Evidence Of Variable Climate And Resources During The Late Pleistocene And Holocene At Gona, Ethiopia, Marie White Nov 2019

Evidence Of Variable Climate And Resources During The Late Pleistocene And Holocene At Gona, Ethiopia, Marie White

Steeplechase: An ORCA Student Journal

The African Humid Period (AHP) spanned a period of approximately 15 to 5 thousand years ago (ka) and resulted in Northern and Eastern Africa being wetter than today. This climate change event impacted flora, fauna, and humans to an unknown extent. Much of the work on the AHP across Eastern Africa utilizes lacustrine and marine proxies rather than river-based (fluvial). Gona, located in the Afar region of Ethiopia, is known for its extensive archaeological and fossil records in fluvial deposits. However, the paleoenvironment of the AHP at Gona has not been investigated. This study uses stratigraphy, geochronology, and paleopedology to …


Creation Of A Numerical Mathematical Model Of Geofiltration Processes And Its Adaptation For Solving Epignosic And Forecast Problems (In Terms Of Gurlen District Of Khorezm Region), Tolkun Mirakhmedov Sep 2018

Creation Of A Numerical Mathematical Model Of Geofiltration Processes And Its Adaptation For Solving Epignosic And Forecast Problems (In Terms Of Gurlen District Of Khorezm Region), Tolkun Mirakhmedov

Bulletin of National University of Uzbekistan: Mathematics and Natural Sciences

The article considers the creation of a mathematical model of geofiltration processes in Gurlen District. Methods for calculating and developing a mathematical model and algorithms were carried out, and applied software was developed, and the developed geofiltration mathematical model was adapted to solve the epignosic and forecast problems of the area under consideration.


Mineral And Fuel Resources Map Of Kentucky, Warren H. Anderson, Garland R. Dever Jr. Jan 2001

Mineral And Fuel Resources Map Of Kentucky, Warren H. Anderson, Garland R. Dever Jr.

Map and Chart--KGS

The production of minerals and fuels in Kentucky is a multibillion dollar industry. Historically, coal, oil, natural gas, limestone, sand and gravel, clay, fluorite, barite, lead, iron, phosphate, zinc, and brines have been produced in the state. These resources have greatly influenced the development of Kentucky by providing raw materials for the early settlers who settled the state and for current industrial and economic development. Electrical power for homes, businesses, and factories; materials for constructing houses, buildings, automobiles, and roads; and products we consume in everyday life come from the earth's mineral and fuel resources.

The ability to locate and …

Coal Resources Of The Lower Elkhorn Coal Bed In Eastern Kentucky, Ernest E. Thacker, Gerald A. Weisenfluh, William M. Andrews Jr., John K. Hiett Jan 2000

Coal Resources Of The Lower Elkhorn Coal Bed In Eastern Kentucky, Ernest E. Thacker, Gerald A. Weisenfluh, William M. Andrews Jr., John K. Hiett

Map and Chart--KGS

This chart is one of a series that shows the regional characteristics of the Lower Elkhorn coal. The maps were prepared as part of the U.S. Geological Survey's Natural Coal Assessment Program, which compiles regional maps and databases that provide a comprehensive assessment of the most important coal beds in the nation. The Lower Elkhorn coal is one of the leading producers in the state of Kentucky and has, in some areas, a reputation as an excellent metallurgical-grade coal. It is known locally as the Pond Creek, Imboden, Path Fork, Blue Gem, Straight Creek, Bruin or Vires coal bed. This …
