Macroscopic Description: Kathleen McBride
This aubrite is extremely altered and is very rusty inside and out. It has small thin patches of fusion crust that comprise less than 5% of the surface area. It is very friable and crumbles easily. QUE97348 contains mm-sized inclusions.

The section consists of mm-sized enstatite grains (Fs0.1), reasonably abundant (10% or more?) feldspar of variable composition (An4-35), Si-bearing metal (1.9 wt.% Si), Ti-bearing troilite, daubreelite, alabandite and schreibersite. The latter phases often occur as rounded enclaves in the enstatite. The meteorite is an unusual aubrite. It is similar in many respects to LEW 88055 (Casanova et al., 1993, LPSC XXIV, 259-260).
