Peat depositional environments, the sites where and conditions under which peat
accumulates, significantly influence a resultant coal's physical properties, chemical …

This article addresses the fundamental difference between coal rank and coal type. While
theoretically settled long ago as being different aspects of coal systems science, the two …

Organic carbon burial plays a critical role in Earth systems, influencing atmospheric O2 and
CO2 concentrations and, thereby, climate. The Carboniferous Period of the Paleozoic is so …

To better understand the formation mechanism of coal-hosted Ge ore deposits, this paper
reports on the petrological, mineralogical, and geochemical compositions of the low-Ge …

A set of 11 Bolsovian coal seams from the German Ruhr Coal Basin were analyzed in
profiles for their organic geochemical and petrographic composition, aiming at the …

The high frequency of fires during the formation of some mire systems in the Jurassic is
thought to have influenced how terrestrial ecosystems evolved. Ancient mires, now present …

Large, globally documented negative δ 13 C excursions that occur across the Permian-
Triassic transition are thought to represent the isotopic fingerprint of considerable releases …

Today wildfire is an important disturbance in many continental ecosystems, and it is
assumed that with ongoing climate changes the frequencies and impacts of wildfires will …

This study presents recently collected data examining the organic petrology, palynology,
mineralogy and geochemistry of the Gray Hawk coal bed. From the Early Pennsylvanian …

At a symposium honoring the 50th anniversary of the University of Chicago, Gilbert Cady
introduced the concept of phyterals as a means of distinguishing the actual plant fossils from …
