanomamite is notable for its inclusion of indium, a relatively rare element. It is a hydrated arsenate mineral, which is an unusual combination in the mineral world. The mineral is named after the Yanomamis, an indigenous group, which is a unique and culturally significant aspect of its nomenclature.
