Sediment accumulation rates can be notoriously hard to measure over geomorphic timescales in coastal systems. Anthropogenic metals, if their provenance constrained, act as tracers and help build a much more detailed understanding of these processes on decadal/century timescales. Past industrial activity the history warfare along coast Normandy, France has been subject intense study due its significance historians, having site largest naval invasion during World War II. Previous publications...

Ancient sand-rich fluvial systems form critical subsurface reservoirs for hydrocarbon exploration, carbon storage and a variety of other uses; however, their complex architecture often hinders the generation accurate reservoir models. Detailed study analogous outcrop exposures is managing exploration risk developing efficient production strategies, providing detailed look at potential connectivity reservoir targets. The Late Triassic...

Building high resolution analog models based on outcrop exposures is a powerful tool for describing complex geologic systems. By creating detailed architectural models, we further our understanding of these sedimentological systems and increase ability to predict heterogeneity in the subsurface. These same methods can be applied overall evolution architecture fluvial worldwide, reservoirs across timeline. This study examines connectivity depofacies within Cretaceous lower Castlegate...

Abstract The hydrazine/thiocyanate system was found to be an excellent solvent for cellulose. solubility and solution properties were investigated. Even at room temperature, the combinations of hydrazine lithium, sodium, potassium thiocyanate had high dissolution power cellulose, up 18% (w/w) maximum, unrelated polymorph, whereas a combination with ammonium exhibited difference among celluloses I, II, III. effect temperature cycling rapid cellulose investigated thermodynamically. In these...

ABSTRACT Fine‐grained Palaeogene–early Neogene strata of the South Caspian basin, specifically Oligocene–Lower Miocene Maikop Series, are responsible for bulk hydrocarbon generation in region. Despite magnitude oil and gas currently attributed to source interval offshore, geochemical evaluation 376 outcrop samples from northern edge Kura basin (onshore eastern Azerbaijan) indicates that depositional conditions these proximal along margins were dominantly oxic mildly suboxic/anoxic throughout...

Abstract The dissolution of cellulose in solutions liquid ammonia and ammonium thiocyanate is discussed. Viscosity measurements on dilute this solvent over a range shear rates stresses are reported. A four‐bulb Ubbelohde suspended level viscometer was used for the measurements. Plots log [η] versus M gave Mark‐Houwink coefficients = 0.95 K 6.686 × 10 −5 at 25°C as dl/g.

Some outcrops adjacent to the 25-km (15-mi)-long salt weld in La Popa Basin, northeastern Mexico, are visibly stained and contain enrichment of organic carbon. Their presence, which is known only along northwestern part southwestern side weld, provides evidence for hydrocarbon migration weld. This distribution presumed be partially controlled by restricted source rock that generated hydrocarbons within salt-withdrawal basin southwest but may have been a previously existing wall, or formed as...

Abstract An analysis of the sedimentary fill a foreland basin can provide information on relative effect tectonics, base‐level fluctuations and climate during development. This study analyzes fluvial strata from upper Cedar Mountain Naturita formations mid‐Cretaceous Utah (USA) to determine effects spatial location within planform architecture. The results document consistent architecture across distal foredeep forebulge depozones flooding Western Interior Seaway suggesting that did not...

Abstract The melting temperatures of thermoreversible gels formed from solutions cellulose in liquid ammonia/ammonium thiocyanate mixtures were measured over a volume fraction range .01–.004. Three samples with M w ranging 1 × 10 5 to 1.64 used. findings show that the structural makeup is strongly reflected their time‐dependent behavior. reciprocal temperature nearly linear function logarithm concentration. relation between and gel was also linear.

Significant urban development surrounding the Gold Coast Broadwater and upper catchment has resulted in concerns about degrading water quality of estuarine system. The Seaway plays an important role exchange oceanic waters influencing intertidal region. Water within immediately adjacent was investigated three times at sample depths 13 locations. Conductivity, temperature, depth casts, total (nitrogen phosphorus) dissolved inorganic (NOx NH4 ) nutrients, fecal indicator bacteria were measured...

The Oligocene – Miocene Maikop Formation is the key source rock in South Caspian and Kura Basins. composed of a thick (up to 3 km) succession clay‐rich mudstones containing up 15% total organic carbon (TOC). Despite decades study, often lack precise age control strata rarely contain diagnostic microfaunal assemblages which can be used for dating, stratigraphic correlation, or constraining depositional setting. Using rhenium‐osmium geochronology, this study adds important numerical data...
