Dunite may also form by the accumulation of olivine crystals on the floor of large basaltic or Picrite magma chambers.

For example, peridotites with well-formed olivine crystals occur mainly as layers in gabbroic complexes.

Layered peridotites are igneous sediments and form by mechanical accumulation of dense olivine crystals.

It is a pallasite-a type of stony-iron meteorite with striking olivine crystals.

The fracturing of olivine crystals and other features must be observed under a microscope with shock effects observed under polarized light.

When cut and polished, the meteorite showed beautiful yellowish olivine (peridot) crystals.

It consists of cm-sized olivine crystals of peridot quality in an iron-nickel matrix.

Pallasites are a type of stony-iron meteorite that when cut and polished show yellowish olivine (peridot) crystals.

Remarkably, many of the new specimens (about 20%) were found to contain olivine crystals and so revealed the silicated nature of the meteorite.

Due the heterogeneous structure of Seymchan, there are two types of specimens: with or without olivine crystals.
