map of fault lines in kentucky

11) and continue mining. In eastern Kentucky, surface faults are relatively well mapped and relatively far . Harris (1970) has shown the fault to be a ramp on a bedding plane Within the thin Kentucky River valley along the northern edge of Madison County, and in the lower reaches of the valleys of the larger creeks that empty into the Kentucky River, most drilled wells will produce enough water for a domestic supply at depths of less than 100 feet. In 1996, the Education Committee of the Kentucky Geological Survey, in conjunction with the Kentucky Society of Professional Geologists, established the Earth Science Education Network (ESEN). The Kentucky Geological Survey states that there are four major fault lines that run through Kentucky: the New Madrid Fault Zone (NMFZ), Greenville Fault Zone (GFZ), Easterville Fault Zone (EFZ), and Cherokee Uplift (CU). GIS KT map from ArcGIS site: "1:24,000 Geologic Map Data for Kentucky in GeoSCiML. Webb (1969) and Silberman (1972) have interpreted subsurface data as regional facies relationships of the Lexington Limestone of central Kentucky and adjacent States as implying Kentucky and adjacent States, indicate that the dominant rock types east of the Grenville Front are granite The surface traces of faults are shown as black line segments on the geologic map, and offsets along some of the major faults are shown in the block diagram. The Moorman syncline extends into southern Illinois, where it is known as the Eagle These include (A) rotational faults (glide planes) bounding paleoslumps, (B) compactional faults along cutout (paleochannel) margins and around or beneath roof rolls, and (C) clay-vein faults. The debate over the maximum magnitudes of earthquakes is still ongoing and there has yet to be a definitive answer as the exact measurement of magnitude is hard to pin down due to the strength of the tectonic plates in different areas. Radon gas, although not widely distributed in Kentucky in amounts above the Environmental Protection Agency's maximum recommended limit of 4 picocuries per liter, can be a local problem. 0000001314 00000 n What states are on the Madrid fault line? section B-B' on sheet I of the geologic map). The 150-mile (240 km)-long seismic zone, which extends into five states, stretches southward from Cairo, Illinois; through Hayti, Caruthersville, and New Madrid in Missouri; through Blytheville into Marked Tree in Arkansas. This was followed by Middle(?) Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree. exposed and subjected to erosion only briefly at the end of the Ordovician, during the period of intensive In recent years, the risk of earthquakes in the C&E Tennessee seismic zone has increased due to the numerous chemical reactions, and the presence of active faults in the region. The last one was in 1884.
