(1) Stalactite-like structures were common in the Black Sheep pocket, forming knobs and fingers of matrix covered with druzy quartz, fluorite , and galena crystals.
(2) Coexisting MI phases in these rocks include garnet, plagioclase, quartz, tourmaline and fluorite .
(3) A greisen is a quartz - mica aggregate containing significant amounts of cassiterite, wolframite, fluorite , topaz, rutile, and tourmaline.
(4) We looked at outcrops by the open pit and saw vugs everywhere with remnants of fluorite and barite crystals.
(5) Most specimens are on a typical brown goethite matrix and may have associated calcite, plattnerite, barite, fluorite , and hemimorphite.
