While most meteorites have a smooth surface with no holes, some meteorites exhibit thin flow lines or thumbprint-like features called regmaglypts. All are igneous rocks crystallized from magma. Water Rich Meteorite Linked To Mars Crust For the first time, scientists recovered celestial meteorites that have a definitive link with an asteroid from space. Some scientists believe they formed in melted asteroids in a similar way to iron meteorites, where dense iron metal sinks toward the centre to form an iron core. It is only 50,000 years old and so well preserved that it has been used to study impact processes. If it is a red or brown streak, you probably have hematite. meteorite crystallised and how the concen-trations of nickel and iron changed as the meteorite cooled down.
