"I think that the most competent answer You will find here." PRZYLIBISKI T.A. et al. (2005) The Zaklodzie enstatite meteorite: Mineralogy, petrology, origin and classification (MAPS 40-9, pp. A185-A200, excerpt from p. A186): The Zaklodzie meteorite has a fusion crust 0.1-1.0 mm thick (average 0.3 mm); this crust is strongly weathered and contains iron oxides and hydroxides, evidence of prolonged terrestrial weathering. With the naked eye, three concentric zones varying in color can be distinguished in the stone. The outer zone A is the darkest, being dark grey with a rusty tint; the intermediate zone B is rusty-grey in color and the inner zone C is pale grey, locally nearly white. In the inner zone, opaque minerals make up ca. 10-15 vol% and are irregularly distributed. In the other two zones, opaques reach about 20 vol%. Within the relatively homogeneous texture of the meteorite, oval aggregates are locally present. They consist of several to tens of enstatite crystals and minor other minerals including metal and troilite. These forms were interpreted by some authors (Stepniewski et al. 2000; Manecki and Lodzinski 2001) as "relics of chondrules." About 4 inches of snow within two hours here!
