Various factors can lead to the transformation of metal forms and to an increase in their solubility and, consequently, their mobility. One solution to the problem of increased solubility is the use of carbons as additives to soil in order to limit the potential migration of contaminants. The aim of this study was to determine the effect of using brown coal and activated carbon on metal forms ...

Coal Plant Matter, Carbonization, Sedimentary Rocks: It is generally accepted that most coals formed from plants that grew in and adjacent to swamps in warm, humid regions. Material derived from these plants accumulated in lowlying areas that remained wet most of the time and was converted to peat through the activity of microorganisms.

Therefore, geologists have long assumed that coal is a form of peat created by the heat and pressure of deep burial. The geologic process of turning peat into coal is called "coalification." Coal beds are much, much larger than peat bogs, some of the tens of meters in thickness, and they occur all over the world.
