What Is a Salt Dome? How Do They Form? 3/2/18, 4:06 PM What Is a Salt Dome?
What is a Salt Dome? How do they form? 3/2/18, 4:06 PM What is a Salt Dome? » » Salt Domes Columns of salt that intrude through overlying sediment units. Middle Jurassic salt: This cross-section shows rocks of the East Texas Basin between the Oklahoma-Texas border (on the left) and the Gulf of Mexico coastline (on the right). The purple rock unit is the Middle Jurassic salt, a rock unit that has the ability to flow under pressure. The salt is overlain by thousands of feet of sediment which place enormous pressure on the surface of the salt and cause it to flow. At numerous locations the salt has intruded upwards into overlying sediments. This has produced small mounds or towering columns of salt that can be thousands of feet tall. The salt columns and smaller mounds are called "salt domes." USGS image [1]. https://geology.com/stories/13/salt-domes/ Page 1 of 12 What is a Salt Dome? How do they form? 3/2/18, 4:06 PM Salt Dome: Cartoon of a salt dome showing piercement through two rock units and deformation of the rock unit immediately above. Growth of the dome is accomplished by migration of salt into the dome from surrounding areas. The salt migrates into the dome because it is compressed by the weight of overlying sediments. What is a Salt Dome? A salt dome is a mound or column of salt that has intruded upwards into overlying sediments. Salt domes can form in a sedimentary basin where a thick layer of salt is overlain by younger sediments of significant thickness. -

ABSTRACT Magnetic Investigation of the Continental-Oceanic Crustal
ABSTRACT Magnetic Investigation of the Continental-Oceanic Crustal Boundary; Northern Gulf of Mexico Mark Speckien, M.S. Mentor: John A. Dunbar, Ph.D. Current mapping of magnetic intensity data shows that the Gulf Coast magnetic anomaly is not one anomaly but two distinct anomalies, with one portion trending parallel to the margin before curving northward through central Texas, and then northeastward into the Balcones Fault Zone along the eastern trace of the Ouachita Deformation Front, and the other following the coastline into Louisiana. Multiple profiles perpendicular to the geologic strike of the anomalies lead to the interpretation of these anomalies as the superposition of a normal rifting feature and a pre-existing crustal feature remnant of a complex tectonic history in the region. The location of the pre-existing feature and the rift anomaly suggest pre-rifting lithosphere conditions influenced the rifting process as seen in other passive rifting models.

SUBMITTED ABSTRACTS The Mesozoic of the Gulf Rim and Beyond: New Progress in Science and Exploration of the Gulf of Mexico Basin 2016 GCSSEPM Conference, December 8-9, 2016, Houston, Texas Deep-seated dynamics including crust and upper mantle impacting hydrocarbon localization within sediment-filled basins Rich Adams and Allen Lowrie Hydrocarbons occur within sediments in basins within the uppermost crust. Localization is affected by regional temperature and pressure gradients as well as anomalies in sediment distribution; porosity and permeability; and breakages (faults, joints and fractures) in both soft and hard materials. In our search for these hydrocarbons, we map and record geophysical and geochemical anomalies, generally caused by sediment and crustal tectonics. Many of these in turn appear influenced and guided by lower crust-upper mantle interactions that include, among others, buoyant mantle plumes and lateral plate tectonics. In order to better understand how such a total geologic system operates, it is necessary to think of this entire sediment - basin - crust - upper mantle complex as a single unit. We must seek new and pertinent explanations for hydrocarbon occurrences including these mantle and crust influences as we extend our exploration models into new frontiers. In summary, the cumulative actions of the entire geologic system including upper mantle to upper crust create forces and dynamics capable of modifying overlying basins and hydrocarbon- bearing sediments recording these underlying forces. We suggest that the whole petroleum system concept needs examination in light of upper mantle and crust dynamics. With mantle plumes causing the Late Triassic North Atlantic Rifting, the evolutionary scenario here is appropriate explanation for continental rifting followed by basin initiation and subsequent deepening and in-filling and locating hydrocarbons. -

