Subsidence hazards due to evaporite dissolution in the United States
Kenneth S. Johnson
2005, Environmental Geology (48) 395-409
Evaporites, including gypsum (or anhydrite) and salt, are the most soluble of common rocks; they are dissolved readily to form the same type of karst features that typically are found in limestones and dolomites, and their dissolution can locally result in major subsidence structures. The four basic requirements for evaporite...

Palynology in coal systems analysis-The key to floras, climate, and stratigraphy of coal-forming environments
D. J. Nichols
2005, Special Paper of the Geological Society of America 51-58
Palynology can be effectively used in coal systems analysis to understand the nature of ancient coal-forming peat mires. Pollen and spores preserved in coal effectively reveal the floristic composition of mires, which differed substantially through geologic time, and contribute to determination of depositional environment and paleo- climate. Such applications are...
