Ore deposits The manganese ore is a stratiform type occupying more or less the same stratigraphic horizon in the dolomitic limestone member of the Um Bogma formation which caps the clastic Adedia formation. Ore deposits always tend to occupy a particular stratigraphic horizon (i.e. Dolomite and manganese-bearing member), representing the base ...

Dolomite is a common rock-forming mineral. It is a calcium magnesium carbonate with a chemical composition of CaMg (CO 3) 2. It is the primary component of the sedimentary rock known as dolostone and the metamorphic rock known as dolomitic marble. Limestone that contains some dolomite is known as dolomitic limestone.
