The topography of a catchment has a major impact on the hydrological, geomorphological. and biological processes active in the landscape. The spatial distribution of topographic attributes can often be used as an indirect measure of the spatial variability of these processes and allows them to be mapped using relatively simple techniques. Many geographic information systems are being developed ...

Integration of ichnologic, sedimentologic, and stratigraphic studies of cores from Lower Pennsylva-nian oil and gas reservoirs (lower Morrow Sandstone, southwest Kansas) allows researchers to distinguish between estuarine-and open-marine deposits. This study represents one of the first published ichnologic analyses of a Paleozoic reservoir and, therefore, provides a unique opportunity to test t...

electro-facies is a unit of the vertical sediments sequence on the wire-line logs that can be differentiated from the upper and lower units. for detection of the electro-facies interval in kangan and upper dalan formations in south pars gas field, wire-line log and core data analysis (wells a, b, c and d) were used. note, only core data analysis in well a were available. first, thin-sections st...

Palimpsests are large, circular, low-relief impact scars on Ganymede and Callisto. These structures were poorly understood based on Voyager-era analysis, but high-resolution Galileo images allow more detailed inspection. We analyze images of four Ganymedean palimpsests targeted by Galileo: Memphis and Buto Faculae, Epigeus, and Zakar. Ganymedean craters and Europan ring structures are used as t...

The aim of this research was to accurately measure the surface of the semi lunar articular surface of the pelvis (facies lunata acetabuli) and the variability of the acetabular geometry, as well as to determine the correlation between measured parameters. 30 macerated anatomical specimens of pelvic bones were measured. The radius and depth were measured in the classical way, while cartilaginous...

Within fluvial systems, the spatial variability of geomorphological characteristics of stream channels and associated streambed properties can affect many biogeochemical processes. In agricultural streams of the midwestern USA, it is not known how geomorphological variability affects sediment denitrification rates, a potentially important loss mechanism for N. Sediment denitrification was measu...

The occurrence of power law relationships in the spatial distribution of sedimentary lithotopes has been identified in both modern and ancient carbonate depositional bodies. In this study, facies patterns and their spatial relationships are investigated quantitatively in an Arabian Gulf shallow subtidal carbonate ramp setting, using a synergy of IKONOS satellite imagery and vessel-based acousti...

6 [1] Clay-rich mass transport deposits (MTDs) in the Ursa Basin, Gulf of Mexico, record 7 failures that mobilized along extensional failure planes and transformed into long runout 8 flows. Failure proceeded retrogressively: scarp formation unloaded adjacent sediment 9 causing extensional failure that drove successive scarp formation updip. This model is 10 developed from three-dimensional seis...

Trichoepithelioma is a benign tumor of follicular unit. It has been rarely described as the cause of leonine facies. We are presenting a classical case of multiple familial trichoepitheliomas (MFTs) with characteristic histopathological features leading to leonine facies.

Identification of specific environments of deposition represented by black shales has been a traditional puzzle for geologists. The present study was undertaken to see whether sedimentary structures, especially biogenic structures, could be used to subdivide the inclusive term "black shale facies." Because of the prevalence of infauna, modern marine muds are typically bioturbate; only where ani...
