Abstract

Spotlight on Geochemical Studies Outcomes for Mn Ore Deposits of Um Bogma, West-Central Sinai, Egypt

Metwally Hamza*

Manganese ore is essential in industry, mining, laboratory experiments, and for whole life in general, that’s only because it’s widely used as sulfur-fixing, deoxidizing, and alloying metallic material. In this regard, Mn has medically considered a trace element that is present in a relatively small amount in the human body, an average of 20 mg.

Manganese is the 12^th most abundant element in the Earth's crust, which occupies about 1000 ppm of it, with a percentage of 0.1%. All soils in general contain about 440 ppm of such an element. In addition, the atmosphere’s manganese ratio is 0.01 μg/m³.

The geology and mineralogy of the Mn deposits of the Um Bogma Region, in west-central Sinai, had been previously studied by some investigators. There is a dispute between investigators about the origin of the most economic Mn ore deposits in Egypt, located in the Um Bogma Region.

Many investigators had put the evidence for the Mn deposits to be epigenetic in origin and maintained that these deposits had been deposited as a result of the activity of mineralized hydrothermal fluids. Other investigators maintained that these Mn ore deposits are considered primary sedimentary-type in origin.

In the present paper, the geochemical studies of the manganese deposits of Um Bogma Region, West-central Sinai, Egypt, done by some investigators will be surveyed and discussed, on the way to determine the origin of such deposits. The present paper is mainly based on the graduation project thesis of the paper’s author.
