    MAC02522

Macroscopic Description: Kathleen McBride
40% of the exterior is covered with a brown/black, slightly shiny, rough fusion crust. The exposed interior is dark gray. The interior reveals a moderately hard tan/gray matrix with dark gray clasts.

Thin Section (,3) Description: Tim McCoy, Linda Welzenbach
The section consists of a coarse-grained (0.5-1 mm) basalt composed of pyroxene and plagioclase, with minor SiO2 and oxides. The meteorite has been extensively shocked, producing mosaicism in the pyroxene and undulatory extinction in the plagioclase. Mineral compositions are intermediate pyroxene ranging from Fs51Wo12 to Fs38Wo30 (Fe/Mn ~30) and plagioclase of An87-90. The meteorite is an unbrecciated eucrite.
