Model Ordinance For Development On Karst In Kentucky: Guidance For Construction On Karst Terrain And The Reduction Of Property Damage And Threat To Human Health Resulting From Karst Geologic Hazard, James C. Currens
Information Circular--KGS
I have dealt with hundreds of incidents of karst-related geohazards; some have caused major damage to buildings and infrastructure. Although cases are largely limited to the ground surface being made unusable, a significant number of structures are damaged by karst flooding or cover collapse each year, which is devastating to families who have lost their homes. Most of these events should never have happened, because the karst hazard could have been avoided by selecting a better building site or designing the building to withstand the damage from the hazard. Furthermore, most of the planning authorities I have had experience with …
Depositional Environments And Sequence Stratigraphy Of A Breathitt Group Exposure, U.S. 25e, Flat Lick, Kentucky, Kathryn E. Hoffmeister, Eric G. Hogan, Steven M. Holland
Depositional Environments And Sequence Stratigraphy Of A Breathitt Group Exposure, U.S. 25e, Flat Lick, Kentucky, Kathryn E. Hoffmeister, Eric G. Hogan, Steven M. Holland
Information Circular--KGS
The Pennsylvanian fluvial deltaic Breathitt Group is exposed along U.S. 25E near Flat Lick, Ky. This exposure is ideal for field trips because of the quality of the exposure, its accessibility, the range of facies present, and its potential for demonstrating principles of outcrop-based sequence-stratigraphic interpretation. Eight facies are present and represent deposition in fluvial, delta-plain, and delta-front environments. Several facies contain an abundance of trace fossils, and a wide range of sedimentary structures are also present. Flooding surfaces are well developed in the delta front and delta plain and are characterized by abrupt contacts with distal, deeper-water deltaic environments …
