拍品专文

This Martian meteorite consists of millimeter-size, compositionally zoned grains of abundant Ca pyroxene and minor olivine surrounded by a glass containing small spiky grains of additional minerals. The large grains formed during slow cooling in a magma chamber; the small grains and glass cooled rapidly during a volcanic eruption. This specimen is among the rarest samples on Earth; only 0.02% of known meteorites are nakhlites. The sample’s surface has been ablated by wind; little fusion crust remains.
