Nashville Basin in Tennessee Nashville Basin fen. The Nashville Basin, also known as the Central Basin, is a term often used to describe the area surrounding Murfreesboro, Tennessee, in which Nashville is located. [1] The Central Basin was caused by an uplifting which produced a dome known as the Nashville Dome.
The basalt at Mole Hill (and other igneous dikes in the area) was originally thought to be of Paleozoic age by relative age dating using cross-cutting relationships. [1] In 1969, Fullagar and Bottino used K-Ar and Rb-Sr radiometric dating techniques to date rocks that they thought were temporally related to the Devonian Tioga Bentonite, but discovered that the rocks were actually a much ...
The Mississippi River as well as the Tennessee and Cumberland Rivers formed and cut deep into the valleys. The Nashville Basin, which in reality is a geologic dome, was pushed up from underneath by a mantle plume, exposing softer strata that with additional erosion on the Highland Rim surrounding the basin expanded the size of the basin. The ...
The Upper Tennessee Valley, looking east from the edge of the Cumberland Plateau near Rockwood, Tennessee. The Tennessee Valley begins in the upper head water portions of the Holston River, the Watauga River, and the Doe River in Northeast Tennessee and Southwest Virginia, as well as east of Asheville, North Carolina, with the headwaters of the French Broad and Pigeon rivers, all of which join ...
Kuwohi has two subpeaks: 6,560-foot (2,000 m) Mount Buckley to the west and 6,400-foot (1,950 m) Mount Love to the east. The headwaters of several substantial streams are located on the slopes of Kuwohi, including Little River on the north slope, and Forney Creek and Noland Creek, both of which are tributaries of the Tuckasegee River, on the south slope.
A 24-year-old Tennessee man has been arrested and charged with allegedly plotting to use a weapon of mass destruction in a neo-Nazi-inspired plot to destroy an energy facility near Nashville, the ...
The Mount Rogers area contains a unique record of the geohistory of Virginia. There is evidence from the rocks that volcanoes were part of the landscape. Roughly 760 million years ago, rift-related (divergent) volcanoes erupted along the axis of what later became the Appalachians, and one remnant of that volcanic zone, with its volcanic rocks, still can be seen at Mount Rogers.
