Alstonite, also known as bromlite, is a low temperature hydrothermal mineral that is a rare double carbonate of calcium and barium with the formula BaCa(CO 3) 2, sometimes with some strontium. Barytocalcite and paralstonite have the same formula but different structures, so these three minerals are said … See more Alstonite is triclinic, but appears pseudo-orthorhombic because of twinning. The space group is P1 or P1. Alstonite appears to have a superstructure based on paralstonite without long range order of the metal See more Simple crystals of alstonite are not known. The crystals are invariably complex twins formed by repeated twinning, and have the form of doubly terminated pseudo-hexagonal pyramids, like those of witherite but more acute. The faces are horizontally striated … See more Twinning in alstonite is ubiquitous, forming pseudohexagonal groups. The mineral has one imperfect cleavage and it breaks with an uneven fracture.
