A black mineral composed of manganese oxides and sometimes water, commonly found as a coating in rocks and valued as an ore of manganese.
From Greek asbole (soot) plus the mineral suffix -ite, a standard ending for minerals. This became the most widely adopted name for this mineral variety in modern geological science.
Asbolite finally became the standard name because the -ite ending was already used for hundreds of minerals, creating a consistent system—it's like how 'dioxide' tells you exactly what you're looking at, -ite names helped scientists organize the mineral world!
