Usually named for the places where they are found, what are traditionally classified into three types as stony, iron and stony-iron?
Stony-iron meteorite Stony-iron meteorite Stony-iron meteorites or siderolites are meteorites that consist of nearly equal parts of meteoric iron and silicates. This distinguishes them from the stony meteorites, that are mostly silicates, and the iron meteorites, that are mostly meteoric iron. Stony-iron meteorites are all differentiated, meaning that they show signs of alteration. They are therefore achondrites. The stony-irons are divided into mesosiderites and pallasites. Pallasites have a matrix of meteoric iron with embedded silicates (most of it olivine). Mesosiderites are breccias which show signs of metamorphism. The meteoric iron occurs in clasts instead of a matrix. They are in the top
Stony Creek (Black Creek tributary) Stony Creek (Black Creek tributary) Stony Creek is a tributary of Black Creek in Luzerne County, Pennsylvania, in the United States. It is approximately long and flows through Hazle Township and West Hazleton. Its named tributaries include Cranberry Creek and Wolffs Run. Stony Creek is considered to be impaired by acid mine drainage and also has measurable concentrations of iron, aluminum, and manganese. The Llwellyn Formation and the Mauch Chunk Formation can be found near the creek. Land uses in its watershed include forested land and barren land. A reservoir has been constructed in the watershed and at least one
