Fact sheet

Appley Bridge

The Appley Bridge meteorite fell on 13th October 1914. Local residents saw the night sky illuminated and the following day the 15 kg meteorite was found in a farmers field (almost half a metre down). It is an ordinary chondrite. Appley Bridge is in Lancashire, England.

The Appley Bridge meteorite is classified as an LL6 meaning it has a low iron content (5-10%) and indistinct chondrules. The chondrules are so indistinct that they are difficult to see. Look in PPL to see crystals of pyroxene (rotation 1) and olivine (rotation 2). View in reflected light to see a few grains of metallic iron (silvery grey in colour) and many more grains of the golden yellow sulphide mineral troilite.

About this collection

This 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; there is more information about its meteorite collections here.

Category Guide
Title
Refers to any word or phrase that appears in the individual rock names. Names are generally descriptive; they allow users to search for broad terms like ‘granite’ as well as more specific names such as ‘breccia’. However, the adjacent descriptions of the specimens captures a wider range of general words and phrases and is a more powerful search tool.
Description
Refers to any word or phrase that appears anywhere in the descriptions of the specimens
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 together related samples that are not already gathered into a single Collection. For instance, there is 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
