Black Chasm Cave Black Chasm Cavern are derivative of the marble bedrock, containing primarily calcium or calcium carbonate (CaCO3). There are a variety of formations in Black Chasm Cavern, including stalactites, stalagmites, columns, flowstone, draperies, ribbons, angel's wings, cave bacon, soda straws, helictites, false floors, and others. Black Chasm Cavern is home to amphipods, which live in the lakes of the cave. The amphipods are adapted to life without light, having no pigmentation or eyesight. Also living within the cave, and adapted to total darkness, is the Banksula grubbsi arachnid. Related to the harvestman, the Banksula grubbsi has a multi-segmented body that appears
Amorphous calcium carbonate to be stable in ambient conditions for up to 3 weeks with most of its porosity retained. Bioavailability: Since 2013 a company named Amorphical Ltd. sells an ACC dietary supplement. Calcium carbonate is being used as a calcium supplement worldwide, however, it is known that its bioavailability is very low, only around 20–30%. ACC is roughly 40% more bioavailable than crystalline calcium carbonate. Drug delivery: Due to the ability to tune the size and morphology of the amorphous calcium carbonate particles (as well as other calcium carbonate particles), they have huge applications in drug delivery systems. Highly porous ACC showed
