Macerals, Coal, Kentucky Geological Survey, University

2019-9-19  Macerals are the altered remains and byproducts of the original plant material from which the coal-forming peat originated. Macerals are to coal as sediment grains and cements are to sedimentary rocks. Coal petrographers (people who study coal under a microscope) separate macerals into three groups, each of which includes several maceral types.

Geologic framework for the coal-bearing rocks of the

Coal production has been an important economic factor in the Central Appalachian Basin. However, regional stratigraphic and structural relationships of the coal-bearing rocks of the basin have been poorly understood due to numerous separate nomenclatural schemes employed by various states. In order to estimate coal resources and understand mechanisms controlling the distribution of coal within

Rocks and Minerals: Aplite, Coal, Quartz, Feldspar

2021-1-5  Rocks and Minerals: Aplite, Coal, Quartz, Feldspar Essay. Aplite is an intrusive rock containing the quartz and feldspar mineral; aplite rocks have a grey, whitish, or pinkish color, and they are excellent (Welch, 2011). Additionally, aplite crystals are quite defective and solidify almost immediately, but they fit closely similar to the mosaic

Basics--Rocks and Minerals

2021-6-12  Coal is the most abundant fossil fuel on Earth. Its predominant use has always been for producing heat energy. It was the basic energy source that fueled the Industrial Revolution of the 18th and 19th centuries, and the industrial growth of that era in turn supported the large-scale exploitation of coal deposits. Since the mid-20th century, coal

"Mechanical Properties of Coal Measure Rocks

The sedimentary rock that comprises coal measures has quite nonlinear, elastic, stress strain characteristics. It is also affected by the fluid pressure within it. The fluids act in two quite separate ways. The first way in which fluid acts is in a poroelastic manner while the second is within fractures. These effects are important in rock behaviour, extending from the deformation around a
