To develop a method for quantifying the vegetation of Pennsylvania-age coal beds, of four coal-ball (permineralized peat) profiles and four coal column samples from the Herrin coal bed (Kentucky No. 11) Carbondale Formation in western Kentucky were compared. An estimated 89.5% of the coal can be identified botanically.

Read MoreCoal deposits are scattered around the globe, but the coal from a 500 square mile region of northeastern Pennsylvania is special. During the Paleozoic era, 300 million years ago, what is now rugged and mountainous terrain was a steamy plain filled with swamps. Tropical plants grew and died here, and as decaying matter, sank to the bottom of ...

Read MoreIn northeastern Pennsylvania, however, the ordinary process of coal formation was accelerated by a violent upheaval known as the Appalachian Revolution. In this "revolution," rising mountains literally folded over, splitting open and thrusting up rock and peat formations from deep inside the earth.

Read MoreThe Lower Freeport coal bed in west-central Pennsylvania is interpreted to have formed within a lacustrine-mire environment. Conditions of peat formation, caused by the changing chemical and physical environments, produced five coal facies and two mineral-rich parting facies within the coal bed. The coal bed facies are compositionally unique, having developed under varying conditions, and are ...

Read MorePeat is the first step in the formation of coal, and slowly becomes lignite after pressure and temperature increase as sediment is piled on top of the partially decaying organic matter. In order to be turned into coal, the peat must be buried from 4-10 km deep by sediment. Since peat becomes coal over time, it is classified as a fossil product.

Read MoreHere people still cut peat blocks by hand, exposing layers of carbon-rich material, the precursor to coal. The peat is dried into lumpy bricks, to be burned for heat, a primitive fossil fuel. The land scars, and heals over, as it has done for thousands of years. Industrial peat extraction, however, is destructive and unsustainable.

Read MoreAs a result, wherever the peat was buried by marine sediments, the coal that eventually formed from it is high in sulfur. However, in a number of areas, nonmarine muds, silts, and sands from the river system on the coastal plain were deposited on the peat where flooding broke through natural levees or the river changed its course.

Read MoreCoal was also not collected in the interval just above the blue band. Both of these intervals contain coal balls. In plotting data from this column sample, a 10:1 compaction ratio for the coal-ball peat to coal was used; this was the nearest round number to the peat-to-coal compaction ratio obtained by Ryer and Lan- ger (1980).

Most people learn that coal is formed in swamps, but this is not completely accurate. The term "swamps" can be applied to many different types of wetlands, but coal only forms from peat-accumulating wetlands.
