A few dozen dull, dark brown Limonite crystals coat the siliceous base of this hand specimen. They are in very good condition, showing little damage, and reach lenghts of nearly 0.4" (1 cm). As the crystals pseudomorphed from marcasite, they have retained the orthorhombic form and "coxcomb" habit of that mineral- most of the "coxcombs" are ...
