achondrite
Achondrite that fell in Sioux County, Nebraska. This eucrite has been broken open, revealing the distinction between its black, shiny, and smooth fusion crust and its light-colored interior.
Achondrite
An achondrite is a stony meteorite that is made of material similar to terrestrial basalts or plutonic rocks.

Achondrite Meteorite
Discovered at Reckling Peak, Antarctica, this type of meteorite is known as an achondrite. It has a basaltic composition and was probably formed when an asteroid melted about 4.5 billion years ago.
The surface material of Dembowska has been identified as being most consistent with a pyroxene and olivine-rich composition analogous to the pyroxene-olivine achondrite meteorites.
They make up about 95% of all the meteorites known to have fallen to Earth, and can be differentiated (achondrites) or non-differentiated (chondrites).
Very few asteroids, notably Vesta, are probably related to the rarest meteorite class of all: the achondrites. These asteroids appear to have an igneous surface composition like that of many lunar and terrestrial lava flows.
Stony meteorites are further classified as chondrites, achondrites, or carbonaceous chondrites based on their carbon content and texture.
Stony meteorites are one of the most abundant meteorite types, consisting largely of silicate minerals, divided into two groups named chondrites and achondrites.
