# NASA data for MIL 05050 Weathering: B Fracturing: A/B Fa: 25-6 mol % Fs: 17-3 mol %
85% of this ordinary chondrites exterior has rough brown/black fusion crust with polygonal fractures. The interior is a black matrix with abundant chondrules of various sizes and colors.
The section exhibits numerous small, well-defined chondrules (up to 1.5 mm) in a black matrix of fine-grained silicates, metal and troilite. Silicates are unequilibrated; olivines range from Fa<sub class=xsmall>6-25</sub> and pyroxenes are Fs<sub class=xsmall>3-17</sub>. The meteorite is an L3 chondrite (estimated subtype 3.6).
