Ordinary Chondrite, polymict breccia (H5,br)
Fell Jan 1, 1907; 0.877 kg.
After detonations, a small meteoritic stone was recovered ~13 km S of Leighton. The bulk of the stone has characteristics of an H chondrite [olivine composition (Fa~20) and orthopyroxene (variety, 'bronzite')]. However, darker regions have a very varied compositional range (Fa5βFa40). In addition, a CM inclusion and some very small microliths add mineralogical diversity to what is a relatively small meteorite.
The main mass has been held by the Smithsonian National Museum in Washington, DC.
