These fine-grained achondrites vary in color from gray to tan to greenish and also contain various colored clasts. All possess varying amounts of fusion crust that is brown-black in color and usually contains small shiny patches. Most of them are “vuggy” and show varying degrees of weathering. Thin, black glassy veins are visible in the matrix. Some (usually the greenish ones) have areas of rusty-red minerals that have stained the adjacent minerals red.
