Vitamins and Minerals The Nutrition Source
Vitamins and minerals are micronutrients required by the body to carry out a range of normal functions. However, these micronutrients are not produced in our bodies and must be derived from the food we eat. Vitamins are Iron in diet. Iron is a mineral found in every cell of the body.

1. Introduction. Peatlands are wetlands with organic matter content exceeding 30% and peat thickness of at least 30 cm (Chai, 1990, Gorham, 1991, Page and Baird, 2016).Peatlands store approximately one third of soil carbon globally despite covering only 3% of the land surface (Gorham, 1991, Yu et al., 2010), which is equivalent to more Iron is critically important and highly regulated trace metal in the human body. However, in its free ion form, it is known to be cytotoxic; therefore, it is bound to iron storing protein, ferritin. Ferritin is a key regulator of body iron homeostasis able to form various types of minerals depending on the tissue environment.

Ironstones and iron formations SpringerLink
The main iron minerals fall into four groups which James (1954) used to define four “facies” of iron formation: oxide, silicate, carbonate, and sulfide. In low-grade iron formations, the dominant minerals are magnetite and hematite in the oxide facies; greenalite and minnesotaite in the silicate facies; siderite and ankerite in the carbonate facies; and pyrite Vitamin B 12.

By 2500 BC, an iron industry existed in central India and by 1500 BC sites have large heaps of cinders and slag. Hittites developed iron for weaponry by 1400 BC as well (Souckova-Sigelová 2001; Killick 2014) which also attested by Egyptian accounts of the in 1274 BC. Cast iron metallurgy was developed in the Far East as well as Southwest Asia.Oxidation of iron-rich rock is known to generate H2 in oceanic as well as in continental domains.

Until recently, the classic approach to mineral exploration studies was to bring the field samples/drill cores collected during field studies to the laboratory, followed by laborious analysis procedures to generate the analytical data. This is very expensive, time-consuming, and difficult for exploring vast areas. However, rapid technological advances Detailed mineralogical information from underground coal gasification (UCG) is essential to better understand the chemical reactions far below the surface.
