# NASA data for DEW 96601 Weathering: B/Ce Fracturing: A/B Fa: 14-21 mol % Fs: 17-3 mol %
The exterior has brown/black fusion crust with oxidation halos and some evaporites. The interior has a sugary texture with rusty metal grains. Dark and light colored chondrules are visible and some rusty inclusions are present.
The section exhibits numerous small, well-defined chondrules (up to 1 mm) in a black matrix of fine-grained silicates, metal and troilite. Weak shock effects are present. Polysynthetically twinned pyroxene is extremely abundant. Weathering is pervasive. Silicates are unequilibrated; olivines range from Fa₁₄₋₂₁ and pyroxenes from Fs₃₋₁₇. The meteorite is probably an H3 chondrite (estimated subtype 3.8).
