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
Carbonate rock existing rock grains together or it can fill fractures. Karst topography and caves develop in carbonate rocks because of their solubility in dilute acidic groundwater. Cooling groundwater or mixing of different groundwaters will also create conditions suitable for cave formation. Marble is the metamorphic carbonate rock. Rare igneous carbonate rocks exist as intrusive carbonatites and even rarer volcanic carbonate lava. Carbonate rock Carbonate rocks are a class of sedimentary rocks composed primarily of carbonate minerals. The two major types are limestone, which is composed of calcite or aragonite (different crystal forms of CaCO) and dolostone, which is composed of the
