Description
Comments:Much of the dolomite is of a fetid variety. Much of it is also triboluminescent and thermoluminescent. Occasionally it is phosphorescent. The writer has found no fluorescent dolomite to date.
In addition to the crystalline variety, there occurs also a white sugary dolomite which is quite common throughout the area.
Light to dark masses and seams of massive cleavable dolomite occur throughout the deposit. Some of it may be found in intimate contact with the tremolite. Much of this cleavage material is fetid. It occasionally contains vugs wherein one may find rhombohedral crystals of dolomite.
Rhombic crystals of dolomite both clear and of varying shades of gray are found. None found by the writer has been curved. No pink dolomite or crystals have been found. The pink-colored dolomite, which has been reported, is a hematite or limonite stained dolomite from the alteration of pyrite, chalcopyrite and pyrrhotite.
Occasional masses of dark to almost black dolomite occur. These are usually low in magnesium with mud or other impurities furnishing the darkening quality.
Habit:mostly massive, rhombohedral where crystallized
Colour:gray to black
