Babingtonite is a calcium and iron-rich mineral that is commonly found in igneous and metamorphic rocks. It is known for its black, prismatic crystals that are often confused with other minerals. However, there are several synonyms for babingtonite that can help geologists and mineral collectors identify it correctly. These synonyms include ferroan epidote, sideromelane, and neptunite. Ferroan epidote is a green and black mineral that is similar to babingtonite in chemical composition and crystal structure. Sideromelane is a glassy, dark brown mineral that is often found in volcanic rocks. Neptunite is a black mineral that is commonly found alongside babingtonite in metamorphic rocks.
