Siderolites are stony-iron meteorites that are composed of both silicate minerals and iron-nickel alloys. These meteorites are also sometimes referred to as pallasites, which is a type of stony-iron meteorite that is characterized by its beautiful gem-like interiors. Other synonyms for siderolite include siderite, ironstone, and iron meteorite. There are several different types of siderolites, including octahedrites, hexahedrites, and ataxites, all of which are differentiated by their crystalline structures and iron content. Siderolites are extremely rare and valuable, and are often collected by meteorite enthusiasts and collectors. These fascinating relics of the cosmos provide a unique window into the formation and evolution of our solar system.
