PERMIAN BASIN PROVINCE (044) by Mahlon M
PERMIAN BASIN PROVINCE (044) By Mahlon M. Ball INTRODUCTION The Permian Basin is one of the largest structural basins in North America. It encompasses a surface area in excess of 86,000 sq mi and includes all or parts of 52 counties located in West Texas and southeast New Mexico. Structurally, the Permian Basin is bounded on the south by the Marathon-Ouachita Fold Belt, on the west by the Diablo Platform and Pedernal Uplift, on the north by the Matador Arch, and on the east by the Eastern Shelf of the Permian (Midland) Basin and west flank of the Bend Arch. The basin is about 260 mi by 300 mi in area and is separated into eastern and western halves by a north-south trending Central Basin Platform. In cross section, the basin is an asymmetrical feature; the western half contains a thicker and more structurally deformed sequence of sedimentary rock. The Permian Basin has been characterized as a large structural depression formed as a result of downwarp in the Precambrian basement surface located at the southern margin of the North American craton. The basin was filled with Paleozoic and, to a much lesser extent, younger sediments. It acquired its present structural form by Early Permian time. The overall basin is divisible into several distinct structural and tectonic elements. They are the Central Basin Platform and the Ozona Arch, which separate the Delaware and Val Verde Basins on the south and west from the Midland Basin on the north and east, the Northwestern Shelf on the southern extremity of the Pedernal Uplift and Matador Arch, and the Eastern Shelf on the western periphery of the Bend Arch. -

It has been partially updated to reflect more current events since its original production. Introduction The Marathon Overthrust (aka West Texas Overthrust/WTO) is a segment in far west Texas that runs from Canada, through the Appalachian and Ouachita Mountains of the United States, to Mexico. The complete thrust belt has been the site for oil and gas exploration for decades, for it has tectonically over-ridden a number of producing sedimentary basins. But until the last two decades, the complex geology of the thrusts obscured the hydrocarbon potential, and hampered development efforts. Recent discoveries in the Black Warrior Basin, the Arkoma Basin, the Ouachita Overthrust the Fort Worth Basin and the Marathon Overthrust have changed the way the industry views this trend. The WTO trend is characterized by stacked pay zones in multiple reservoirs and horizons. This trend, sourced by organically rich shale beds of Barnett and Woodford age with Total Organic Content/TOC ranging up to 13% is now considered one of the emerging pre-eminent resource plays in North America with larger conventional targets lying above and below it. -

F.; [eds.], New Mexico Geological Society 31st Annual Fall Field Conference Guidebook, 308 p. This is one of many related papers that were included in the 1980 NMGS Fall Field Conference Guidebook. Annual NMGS Fall Field Conference Guidebooks Every fall since 1950, the New Mexico Geological Society (NMGS) has held an annual Fall Field Conference that explores some region of New Mexico (or surrounding states). Always well attended, these conferences provide a guidebook to participants. Besides detailed road logs, the guidebooks contain many well written, edited, and peer-reviewed geoscience papers. These books have set the national standard for geologic guidebooks and are an essential geologic reference for anyone working in or around New Mexico. Free Downloads NMGS has decided to make peer-reviewed papers from our Fall Field Conference guidebooks available for free download. Non-members will have access to guidebook papers two years after publication. Members have access to all papers. This is in keeping with our mission of promoting interest, research, and cooperation regarding geology in New Mexico. However, guidebook sales represent a significant proportion of our operating budget. Therefore, only research papers are available for download. Road logs, mini-papers, maps, stratigraphic charts, and other selected content are available only in the printed guidebooks.

Gazetteer of Streams of Texas
DEPARTMENT OF THE INTERIOR FRANKLIN K. LANE, Secretary UNITED STATES GEOLOGICAL SURVEY GEORGE OTIS SMITH, Director Water-Supply Paper 448 GAZETTEER OF STREAMS OF TEXAS PREPARED UNDER THE DIRECTION OF GLENN A. GRAY WASHINGTON GOVERNMENT FEINTING OFFICE 1919 GAZETTEER OF STREAMS OF TEXAS. Prepared under the direction of GLENN A. GRAY. INTRODUCTION. The following pages contain a gazetteer of streams, lakes, and ponds as shown by the topographic maps of Texas which were pre pared by the United States Geological Survey and, in areas not covered by the topographic maps, by State of Texas county maps and the post-route map of Texas. For many streams a contour map of Texas, prepared in 1899 by Robert T. Hill, was consulted, as well as maps compiled by private surveys, engineering corporations, the State Board of Water Engineers, and the International Boundary Commission. An effort has been made to eliminate errors where practicable by personal reconnaissance. All the descriptions are based on the best available maps, and their accuracy therefore depends on that of the maps. Descriptions of streams in the central part of the State, adjacent to the Bio Grande above Brewster County, and in parts of Brewster, Terrell, Bowie, Casg, Btirleson, Brazos, Grimes, Washington, Harris, Bexar, Wichita, Wilbarger, Montague, Coke, and Graysoh counties were compiled by means of topographic maps and are of a good degree of accuracy. It should be understood, however, that all statements of elevation, length, and fall are roughly approximate. The Geological Survey topographic maps used are cited in the de scriptions of the streams and are listed below. -

Report 360 Aquifers of the Edwards Plateau Chapter 2
Chapter 2 Conceptual Model for the Edwards–Trinity (Plateau) Aquifer System, Texas Roberto Anaya1 Introduction The passage of Senate Bill 1 in 1997 established a renewed public interest in the State’s water resources not experienced since the drought of the 1950s. Senate Bill 1 of 1999 and Senate Bill 2 of 2001 provided state funding to initiate the development of groundwater availability models for all of the major and minor aquifers of Texas. The development and management of Groundwater Availability Models (GAMs) has been tasked to the Texas Water Development Board (TWDB) to provide reliable and timely information on the State’s groundwater resources. TWDB staff is currently developing a GAM for the Edwards–Trinity (Plateau) aquifer. An essential task in the design of a numerical groundwater flow model is the development of a conceptual model. The conceptual model is a generalized description of the aquifer system that defines boundaries, hydrogeologic parameters, and hydrologic stress variables. The conceptual model helps to compile and organize field data and to simplify the real-world aquifer flow system into a graphical or diagrammatical representation while retaining the complexity needed to adequately reproduce the system behavior (Anderson and Woessner, 1992). The first step in the development of a conceptual model is to delineate the study area and form an understanding of its physical landscape with regard to the physiography, climate, and geology. Another early step also involves the research and investigation of previous aquifer studies. Intermediate steps bring together all of the information for establishing the hydrogeologic setting which consists of the hydrostratigraphy, structural geometry, hydraulic properties, water levels and regional groundwater flow, recharge, interactions between surface water and groundwater, well discharge, and water quality.
