Ordinary chondrite, black and veined (H5; S3)
Fell, 10 September 1813, 9 hrs; 50 kg

A shower of stones fell after the appearance of a fireball accompanied by detonations. The larger stones included masses of 29.5, 10.9, and 7.9 kg which fell at Brasky, Faha, and Scagh, respectively. Olivine (Fa19) and orthopyroxene (Fs16) compositions are characteristic of the H-chondrite geochemical group. Mineralogically, olivine and low-Ca pyroxene account for roughly 70% of the meteorite with minor amounts of Fe-Ni metal (mostly kamacite), troilite, and feldspar. Accessory chromite, copper, phosphates, and, presumably, other minor silicates are also present.

A Pb,Th:He gas retention age of 3.02 Ga and cosmic-ray exposure (CRE) ages of 6.8 Ma (He,Ne) and 7.41 Ma (Cl-Ar) are reported. The CRE age is similar to many other H5 CRE ages, suggesting that the Limerick pre-impact meteoroid may have been involved in a collision that produced other H5 meteoroids which eventually reached the earth.

The H (relatively high in total iron) chondrites are the second largest group of ordinary chondrite falls and represent over 35% of well-classified, witnessed falls. Approximately half of the H-group chondrites are members of the H5 petrologic type H subgroup. Limerick was only the 8th H5 meteorite fall to be recovered of those now classified exactly as 'H5' chondrites. Limerick is also the 16th most massive of these 174 witnessed H5 falls (June 2017).

The Brasky mass has been held at Ireland's National Museum in Dublin with the Faha mass held at the University Museum of Oxford.
