Understanding how changes in fluvial and marginal marine architecture correlate with shifts in marine shoreface architecture is a crucial step to understanding the effect of relative sea level changes on terrestrial sedimentary systems. Three measured sections (each >230 m), 2367 paleocurrent measurements, and examinations of lateral facies relationships were made over 3 km of continuous outcro...

This paper proposes a knowledge model for representing concepts that requires pictorial as well as conceptual representation to fully capture the ontological meaning. The model was built from the proposition of pictorial primitives to be associated to the original conceptual primitives. The formalized pictorial content is then used to provide an organization to the domain, based on the visual c...

FIG. 1.—Generalized location map of Big Cottonwood Canyon, southeast of Salt Lake City. Circled numbers refer to measured sections of: 1, Storm Mountain (Fig. 7); 2, S-curve (Fig. 9B); 3, Moss Ledge (Fig. 9A). ABSTRACT: The Mesoproterozoic to Neoproterozoic Big Cottonwood Formation of north-central Utah contains some of the oldest known (; 900 Ma) examples of cyclic tidal rhythmites. Despite mi...

From Oligocene to Recent times a series of tectomcally controlled coastal embayments fonned on the Pacific fore-arc side of the southern Central American island-arc system. Each of these basins shows characteristic stratal geometries and facies distributIOns reflecting the complex interaction of changes of sea level. volcaniclastic input. and tectonic activity (subsidence, uplift). Sequential s...

The investigation and exploration of potential deep geothermal systems is based on detailed knowledge of their distinct reservoir characteristics. This is especially important in the exploration of potentially engineered geothermal systems and of mid to low enthalpy reservoir formations in greater depths, resp. In the early stages of geothermal reservoir exploration, characterization of the res...

The present research focuses on a detailed facies description and interpretation of five alluvial fans of the Qazvin Plain. Beside the tectonic activity that leads to the localization of the fans on the northern margin of the Qazvin Plain, the climate has a significant role in the occurrence of their facies. The alluvial fans are divided into three facies groups: group 1, group 2, and group 3. ...

primary sedimentary and secondary structural and diagenetic processes are responsible for heterogeneity in carbonate reservoirs and recognition of these factors is very essential subject in modeling these reservoirs. image logs are very useful for identification of structures and small scale sedimentary features. in this research, using image analysis of formation microimager log (fmi) in a dri...

Sedimentological processes often result in complex three-dimensional subsurface heterogeneity of hydrogeological parameter values. Variogram-based stochastic approaches are often not able to describe heterogeneity in such complex geological environments. This work shows how multiple-point geostatistics can be applied in a realistic hydrogeological application to determine the impact of complex ...

Archean volcanic rocks in the mafic-dominated, ca. 2.66–2.69 Ga Point Lake and Beaulieu River belts, Slave Province, Northwest Territories, are significant in demonstrating the facies that characterize specific portions of pillow volcanoes or seamounts, irrespective of tectonic setting. Three distinct localities mapped in detail display facies consistent with: (1) proximal, deep-water, (2) medi...

Sarvak formation, with the middle cretaceous (Cenomanian) age, is one of the stratigraphic units of the Bangestan group in the southern Iran. The carbonate rocks of this formation form the reservoir rock in the study field. Generally, Sarvak formation is subdivided into three members including Mishrif, Khatiyah, and Maddud in the Persian Gulf, and the average thickness of the reservoir unit (i....
