We argue that the observed conduit‐barrier behavior of fault zones in siliciclastic sedimentary aquifer systems can be understood by considering a strongly anisotropic hydraulic structure fault. Hydraulic anisotropy is expected from variety mechanisms including clay‐smearing, drag sand, grain re‐orientation and vertical segmentation plane. In this paper, we present an algorithm to predict zone width, lithological heterogeneity anisotropy. Estimation these parameters based upon amount throw...
HYDROTECTONIC MODELS OF BURIAL DIAGENESIS IN PLATFORM CARBONATES BASED ON FORMATION WATER GEOCHEMISTRY NORTH AMERICAN SEDIMENTARY BASINS
Abstract A series of M b 3.8–5.5 induced seismic events in the midcontinent region, United States , resulted from injection fluid either into a basal sedimentary reservoir with no underlying confining unit or directly crystalline basement complex. The earthquakes probably occurred along faults that were likely critically stressed within basement. These located at considerable distance (up to 10 km) wells and head increases hypocenters relatively small (∼70–150 m). We present suite...
While the geomorphic consequences of Pleistocene megafloods have been known for some time, it has only in past 2 decades that hydrogeologists and glaciologists alike begun to appreciate important impact ice sheet–aquifer interactions had controlling subsurface flow patterns, recharge rates, distribution fresh water confined aquifer systems across North America. In this paper, we document numerous lines geochemical, isotopic, geomechanical evidence sheet hydrogeology We also review...
While the existence of relatively fresh groundwater sequestered within permeable, porous sediments beneath Atlantic continental shelf North and South America has been known for some time, these waters have never assessed as a potential resource. This water was likely emplaced during Pleistocene sea-level low stands when exposed to meteoric recharge by elevated in areas overrun Laurentide ice sheet at high latitudes. To test this hypothesis, we present results from high-resolution...
Mathematical modeling of coupled groundwater flow, heat transfer, and chemical mass transport at the sedimentary basin scale has been increasingly used by Earth scientists studying a wide range geologic processes including formation excess pore pressures, infiltration‐driven metamorphism, flow anomalies, nuclear waste isolation, hydrothermal ore genesis, sediment diagenesis, tectonics, petroleum generation migration. These models have provided important insights into rates pathways migration...
A high‐resolution stratigraphic image of a flume‐generated deposit was scaled up to sedimentary basin dimensions where natural log hydraulic conductivity (ln(K)) assigned each pixel on the basis gray scale and end‐members. The synthetic ln(K) map has mean, variance, frequency distributions that are comparable alluvial fan deposit. geostatistical analysis conducted selected regions this containing fluvial, fluvial/floodplain, shoreline, turbidite, deepwater facies.

Abstract First reported in the 1960s, offshore freshened groundwater (OFG) has now been documented most continental margins around world. In this review we compile a database documenting OFG occurrences and analyze it to establish general characteristics controlling factors. We also assess methods used map characterize OFG, identify major knowledge gaps, propose strategies address them. global volume of 1 × 10 6 km 3 ; predominantly occurs within 55 coast down water depth 100 m. is mainly...
Abstract Although offshore freshened groundwater (OFG) systems have been documented in numerous continental margins worldwide, their geometry, controls and emplacement dynamics remain poorly constrained. Here we integrate controlled-source electromagnetic, seismic reflection borehole data with hydrological modelling to quantitatively characterise a previously unknown OFG system near Canterbury, New Zealand. The consists of one main, two smaller, low salinity bodies. main body extends up 60...

The hydrodynamic consequences of a glaciation/deglaciation cycle within an intercratonic sedimentary basin on subsurface transport processes is assessed using numerical models. In our analysis we consider the effects mechanical ice sheet loading, permafrost formation, variable density fluids, and lithospheric flexure solute/isotope transport, groundwater residence times, transient hydraulic head distributions. simulations are intended to apply, in generic sense, basins that would have been...
Abstract This study reviews and synthesizes the results from geochemical isotopic case studies across Europe, North America, Antarctica, Greenland to evaluate effects of Pleistocene glaciation on continental‐scale groundwater circulation in sedimentary basins. The most effective studies, terms delineating high‐resolution records paleorecharge aquifers, combine solute chemistry, stable isotopes water, age tracers, dissolved noble gases. Some lowest δ 18 O values (−22‰), gas temperatures...

Anomalously high (up to +8°C) and low (−2°C) groundwater temperatures, as compared undisturbed geothermal profiles, have been observed in unconsolidated siliciclastic aquifers off‐set by normal‐faults the Lower Rhine Embayment, Germany. High hydraulic head gradients, induced pumping, over same faults suggest that they form effective barriers lateral flow. Numerical analysis of data presented here shows thermal anomalies can be explained under assumption a sub‐vertical pathway is connecting...
Abstract The Paradox Basin in the Colorado Plateau (USA) has some of most iconic records paleofluid flow, including sandstone bleaching and ore mineralization, hydrocarbon, CO2, He reservoirs, yet sources fluids responsible for these extensive fluid-rock reactions are highly debated. This study, first time, characterizes within basin to constrain emergent behavior flow resulting rock records. Major ion isotopic (δ18Owater; δDwater; δ18OSO4; δ34SSO4; δ34SH2S; 87Sr/86Sr) signatures formation...
While it has been known for some time that reducing fluids have bleached red beds adjacent to fault zones and regionally across the Colorado Plateau, volumes of expelled along faults never quantified. We developed applied a suite one-dimensional hydrologic models test hypothesis internally generated, migrated up sub-basin bounding Paradox Basin overlying beds. The internal fluid driving mechanisms included are mechanical compaction, petroleum natural gas generation, aquathermal expansion...

Recent advances in marine electromagnetic surveys have allowed geophysicists to interpret and map offshore freshwater resources with unprecedented resolution test inferences regarding onshore-offshore hydrologic connections. To date, however, little is known about the timing or isotopic composition of this unconventional water resource. Here, we reconstructed Pleistocene hydrogeology U.S. Atlantic continental shelf using a cross-sectional paleo-hydrogeologic model explore possible mechanisms...

Gas highly dependent on rock permeability which notoriously difficult determine experimentally field due a potentially large dependence scale over measurements are made.
