Colour ranges from pitch black to a gorgeous burntorange colour. Recently, very nice galena crystals have been found at Flamboro with wellformed crystals up to 25mm or so.
Dolomite is a very common mineral, and is known for its saddleshaped curved crystal aggregates.

Archaea of the ANME1 and ANME2 groups can coexist (Nauhaus et al., 2006). Nevertheless, archaea from the ANME2 group were found to have a preferential niche in habitats of elevated methane partial pressures (Blumenberg et al., 2004). The methane partial pressure is an important environmental factor, since it controls the mode of methane ...

Dolomite rhombs with cloudy centers and clear rims are also common in the Isla de Mona Dolomite. Cloudycentered dolomite rhombs are commonly found related to the limestonedolomite transition zone (Fig. 911E). Staining indicates that the center of the rhombs are calcitic. Dull luminescence is characteristic of this type of dolomite.

True Dolomite is sourced from rock and requires crushing and screening in order to be used in agriculture or industry. It is a carbonate limestone type product that should contain between 812% Magnesium as Mg and 1822% Calcium as Ca. Dolomite should contain less than % Sodium as well, so make sure you check this prior to purchasing.
The best dolomite is recovered from active quarries, but recent insurance and government regulations have caused the quarry operators to deny access to most people during the past year. Some north Arkansas clubs have managed to maintain good working relationships with certain operators and can still gain access for clubsponsored field trips.
