Alloclasite, or (specific gravity of 5.91–5.95.[2]
It was first described in 1866 for an occurrence in Romania.[3] Its name is derived from Greek for "other" and "to break," in reference to its distinct cleavage which distinguished it from the similar appearing mineral marcasite.[4][2]
The mineral is monoclinic in the P21 space group.[5]
