Extent

The Richmond Basin is a rift basin, making a north to south double pointed oval, with the eastern edge over the Swift Creek Reservoir, with the northern point at interstate 64, spanning the James River, with the southern point at the Appomattox River.

Richmond Basin geology

The Richmond Basin is 205 to 245 million years old. Pangea divided and many small rifts split opened in the earth in addition to the large one that became the Atlantic Ocean. When Richmond rift opened and filled with swamps from water in the Pamunkey River, sediment filled in over the swamps and the sedimentary pressure converted organic plant material into coal. This weight is less pressure than coal deposits produced when the continents were pushing together and raising up mountains. Semi-anthracite and anthracite are often formed by such tectonic squeezing when continents push together. The Richmond Basin has Bituminous coal, formed by the sedimentary weight only. [1]

The coal deposits were on a thin shale and sandstone layer over the granite bedrock. Oolite or small round grains of calcium carbonate was over the coal. Some coke with and without sulphur was with the coal. [2]

To the northwest of the basin is the Goochland Terrane, and between them is the Boscobel complex. [3]

Richmond Basin mining

The Richmond Basin is located near Midlothian, Virginia, in Chesterfield County, Virginia. It was mined in the early 18th century. Coal was carried on the Chesterfield Railroad in gravity and mule-pulled carts to Manchester, Richmond, Virginia and Richmond, Virginia. Wood burning trains, such as the Clover Hill Railroad then the Brighthope Railway transported the coal found at Clover Hill in later years. The coal from Midlothian, Virginia was mainly used in Richmond, Virginia and Petersburg, Virginia. The Clover Hill Pits in Winterpock, Virginia were sold as far away as New York City from the 1840s to the 1890s. [4] [5] The supply was not as great and as cheap to mine as the Pocahontas coalfield, however and mining the Richmond Basin was ended around 1890. Richmond and Petersburg grew economically because of manufacturing supported by the James River and Appomattox River waterpower, more than from coal brought out of Midlothian and Clover Hill." [1]

<span class="mw-page-title-main">Geology of Massachusetts</span>

The geology of Massachusetts includes numerous units of volcanic, intrusive igneous, metamorphic and sedimentary rocks formed within the last 1.2 billion years. The oldest formations are gneiss rocks in the Berkshires, which were metamorphosed from older rocks during the Proterozoic Grenville orogeny as the proto-North American continent Laurentia collided against proto-South America. Throughout the Paleozoic, overlapping the rapid diversification of multi-cellular life, a series of six island arcs collided with the Laurentian continental margin. Also termed continental terranes, these sections of continental rock typically formed offshore or onshore of the proto-African continent Gondwana and in many cases had experienced volcanic events and faulting before joining the Laurentian continent. These sequential collisions metamorphosed new rocks from sediments, created uplands and faults and resulted in widespread volcanic activity. Simultaneously, the collisions raised the Appalachian Mountains to the height of the current day Himalayas.

<span class="mw-page-title-main">Brighthope Railway</span>

In 1886, Randolph Harrison, of the Virginia department of Agriculture, cited Cumberland Mining Company, stating that the United States had purchased stock in the Brighthope Railway. He continued by citing their assertion that extending the railway into Cumberland would increase the value of farms there because they could sell consumer agricultural products such as fruit, dairy and vegetables to all markets of Virginia. The Brighthope Railway was founded in 1877 by the creditors of the Clover Hill Railroad who bought that railroad when the Clover Hill Railroad went bankrupt. The Brighthope Railway continued in the role of the Clover Hill Railroad, hauling coal from the Clover Hill Pits at Winterpock, Virginia. In addition to coal, the Bright Hope Railway transported timber and agricultural products and had passenger service. The Bright Hope Railway was narrowed from standard gauge to narrow gauge and rerouted in 1881. In 1886, much of the southern rails were changed to standard gauge. The Brighthope Railway was not changed back.

<span class="mw-page-title-main">Clover Hill Railroad</span>

The Clover Hill Railroad was a railroad company that operated for 36 years in central Virginia near Richmond. The railroad was created to carry coal most efficiently from the Clover Hill Pits in Winterpock, Virginia, to further transportation points in Chester, Virginia, where it could be sold for a better price than on the Appomattox River in the Piedmont region. This made the railroad important to the Confederacy in the Civil War to ensure a supply of coal for munitions and iron working. The mines were dangerous for the miners, and many accidents occurred. The railroad had to be sold when coal mining declined so that new owners could find other uses for the railroad.

The Clover Hill Pits are a number of coal shafts and mines that operated in the Southside area of Richmond, Virginia from 1837 until around 1883.

The Farmville and Powhatan Railroad went bankrupt in 1905 and became the Tidewater and Western Railroad. The line survived until 1917 when it was pulled up and sent to France for the World War I effort. The Tidewater and Western Railroad carried freight and passengers along a route from Farmville, Virginia to Bermuda Hundred. The Tidewater and Western Railroad continued to have Western Union Telegraphs run along the rails. These connected to telegraphs on the Atlantic Coast Line along the East Coast of the US and to Europe.

<span class="mw-page-title-main">Upper Appomattox canal system</span>

The Upper Appomattox Canal Navigation system allowed farmers who took their wheat and corn to mills on the Appomattox River, as far way as Farmville, Virginia, to ship the flour all the way to Petersburg from 1745 to 1891. The system included a navigation, modifications on the Appomattox River, a Canal around the falls Petersburg, and a turning basin in Petersburg to turn their narrow long boats around, unload the farm products from upstream and load up with manufactured goods from Petersburg. In Petersburg, workers could put goods on ships bound for the Chesapeake Bay and load goods from far away for Farmville and plantations upstream. Canal boats would return up river with manufactured goods. People who could afford it, rode in boats on the canal as the fastest and most comfortable ride. The river was used for transportation and shipping goods for over 100 years.

The geology of Virginia began to form 1.8 billion years ago and potentially even earlier. The oldest rocks in the state were metamorphosed during the Grenville orogeny, a mountain building event beginning 1.2 billion years ago in the Proterozoic, which obscured older rocks. Throughout the Proterozoic and Paleozoic, Virginia experienced igneous intrusions, carbonate and sandstone deposition, and a series of other mountain building events which defined the terrain of the inland parts of the state. The closing of the Iapetus Ocean, to form the supercontinent Pangaea added additional small landmasses, some of which are now hidden beneath thick Atlantic Coastal Plain sediments. The region subsequently experienced the rifting open of the Atlantic Ocean in the Mesozoic, the development of the Coastal Plain, isolated volcanism and a series of marine transgressions that flooded much of the area. Virginia has extensive coal, deposits of oil and natural gas, as well as deposits of other minerals and metals, including vermiculite, kyanite and uranium.
