Macroscopic Description - Roberta Score
Ten percent of the original fusion crust remains on LEW88005. Many large semi-rounded clasts, as large as 2 x 2 cm, are present. These clasts include mono- and poly-mineralic clasts, aphantic clasts and eucritic type clasts. Several areas are stained with oxidation. In hand specimen, LEW88005 closely resembles LEW85300, LEW85302 and LEW85303.
Thin Section Description (,11) - Brian Mason
The section shows a microbreccia of polycrystalline clasts in a fine-grained matrix of comminuted pyroxene and plagioclase. The clasts range up to 5 mm across, and are fine- to coarse-grained aggregates of pyroxene and plagioclase. Microprobe analyses show pyroxene compositions ranging fairly continuously from Wo1Fs59 to Wo42Fs25, with a limited range in En content (En31-43). Plagioclase compositions are in the range An88-93, with a mean of An92, Accessory grains of a silica polymorph, probably tridymite, were analysed. The meteorite is a monomict eucrite.
