Arsenopyrite
Definition
A masculine or neuter variant form used alternatively in technical literature to designate the iron sulfarsenic mineral (FeAsS). This crystalline compound from the sulfide class represents the most important and widespread natural source of arsenic, exhibiting an opaque metallic luster, a steel-grey color, and a monoclinic or orthorhombic crystal structure. It is frequently associated with hydrothermal deposits of gold, copper, and tin, releasing a strong garlic odor when struck or intensely heated.
