The Book of Genesis 2:7 states, "Then the Lord God formed man from the dust of the ground, and breathed into his nostrils the breath of life; and man became a living being" [15] [New Revised Standard Version translation]. In context, though, it is important to note that there are two creation stories in Genesis: the one just mentioned in 2:7 ...

Solid solution exists between dolomite, the iron-dominant ankerite and the manganese-dominant kutnohorite. [10] Small amounts of iron in the structure give the crystals a yellow to brown tint. Manganese substitutes in the structure also up to about three percent MnO. A high manganese content gives the crystals a rosy pink color.
Manganese is a silvery-gray metal that resembles iron. It is hard and very brittle, difficult to fuse, but easy to oxidize. [11] Manganese and its common ions are paramagnetic. [12] Manganese tarnishes slowly in air and oxidizes ("rusts") like iron in water containing dissolved oxygen. [13]
Mangalloy is made by alloying steel, containing 0.8 to 1.25% carbon, with 11 to 15% manganese. [1] Mangalloy is a unique non-magnetic steel with extreme anti-wear properties. The material is very resistant to abrasion and will achieve up to three times its surface hardness during conditions of impact , without any increase in brittleness which ...
Manganite is a mineral composed of manganese oxide-hydroxide, MnO(OH), crystallizing in the monoclinic system (pseudo-orthorhombic). [3] Crystals of manganite are prismatic and deeply striated parallel to their length; they are often grouped together in bundles. The color is dark steel-grey to iron-black, and the luster brilliant and ...
The advantage of combining powdered iron oxide and manganese oxide together is the lower melting point of the combined alloy compared to pure manganese oxide. [11] [12] In 1872, Lambert von Pantz produced ferromanganese in a blast furnace, with significantly higher manganese content than was previously possible (37% instead of the previous 12%).
Manganese(II,III) oxide is the chemical compound with formula Mn 3 O 4. Manganese is present in two oxidation states +2 and +3 and the formula is sometimes written as MnO · Mn 2 O 3 . Mn 3 O 4 is found in nature as the mineral hausmannite .
