Groundwater In The Inner Bluegrass Karst Region, Kentucky, John Thrailkill, Lawrence E. Spangler, William M. Hopper Jr., Michael R. Mccann, Joseph W. Troester, Douglas R. Gouzie

KWRRI Research Reports

The hydrogeology of about 12% of the 5600 km² Inner Bluegrass Karst Region of central Kentucky was investigated by water tracing and other techniques. Using fluorescent dyes adsorbed on fabric and charcoal detectors, 96 traces (average length 2.7 km, maximum length 15 km) resulted in the identification of 38 groundwater basins (with areas up to 15 km²). Within the basins, subsurface flow is in a dendritic conduit system at depths up to 30 m below the surface, while in the interbasin areas which separate them flow is generally less than 5 m deep. Each groundwater basin discharges …

Petrology Of The Middle Cambrian Blacksmith Formation, North-Central Utah, Howard William Hay Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The dolostones and dolomitic limestones of the Middle Cambrian Blacksmith Formation were studied in the Bear River and Malad Ranges and the Wellsville Mountains of north-central Utah. The depositional textures and sedimentary structures retained within the rocks form the basis of subdivisions of measured sections, interpretation of depositional paleogeography, and reconstruction of environments.

Other studies of modern carbonate environments and their ancient analogues provided the basis for interpretation of the depositional textures found within the rocks of the Blacksmith Formation. Four identifiable lithofacies were recognized within the study area. These facies include: (1) oolite shoal; (2) restricted lagoon; (3) low- …
