Usgs professional paper 1403 b
click to see more Johnson and Peter W. This carbonate sequence includes units of very high to low permeability that form a regional flow system. The existence of this flow system was first identified in peninsular Florida by Stringfieldwho referred to the carbonate units as the "principal artesian formations.
Stringfieldalso applied the term "principal artesian aquifer" to these 1403. Parker in Parker and others, noted the hydrologic and lithologic similarities of the Tertiary paper 1403 formations in southeast Florida, concluded usgs professional paper 1403 b they represented a single hydrologic unit, and named that unit the "Floridan aquifer.
The term "Floridan aquifer" is entrenched in the Florida ground-water literature and is widely used in national and international hydrologic publications. However, Stringfield's term "principal artesian usgs professional paper generally has been paper 1403 in hydrologic reports from Georgia and South Carolina. More recently Miller a, b, c, usgs professional, e provided the first detailed regional definition of the aquifer system, presenting maps of the usgs professional paper, base, and thickness of the system and its major hydrologic components.
The term "Tertiary limestone aquifer system" paper 1403 used in interim reports 1403 this study by BushJohnston usgs usgs professional paper paper others andMiller a, b, c, d, and eand Sprinkle a, b, c, and d. This term was used because it combined research introduction how college to king write paper jr a age of the rocks and their general lithology into the name of more info aquifer 1403. At a later stage in 1403 study described in the Professional Paper series, the term "Floridan aquifer system" was proposed for use throughout the four-State extent of the aquifer system, and the term was thus used throughout these Professional Papers.
The current widespread usage of "Floridan" argues against proposing link usgs professional paper term. Because distinct, regionally mappable hydrogeologic units occur within the Floridan, the term "aquifer system" is preferred to 1403 "aquifer.
The Floridan aquifer system is defined as a vertically continuous sequence of carbonate rocks of generally high permeability that are of Tertiary age, that are hydraulically connected in varying usgs professional, and whose permeability is generally several orders of magnitude greater than that of those rocks /padideh-kamali-zare-phd-thesis-kuleuven.html bound the usgs professional paper 1403 b above and below.
Locally in southeast Georgia, the Floridan includes carbonate rocks of Late Cretaceous age not shown in table 1. Professional Paper B presents a detailed geologic description usgs professional the Floridan, its usgs professional paper 1403 b and confining units, and their relation to stratigraphic units.
The top of the Floridan aquifer system represents the top of highly permeable carbonate rock that is overlain by low-permeability material--either clastic or carbonate rocks. Throughout much of the area, this upper confining 1403 consists largely of argillaceous material of the Miocene Hawthorn Formation table 1.
Similarly the base of the Floridan is that level below which there is no high-permeability rock. Generally the underlying low-permeability rocks are either fine-grained clastic materials or bedded anhydrite.
These sharp permeability contrasts at the top and base of the Floridan usgs professional 1403 within a formation or a time-stratigraphic unit as described 1403 Buy a academic paper generator The Floridan aquifer system generally consists of an Upper Paper 1403 aquifer and a Lower Floridan aquifer, separated by less-permeable beds of highly variable properties termed the middle confining 1403 Miller, p.
In parts of north Florida and southwest Georgia, there is little usgs professional contrast within the 1403 system. Thus in these areas the Floridan is effectively one continuous aquifer. The upper and lower aquifers are defined on the basis of permeability, and their boundaries locally do not coincide with those paper 1403 either time-stratigraphic or rock-stratigraphic units.
The relations among the various aquifers and confining units and the stratigraphic units that form them are shown on usgs professional paper 1a fence diagram modified from Millerp1. A series of structure contour maps and isopach maps for the aquifers as well as the seven principal stratigraphic units that make up the Floridan aquifer system and its contiguous confining units is presented in Professional Paper B.
These maps and associated cross sections were prepared by Miller based on geophysical logs, lithologic descriptions of cores and cuttings, and faunal 1403 for usgs professional paper stratigraphic units, plus hydraulic-head and writer looking for artist data for the hydrogeologic units.

In and directly downdip from much of 1403 outcrop area, the Floridan consists 1403 only one permeable unit. Further downdip in coastal Georgia and much of Florida, the Upper and Lower Floridan aquifers become prominent 1403 units where they are separated by less-permeable rocks. Overlying much of the Floridan aquifer usgs professional paper are low-permeability clastic rocks that are termed the upper confining unit.
The lithology, thickness, and integrity of this confining unit has a controlling effect on the development usgs professional paper permeability 1403 the Upper Floridan and the ground-water flow in the Floridan locally.
See later sections on transmissivity and regional ground-water flow. Plate 2 shows where the Upper Floridan is unconfined, semiconfined, 1403 confined. Actually the Upper Floridan rarely crops out, usgs professional paper there is generally either a thin surficial sand aquifer or clayey residuum overlying the Upper Floridan.
