Fact sheet

Killeter

Following the sound of detonations, the Killeter meteorite fell as a shower of stones in the early hours of April 29th 1844. A total mass of 140 g was recovered.

Killeter is a village in County Tyrone, Ireland.

The Killeter meteorite is classified as an H6 (veined) chondritic meteorite meaning it has a high iron content (12-21%) and distinct chondrules (olivine and pyroxene mainly). Chondrules are thought to have formed from the condensation of hot gases in the solar system around 4.6 billion years ago. In the hand specimen these chondrules are almost impossible to see. Instead it is the rusty alteration haloes around metallic iron and sulphide minerals that are most obvious.

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.

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

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
