Non-traditional sources of critical minerals from the Western Canada Sedimentary Basin
… non-traditional sources of the Western Canada Sedimentary Basin (WCSB) with a focus on REE from coal combustion by-products (CCBs) and Li from basinal brines. The first phase of this work used machine learning to identify geochemical indicators of REE enrichment in sedimentary strata which can …

Effects of erosion on pore pressure and groundwater flow in the Western Canada Sedimentary Basin
… sediments over much of the western Canada sedimentary basin. I used a numerical model to study the origin of the low pressure in southern Alberta and its effects on patterns of regional groundwater flow over the past 5 m.y. The model accounts for changes in basin topography, conduction and …

Sedimentary basin evolution and structural compartmentalization in the northernmost Andes : Eastern Cordillera and Magdalena Valley, Colombia
… is recorded in Mesozoic to Cenozoic clastic basin fill along the Middle Magdalena Valley (MMV) and Eastern Cordillera (EC) fold-thrust belt of Colombia. The Volador study area (5.5-6.0 °N) displays structures that pre-date and post-date an Eocene regional unconformity. The contrasting …

Stratigraphic partitioning and reservoir distribution of the Late Devonian to Early Mississippian Exshaw Formation, Western Canada Sedimentary Basin.
… black shale reservoir within the Western Canada Sedimentary Basin (WCSB) that accumulated as an organic-rich basinal mudrock within a tectonically extensional region prone to horst and graben structures. This study characterizes sedimentologic and stratigraphic controls on Exshaw reservoir …

Numerical Modeling as a Means to Enhance Genetic Sedimentary Basin Interpretation : A Case Study of the Southern Cantabrian Basin (NW Spain)
… the development of the Southern Cantabrian Basin (NW Spain). A sedimentological and sequence stratigraphic model was established for the syn-orogenic Carboniferous basin fill, and subsequently analyzed and calibrated by a combined approach of reverse basin and stratigraphic forward …

A Comparative Study of Silicified Rock Reservoir in Shunnan 4 well of Tarim Basin with Hydrothermal Chert Reservoir of Parkland Gas Field in Western Canada Sedimentary Basin
… area which is located in the center of Tarim Basin, northwest China. Comparing to previous work about the silicificaition, much more detailed petrographic descriptions have been carried out in this study. The most important diagenetic features to the silicification are identified including …

Tectonics of the Uinta Recess in the Sevier Fold-Thrust Belt, Utah
… marked an abrupt change in the thickness of the sedimentary basin in which the fold-thrust belt formed. Basin geometry, in turn, was affected by reactivation of a long-lived basement fault system. Abrupt thickening of sedimentary strata to the south of this fault zone led to the development of …

An aqueous geochemical and hydrologic study of the springs and wells of the Sevilleta National Wildlife Refuge : evaluating hydrochemical pathways
… while others have proposed that upwelling sedimentary basin brines at interbasin constrictions represent a significant salinity input to the modern Rio Grande. This study (a) provides the first hydrochemical data on a comprehensive suite of springs and wells, and (b) tests and refines …

Thermal history model of the Williston Basin
… that affect the subsurface temperature of a sedimentary basin were investigated by empirical and analytical methods. A review of thermal-mechanical models suggests that the Williston Basin was formed by more than one mechanism. The Williston Basin may have been initiated by a thermal event …

Tectonic Exhumation and Climate Driven Erosion in Extensional Mountain Blocks: Two Examples from California, USA
… mass fluxes from extensional mountains blocks to sedimentary basins over 104-5 yr timescales is debated. In the eastern California-Walker Lane shear zone, exposures of sedimentary basin fill allow inversion of erosion- and sediment-flux rates from a linked catchment-fan system within an …

Hydraulic Fracturing and Flow-back Simulation in Unconventional Tight Reservoirs
… tight reservoirs in Western Canadian Sedimentary Basin (WCSB). It is important to understand hydraulic fracture propagation mechanism, effects of their properties and controlling factors affecting flow-back recovery. In this thesis, based on tight reservoir models in WCSB, firstly we …

The sequence stratigraphic evolution of the Sturgeon Lake bank, central Alberta, Canada and its regional implications.
… platform located within the Western Canada Sedimentary Basin (WCSB). Stratigraphic correlation of the Leduc Formation across the WCSB reveals a dominantly backstepping stratal geometry. The Sturgeon Lake South bank complex is composed of 12 retrogradationally stacked depositional sequences. …

Spatial heterogeneity in isotope and biomarker distributions : insights from the End-Devonian OAE in Western Canada.
… element geochemistry across the Western Canada Sedimentary Basin (WCSB) delves into the complex interactions between nutrient cycling, primary productivity, and organic matter preservation in marine ecosystems, with a particular focus on the Late Devonian period, where similar perturbations of …

Compaction-Driven Groundwater Flow and Heat Transfer in Intracratonic Sedimentary Basins and Genesis of the Upper Mississippi Valley Mineral District (Hydrology, Migration, Petroleum, Ore Deposits, Numerical Models)
… flow and associated heat transfer in evolving sedimentary basins. A calculation of compaction-driven flow during evolution of an idealized intracratonic sedimentary basin including a basal aquifer predicts slow groundwater movement over long time periods. Fluids in shallow sediments tend to …

The age, stratigraphy, and tectonic provenance of clastic deposits in the western Bikou terrane, southwestern Qinling Mountains, China
… metamorphic assemblage of igneous and clastic sedimentary rocks located adjacent to the northern margin of the South China Plate. The age and tectonic setting of clastic deposits within the Bikou terrane have long been controversial, with age estimates ranging from Lower Proterozoic to Late …

Petrology, geochemistry, diagenesis and depositional environment of the Upper Devonian - Lower Carboniferous Exshaw Formation, northwestern Alberta.
… heavy oil accumulations in the Western Canada Sedimentary Basin. The development of organic-rich deposits has been the center of much controversy as of late, since there are a number of depositional and paleo-oceanographic conditions responsible for their formation. This has led to various …

Geology, paragenesis, and geochemistry of sphalerite mineralization at the Young mine, Mascot-Jefferson City zinc district, East Tennessee
… tectonic activity and expulsion of fluids from a sedimentary basin to the southeast. Episodic dolomitization in the vicinity of the ore bodies both predated and accompanied sphalerite deposition. Dolomite and other minor gangue phases deposited concurrently with sphalerite. Fluorite, calcite and …
