caption_attribution_description: English: A slice of the Esquel meteorite. This type of meteorite is from the core-mantle boundary of an ancient planetoid that was smacked apart billions of years ago. The metal is iron/nickel core material and the crystals are peridot from the mantle area. At the interface, they mix together as you can see. This piece is from my collection. Español: Un pedazo del meteorito Esquel. Este tipo de meteorito es el límite entre el núcleo y el manto de un planetoide antiguo que se desprendio miles de millones de años atrás. El metal es de una materia de hierro/níquel y los cristales son peridoto de la zona del manto. En la interfaz, se mezclan como se puede ver. Esta pieza es de mi colección.
context_page_description: 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. Mesosiderites are breccias which show signs of metamorphism. The meteoric iron occurs in clasts instead of a matrix.
  They are in the top rank of all Meteorite classification schemes, usually called "Type".

  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 rank of all Meteorite classification schemes, usually called "Type".
