Stony-iron meteorite - Wikipedia
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. [1]
Stony-Iron Meteorites: Their Origin, Classification, Pictures - Geology.com
What Are Stony-Iron Meteorites? As discussed in previous editions of Meteorwritings, iron meteorites are composed primarily of iron and nickel, and once formed part of the core of planets or large asteroids. Stones are the most abundant type of meteorite, and most once comprised part of the crust of bodies within the Asteroid Belt.
Types of Meteorites: Iron, Stone, Stony-Iron, Lunar, Martian - Geology.com
Stony-Iron Meteorites. The least abundant of the three main types, the stony-irons, account for less than 2% of all known meteorites. They are comprised of roughly equal amounts of nickel-iron and stone and are divided into two groups: pallasites and mesosiderites.
Stony iron meteorite | Meteoroid, Chondrite & Fusion | Britannica
Stony iron meteorite, any meteorite containing substantial amounts of both rocky material (silicates) and nickel-iron metal. Such meteorites, which are often called stony irons, are an intermediate type between the two more common types, stony meteorites and iron meteorites.
Types of meteorites - Natural History Museum
Stony-iron meteorites consist of almost equal parts iron-nickel metal and silicate minerals including precious and semi-precious gemstones. They are considered some of the most beautiful meteorites. There are two different types of stony-iron meteorites: pallasite and mesosiderite.
Pallasite - Wikipedia
The pallasites are a class of stony–iron meteorite. They are relatively rare, and can be distinguished by the presence of large olivine crystal inclusions in the ferro-nickel matrix.

Iron and stony-iron meteorites are fragments of a large number of asteroids that underwent significant geological processing in the early solar system.
Stony-iron meteorites – Buseck Center for Meteorite Studies
Stony-iron meteorites contain approximately even amounts of silicates and nickel-iron alloy, and are divided into two distinct groups: Pallasites and mesosiderites. Pallasites are believed to form between the silicate mantle, or outer shell, and molten metal core of a differentiated asteroid.
Stony iron meteorites - SpringerLink
Stony iron meteorites consist of approximately equal amounts by weight of silicates and iron—nickel metal plus troilite, although the ratio of silicate to metallic material can be quite variable. There are two major groups of stony iron meteorites, the …
