Following a fireball and sonic effects the Barwell meteorite fell on December 24th 1965. It is an ordinary chondrite that broke up during its passage through the Earth's atmosphere. At least 44 kg of fragments have been recovered. Barwell is a village near Leicester, Leicestershire, England.
The Barwell meteorite is classified as an L6 meaning it has a low iron content (5-10%) and indistinct chondrules (round features) that have in many places have been metamorphosed under conditions to homogenise the pre-existing minerals (olivine and pyroxene mainly). Look in PPL to see a few remaining chondrules (rotation 1) and some relatively large blocky pyroxene crystals. In reflected light, metallic iron (silvery grey) and troilite (golden yellow) are clearly visible.
