Fact sheet


The Dundrum meteorite was seen to fall on August 12th 1865 after detonations ("like the shot out of a cannon") had been heard. It is an ordinary chondrite weighing 2.27 kg.

Dundrum is near Cashel in County Tipperary, Republic of Ireland.

The Dundrum meteorite is classified as an H5 (veined), meaning it has a high iron content (12-21%) and indistinct chondrules (round features consisting of olivine and pyroxene crystals). Look in PPL to see fragmented and distorted chondrules (rotation 1) and crystals of olivine (rotation 2). As this is not a polished section a reflected light view is not possible - however, look at the black areas in PPL to see the location of metallic iron and 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  
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.
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.
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
