green fluorite
Fluorite (also called fluorspar) is a halide mineral composed of calcium fluoride, CaF2.
Fluorite may occur as a vein deposit  where it often forms a part of the gangue
(the surrounding "host-rock" in which valuable minerals occur) and may be
associated with sphalerite, barite, quartz, and calcite.

Fluorite is a widely occurring mineral which is found in large deposits in many areas.
Notable deposits occur in Germany, Austria, Switzerland, England, Norway, Mexico,
and both Ontario and Newfoundland in Canada.  In the United States, deposits are
found in Missouri, Oklahoma, Illinois, Kentucky, Colorado, New Mexico, Arizona, Ohio,
New Hampshire, New York, Alaska and Texas.

Fluorite, or calcium fluoride (CaF2), is a simple halide commonly occurring as a glassy, hued, vein in a variety of mineral environments. It is commonly found in metallic hydrothermal deposits associated with lead, silver, galena, sphalerite, cobalt and other economic minerals. It also occurs in cavities of pegmatites,
in hot-springs areas and in sedimentary rocks, primarily limestones that
have been permeated by aqueous fluoride.