Petroleum Source Rocks of the Onshore Interior Salt Basins, North
Petroleum Source Rocks of the Onshore Interior Salt Basins, North Central and Northeastern Gulf of Mexico Ernest A. Mancini1, Peng Li1; Donald A. Goddard2; Ronald K. Zimmerman3 1 Center for Sedimentary Basin Studies and Department of Geological Sciences, University of Alabama, Box 870338, Tuscaloosa, AL 35487-0338 2 Center for Energy Studies, Louisiana State University, Baton Rouge, LA 70803 3 Louisiana Geological Survey, Louisiana State University, Baton Rouge, LA 70803 Abstract Understanding the burial and thermal maturation histories of the strata in the onshore interior salt basins of the north central and northeastern Gulf of Mexico area is critical in petroleum source rock identification and characterization. The burial and thermal maturation histories of the strata in these basins and subbasins are consistent with the rift-related geohistory of these features. Source rock analysis and thermal maturity modeling indicate that lime mudstone of the Upper Jurassic Smackover Formation served as an effective regional petroleum source rock in the North Louisiana Salt Basin, Mississippi Interior Salt Basin, Manila Subbasin and Conecuh Subbasin. The Upper Cretaceous marine shale was an effective local petroleum source rock in the Mississippi Interior Salt Basin and a possible local source bed in the North Louisiana Salt Basin given the proper organic facies. Lower Cretaceous lime mudstone was an effective local petroleum source rock in the South Florida Basin, and these rocks were possible local source beds in the North Louisiana Salt Basin and Mississippi Interior Salt Basin given the proper organic facies. Uppermost Jurassic strata were effective source rocks in Mexico, and therefore, were possible source beds in the North Louisiana Salt Basin given the proper organic facies. -

Chapter 2 Geology of the Gulf Coast Aquifer, Texas Ali H. Chowdhury, Ph.D., P.G.1 and Mike J. Turco2 Introduction The Gulf Coast aquifer in Texas extends over 430 miles from the Texas-Louisiana border in the northeast to the Texas-Mexico border in the south (Figure 2-1). Over 1.1 million acre-feet of groundwater are annually pumped from this aquifer in Texas. A large portion of this water supply is used for irrigation and drinking water purposes by the fast growing communities along the Texas Gulf Coast. The geology of the Gulf Coast aquifer in Texas is complex due to cyclic deposition of sedimentary facies. Sediments of the Gulf Coast aquifer were mainly deposited in the coastal plains of the Gulf of Mexico Basin. These sediments were deposited under a fluvial-deltaic to shallow-marine environments during the Miocene to the Pleistocene periods. Repeated sea-level changes and natural basin subsidence produced discontinuous beds of sand, silt, clay, and gravel. Six major sediment dispersal systems that sourced large deltas distributed sediments from erosion of the Laramide Uplift along the Central and southern Rockies and Sierra Madre Oriental (Galloway and others, 2000; Galloway, 2005). Geographic locations of the various fluvial systems remained relatively persistent, but the locations of the depocenters where the thickest sediment accumulations occurred shifted at different times (Solis, 1981). Stratigraphic classification of the Gulf Coast aquifer in Texas is complex and controversial, with more than seven classifications proposed. However, Baker’s (1979) classification based on fauna, electric logs, facies associations, and hydraulic properties of the sediments has received widespread acceptance. -

Geological Survey, 604 South Pickett Street, Alexandria, VA 22304 ASSESSMENT OF RECOVERABLE ENERGY RESOURCES The World Energy Resources Program of the U.S. Geological Survey (USGS) intends to develop reliable and credible estimates of undiscovered recoverable petroleum resources throughout the world. Initial program efforts have focused on the major producing areas of the world to gain a broad geological understanding of the characteristics of petroleum occurrence for purposes of resource assessment, as well as for analysis of production potential. Investigations of production potential are carried out in cooperation with other U.S. Government agencies; specifically, the studies of the main free world exporting nations, of which this study is a part, are carried out in cooperation with the Foreign Energy Supply Assessment Program of the Department of Energy.
