Barwell

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.

About this collection

The British Meteorites collection consists of meteorites that have fallen in Great Britain and Ireland and which are now preserved in museum collections. We have also included samples of the two known meteorite impact deposits in the UK.

The Natural History Museum in London offers more information about meteorites and meteorite categories and there is more information about its meteorite collections here.

Title
Refers to any word or phrase that appears in the individual rock names. Names are generally descriptive; they allow the user to searranite' as well as more speci?c names such as 'breccia'. However, the adjacent descriptiix captures a wider range of general words and phrases and is a more powerful search tool.

Accessory minerals
Minerals that occur in very low abundance in a rock. They are usually not visible with the naked eye and contribute perhapssver, they often dominate the rare elements such as platinum group metals.
Rock-forming minerals
Minerals that make up the bulk of all rock samples and are also the ones used in rock classi?cation.
Timescale
Selecting one or more period, for example 'Jurassic'.
Theme
A term used to group togge.g. the UKVM contains a 'SW England granites' theme that includes such rock types as granite, hydrothermal breccia, skarn, and vein samples).
Category
A general term used to label a rock sample. It is a useful way of grouping similar samples throughout a collection. Category names are often, but not exclusively, common rock names (e.g. granite, basalt, dolerite, gabbro, greisen, skarn, gneiss, amphibolite, limestone, sandstone).
Owner
The owner of the sample that appears in the collection. For example, NASA owns all the samples that appear in the Moon Rocks collection
