Mechanical and thermal control of cleating and shearing in coal: examples from the Alabama coalbed methane field, USA Mechanical and thermal control of cleating and shearing in coal: examples from the Alabama coalbed methane field, USA

Natural fractures provide most of the interconnected macroporosity in coal. Therefore, understanding the characteristics of these fractures and the associated mechanisms of formation is essential for effective coalbed methane exploration and field management. Natural fractures in coal can be divided into two general types: cleat and shear structures. Cleat has been studied for more than...

200,000 years of climate change recorded in eolian sediments of the High Plains of eastern Colorado and western Nebraska 200,000 years of climate change recorded in eolian sediments of the High Plains of eastern Colorado and western Nebraska

Loess and eolian sand cover vast areas of the western Great Plains of Nebraska, Kansas and Colorado (Fig. 1). In recent studies of Quaternary climate change, there has been a renewed interest in loess and eolian sand. Much of the attention now given to loess stems from new studies of long loess sequences that contain detailed records of Quaternary glacial-interglacial cycles, thought to...
