New Concord Meteorite - fusion crusted individual (OSU public display, Orton Geology Museum, Ohio State University, Columbus, Ohio, USA).

Chondrites are the most common type of meteorites that fall to Earth. Chondrite classification is moderately complicated, and considers isotopic, chemical, mineralogical, textural, metamorphic, and weathering factors. Chondrites are derived from bodies in the Asteroid Belt that never underwent differentiation. That is, the parent bodies never experienced a heating event sufficient to produce a core, mantle, and crust.

All chondrites contain spherical to subspherical to somewhat irregularly shaped structures called chondrules. Chondrules are composed principally of mafic minerals (olivine and pyroxene). Chondrules are nearly the oldest materials in the entire solar system. Chondrites subjected to significant thermal metamorphism some time in their history have chondrules that are partially to almost completely recrystallized.
