Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

THE GROUNDMASS IS FINELY CRYSTALLINE BLUE OR PURPLE FLUORITE, THROUGH WHICH ARE SCATTERED SHORT LATHS AND WEATHERED MASSES OF LIGHT PINK BARITE AND CLUSTERS OF MEDIUM-GRAINED GREEN FLUORITE. NEAR THE MARGINS OF THE VEIN TINY CRYSTALS OF PYRITE AND LIMONITE PSEUDOMORPHS ARE COMMON. MINUTE CRYSTALS OF BASTNASITE OCCASIONALLY OCCUR.
