Adamite is a zinc arsenate hydroxide mineral, Zn 2 As O 4 OH. It is a mineral that typically occurs in the oxidized or weathered zone above zinc ore occurrences. Pure adamite is colorless, but usually it possess yellow color due to Fe compounds admixture. Tints of green also occur and are connected with copper substitutions in the mineral ...
In 1995, a single five foot long embolomere amphibian fossil was found in sandstone, near the margin of the Western Kentucky Coal Field. In the Pennsylvanian, shallow seas existed periodically, but the landscape was mostly swampy land. As the supercontinent Pangaea took shape, Kentucky was situated on the equator. Grasses and cordaite trees ...
They marked their territory on a single tree located in the mouth of the Kentucky River. [3] Daniel Boone and John Finley decided in 1769 to return to Kentucky to explore. Boone was the only person to survive the attacks of local Indian tribes, and remained in the wilderness of Kentucky until 1771.
Kentucky's Green River runs through a broad alluvial plain, from which outcroppings of bedrock project. The plain is an area that was inundated during the Pleistocene by a water body dubbed Lake Green, which resulted in the deposition of large amounts of silt. The middens of this district are typically located along the prehistoric routes of ...
Big Bone Lick State Park is located at Big Bone in Boone County, Kentucky. The name of the park comes from the Pleistocene megafauna fossils found there. [5] Mammoths are believed to have been drawn to this location by a salt lick deposited around the sulfur springs. [6]
The mine is known among mineral collectors for its arsenate minerals.Ojuela adamite and legrandite have set the standard for these species. The 117 species now known from the deposit include adamite (in an array of colors and habits), legrandite, köttigite/parasymplesite, and paradamite, as well as specimens of scorodite, hemimorphite, plattnerite, aurichalcite, rosasite, fluorite, calcite ...
The rubble would have traveled at up to about 2,200 miles (3,600 km) per hour, they found. One of the canyons, called Vallis Planck, measures about 174 miles (280 km) long and 2.2 miles (3.5 km) deep.
The Pottsville Escarpment is the transition zone from the central part of Kentucky to the higher and geologically younger Cumberland Plateau in the eastern part of the state. The Pennyroyal is bordered on the north by Muldraugh Hill , the geological escarpment that forms the transition from the geologically older Bluegrass to the Pennyroyal.
