Mississippian-Devonian Black Shales Of Kentucky: East-West Transect In Five Cores From The Appalachian Basin To The Illinois Basin, Patrick J. Gooding, Frank R. Ettensohn

Map and Chart--KGS

Devonian-Mississippian black shales are widespread across North America and underlie nearly 70 percent of Kentucky (Kepferle and Roen, 1981; Ettensohn and others, 1988). These black-shale units are among the most thoroughly investigated format ions in the commonwealth, because t hey have sourced most of t he conventional hydrocarbons (Gooding and Ettensohn, 2008; Gooding, 2013), have been major producers of gas in both the Illinois and Appalachian Basins, and have major potential as unconventional producers in both basins. In fact, maturation indicators such as vitrinite reflectance and total organic carbon, from both basins, show that the shales are most ly mature …

Kentucky Landscapes Through Geologic Time, Daniel I. Carey Jan 2011

Kentucky Landscapes Through Geologic Time, Daniel I. Carey

Map and Chart--KGS

We now understand that the earth’s crust is broken up into a number of plates, some of continental size, and that these plates have been moving— centimeters a year—throughout geologic history, driven by the internal heat of the earth. This movement creates our mountain chains, earthquakes, geologic faults, and volcanoes. The theory of plate tectonics (from the Greek, tektonikos: pertaining to building) attempts to describe the process and helps explain the geology of Kentucky.

The geologic story of the rocks that form Kentucky’s landscape began a half billion years ago when the area was covered by water. Deposits of sand, …

Kentucky Terrain, Daniel I. Carey, Terry D. Hounshell Jan 2008

Kentucky Terrain, Daniel I. Carey, Terry D. Hounshell

Map and Chart--KGS

The terrain of Kentucky has been shaped by geologic forces and the underlying rocks.Tectonic forces lifted, bent, and buckled the rocks–originally formed from sediments on shallow sea floors or swampy lowlands. Weathering and erosion shaved the hills and dissected the plains, exposing at the surface a cross section of rocks 250 to 500 million years old. The sands, gravels, silts, and clays of the Jackson Purchase Region are younger, remnants of a time when the sea lapped at the confluence of the Mississippi and Ohio Rivers.

The landforms in Kentucky are the result of the differential weathering of interbedded sandstones, …

Generalized Geologic Map For Land-Use Planning: Green County, Kentucky, Daniel I. Carey, Adam Pike

Map and Chart--KGS

This map is not intended to be used for selecting individual sites. Its purpose is to inform land-use planners, government officials, and the public in a general way about geologic bedrock conditions that affect the selection of sites for various purposes. The properties of thick soils may supercede those of the underlying bedrock and should be considered on a site-to-site basis. At any site, it is important to understand the characteristics of both the soils and the underlying rock.
