Broader social forces were at work, as well. Blake believed that the automobile and television spelled the destruction of coal town baseball. The once vibrant Raleigh County League was gone by the mid1950s. John McGraw mined coal and played ball with his brothers Gene and Willard in Lillybrook. In the 1980s, after he retired, John McGraw was sad.
A coal ball is a type of concretion, varying in shape from an imperfect sphere to a flatlying, irregular slab. Coal balls were formed in Carboniferous Period swamps and mires, when peat was prevented from being turned into coal by the high amount of calcite surrounding the peat; the calcite caused it to be turned into stone instead.
During a visit to a chemical factory on 13 September, Xi underscored coal as China's "main [source of] energy". He ordered the coal industry to develop in a "green and lowcarbon" direction that would match the country's climate goals. In particular, Xi described the coaltochemical industry as having "great potential and promise".

They emerged from the mines, shook off the coal dust, and stepped onto the diamond. From the early 1900s to the 1950s, baseball games between mine workers were a smalltown phenomenon, each team attracting avid and intensely loyal fans. Talented parttime athletes competed at the amateur, semipro and professional levels. Equally competitive were the coal company officials, who often brought ...
Finally, other coalball deposits should be investigated for highMg calcite, and the relationship between the Ca/Mg ratio in coalball carbonates, epiric seas, and the open ocean of the Pennsylvanian should be explored. Coalball deposits, which span the Moscovian into the Kasimovian, could provide a new source of data for the Ca/Mg ratio of ...

Coal is a black or brownishblack sedimentary rock that can be burned for fuel and used to generate electricity. It is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion (burning). Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel ...
Goalball is a team sport that was specially designed for the visually impaired and blind and was invented in 1946 for veterans of the second world war who had lost their sight. Men's goalball made its Paralympic debut 30 years later, whereas women's goalball first appeared at the 1984 Games. Alternating between attacking and defending ...

These would ...
The inedible fungus Daldinia concentrica is known by several common names, including King Alfred's cake, cramp balls, and coal with other fungi the light spores are distributed globally and the fungi develop wherever conditions are suitable it lives on dead and decaying wood, and is a common, widespread saprotroph.. The fruit of this fungus is hemispherical, with a hard, friable ...
Identification and Description[iv] Daldinia concentrica is a relatively easy to identify mushroom that resembles hard, roundish lumps of coal stuck to the surface of decaying deadwood. Furthermore, unlike most other mushrooms, D. concentrica does not possess a cap, gills, pores, or even a stem. Instead, this species has a fruitbody composed of ...
coal ball, a lump of petrified plant matter, frequently spheroid, found in coal seams of the Upper Carboniferous Period (from 325,000,000 to 280,000,000 years ago). Coal balls are important sources of fossil information relating to the forests preceding the Coal Age. As a result of a variety of conditions, small pockets of plant debris in Carboniferous swamps, infiltrated by mineral salts ...

These "peels" are studied closely by scientists. It's a process that Tom Phillips created and others have developed. To date, U of I researchers throughout the decades have created more than 250,000 coal ball peels. Part of Lakeram's work is digitizing highmagnification images of them. "The point of digitizing the peels is (to ...
From the perspective of Phanerozoic time, coal balls are rare, apparently limited to a 24 interval (323299 Ma) in the Pennsylvanian and earliest within this interval, coal balls occur in many coals. Approximately 82 transgressiveregressive sedimentary cycles have been described for the Midcontinent, Illinois and Appalachian basins of North America during the midtolate ...

Coal Balls. Because coal balls are accumulations of (degrading) plant material (technically peat), they also are an excellent source of various forms of decaying organisms, including fungi. Numerous fungal remains have been found in coal balls, including hyphae, spores, and various types of reproductive structures.
Landscapes that would eventually fuel our industrial revolution thanks to the coal they produced, and that left us with both the most detailed and the richest paleobotanical record in the history of life on land in the form of coal balls: carbonate nodules that preserved plant tissues in the peat in cellular amounts of coal ball ...
