Fact sheet


This single stone of 767 grams fell on 15th May 1991 in the village of Glatton, 15 km SSW of Peterborough, Cambridgeshire, England. It landed in the garden of Mr Pettifor who heard it crash through a hedge and found it, still warm, in a pit about 2 cm deep. The meteorite has a granular texture and was acquired for the nation by the Natural History Museum in London. 

The Glatton meteorite is classified as an L6 chondritic meteorite, meaning it has a low iron content (5-10%) and indistinct chondrules that have been metamorphosed under conditions capable of homogenising all mineral compositions. Look in PPL to see chondrules consisting of olivine and pyroxene crystals. Rotation 1 shows parts of three chondrules whereas rotation 2 shows a single, very indistinct chondrule and some blocky pyroxene and olivine crystals. The reflected light view reveals the location of the metallic iron in this sample (silvery grey mineral) and troilite (a golden yellow sulphide mineral).

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
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.

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.
Selecting one or more period, for example 'Jurassic'.
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.
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).
The owner of the sample that appears in the collection. For example, NASA owns all the samples that appear in the Moon Rocks collection
