Three lithologies occur in shocked achondrite EETA79001: Al, exotic irregular crystals and clusters of coarse-grained olivine (Fo81--55:CaO 0.2, Cr2O3 0.6, NiO 0.5 wt.%), low-Ca pyroxene (En82Wo2--En58Wo12), and low-Ti chromite (Cr2O3 59, FeO 27, TiO2 0.7 wt.%); A2 basaltic host to Al containing pyroxene (mainly pigeonite En67Wo12--En52Wo13), maskelynite (An61--55Or0.7), high-Ti chromite (some rimming low-Ti chromite), whitlockite, minor Cl-apatite, ilmenite, pyrrhotite, and mesostasis; and B, a homogeneous basalt containing augite laths (~En40--50Wo25--35) in a matrix of pigeonite-augite, maskelynite (An62--56Or1.2), ulv¿spinelilmenite intergrowth, whitlockite, Cl-apatite, and mesostasis. Mineral compositions indicate an oxidation state similar to that of shergottites. Lithology Al represents an unmetamorphosed cumulate that was disrupted and partly resorbed by a basaltic magma. Incorporation of low-Ca magnesian pyroxenes and olivine increased the Mg/Fe ratio of the basaltic magma responsible for A2, and resulted in abundant crystallization of pigeonite. Lithology B was generated from a distinct magma lacking fragments of Al. The parental spinel harzburgite of Al was not annealed, and is probably a near-surface igneous cumulate from a shergottite-type basalt. Ringwood (?) and majorite (?) were found in shock veins.
