Occurance of Selenium in Sedimentary Rocks
<p>The investigation of Selenium in Sedimentary Rocks was stimulated by Mr. Kohanowski who had two samples of sedimentary material that were believed to contain selenium.</p> <p>As not too much information is available or known about selenium minerals Mr. Kohanowski thought it would be educational …

The sedimentary record of seafloor uplift
… of the seafloor and subsurface influences sedimentary systems, hydrocarbon distribution, paleoclimate archives, and poses significant geohazard risks. This thesis investigates the different origins, evolution, and impacts of various uplifting mechanisms on deep-water sedimentary records …

Volcanic and sedimentary processes in phreatomagmatic volcanoes
… and burial beneath later lavas. In contrast the sedimentary structures petrography, morphology and grain size characteristics of diatreme tuffs are shown to be often sufficiently well preserved to permit the identification of their original surface volcanoes and their eruptive histories.

Dynamical Sedimentary Models of Shallow Marine Environments
… a contribution of quantitative, dynamical sedimentary modeling to the analytical understanding of sedimentary processes in shallow marine environments. The dynamical sedimentary models in this treatise numerically simulate the sedimentary processes from an event time scale, based on the …

Construction Site Sedimentary Pollution in a Watershed
… indicate integration of runoff processes and sedimentary pollution, which enhance the determination that; sediments from construction sites were sources of pollution to watersheds. In addition, the (pollutants) mica, bitumen and paint were present in soil samples from the construction sites …

Stratigraphic sedimentary inversion using paths in graphs
The problem of Stratigraphic Sedimentary Inversion consists of analysing quantities of given sediments deposited in sampled regions of a depositional space and calculating the total volumes that are necessary to match the sampled data in a forward depositional simulation. This is a central problem …

Digital Simulation of Compaction in Sedimentary Sequences
… the excess pore pressure in nonhomogeneous sedimentary sequences is developed. In this model, physical properties of fluid and sediments are considered to vary with temperature and pressure. The Crank-Nicolson finite difference method is used to solve the partial differential equations of …

A Glacial Sedimentary System in Northwest Spitzbergen
… conditions, and to aid interpretation of sedimentary structures within core sediments. Results of lichenometric survey of moraine ridges and pro-talus deposits in and around Signedalen were analysed using discriminant analysis, and compared with Werner's (1988) lichen growth curve in order …

Comparison of Bedding Thickness in some Sedimentary Materials
<p>Geologists, particularly stratigraphers and sedimentologists, utilize terms to describe bedding thicknesses such as "thin", “medium" and "thick" that are poorly defined. Kelley, who discussed the early unsuccessful attempts to define bedding, believed that such terms should have an accepted …

Fault rock evolution and fluid flow in sedimentary basins
Structural studies have been undertaken in two extensional fault regimes associated with post-Caledonian basin-forming events in northern Scotland. A combination of detailed mapping and microstructural analysis has revealed the deformation processes and mechanisms involved in fault rock evolution …

Holocene sedimentary history of Chilliwack Valley, Northern Cascade Mountains
… that have detailed much of its Quaternary sedimentary history. In the present study this information is supplemented by reconstruction of the morphodynamic trajectory of the river valley though the Holocene Epoch, and development of a sediment transfer model that describes the relaxation …
