Anthraconite is a black limestone made of calcite and bitumen. It is also known as “stinkstone” or “swinestone.”. Bitumen is that black, sticky tar that is mixed with sand and pebbles to make asphalt road surfaces, though some people use the word “asphalt” interchangeably with “bitumen.”.Limestone is usually a biological sedimentary rock, forming from the accumulation of shell, coral, algal, fecal, and other organic debris. It can also form by chemical sedimentary processes, such as the precipitation of calcium carbonate from lake or ocean water. Table of Contents What Is Limestone?
