 · The manganese minerals constitute about 70 % of the rock while calcite and quartz are the secondary minerals. Manganese occurs as anhedral rounded to sub rounded grains where most of the grains vary from 0.02mm to 0.3 mm in size. The margins of the grains are curved in most of the cases where the grains are distinguished from one another.

Although manganese forms a part of over one hundred minerals, and is a relatively widespread element, practically all the manganese in the United States occurring in nature in sufficient quantity to be of commercial value comes from the oxides, mainly psilomelane and pyrolusite. Other oxides are mined, but much less frequently.

 · Manganese is an essential mineral. It is needed by the body in very small amounts. It is important in building bone, healing wounds, and in how the body uses carbohydrates and amino acids. Manganese is concentrated in the mitochondria of cells. Most of it is found in the bone, liver, pancreas, and kidney cells.

 · The mixing parameters for the Mn-bearing minerals were estimated using the micro-ϕ approach of Powell et al. (2014, Journal of Metamorphic Geology, 32, 245–260). Then the Mn-end-member thermodynamic properties were calibrated using a database of co-existing minerals involving literature data from rocks and from experiments on natural materials.
