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...

Introduction: Recent reexamination of the fan-shaped deposits on the NW flanks of the Tharsis Montes and Olympus Mons has revived earlier interpretations [e.g., 13] that these deposits could have a glacial origin. New spacecraft data and improved understanding of cold-base glacier behavior has led to the interpretation that these features are the depositional remains of cold-based tropical moun...

This paper presents for the first time a detailed study on information content of X-band single-pass interferometric spaceborne SAR data with respect to snow facies characterization. An approach for classifying different snow facies of the Greenland Ice Sheet by exploiting X-band TanDEM-X interferometric synthetic aperture radar acquisitions is firstly detailed. Large-scale mosaics of radar bac...

This research successfully extends a deterministic, physically-based inverse theory that is capable of simultaneous parameter and boundary condition estimation to uncertainty quantification in inverting steady-state groundwater flow in a two-dimensional aquifer with facies heterogeneity. Using facies and dynamic flow measurements sampled at wells as observations, a stochastic subsurface data in...

The Main Glauconite Bed (MGB) is a pelleted greensand located at Stone City Bluff on the south bank of the Brazos River in Burleson County, Texas. It was deposited during the Middle Eocene regional transgression on the Texas Gulf Coastal Plain. Stratigraphically it lies in the upper Stone City Member, Crockett Formation, Claiborne Group. Its mineralogy and geochemistry were examined in detail, ...

Abstract To guide future exploration, this predominantly field based study has investigated the structural evolution of central Kiruna area, type locality for iron oxide-apatite deposits that stands a significant amount European ore production. Using combination geologic mapping focusing on structures and stratigraphy, petrography with focus microstructures, X-ray computed tomography imaging su...

This study was done on 65 isolated pelvic bones, These cadavers belonged to adult people of mature and old age, and they had no pathological changes. These measurements were performed on osteological collection of Department of Anatomy Drago Perović. Many geometrical parameters of facies auricularis were measured, which we considered important for further studies, simulations of joint's action,...

Reservoir heterogeneities exist at several length scales. Reservoir properties will depend on the scale that we are analysing on the reservoir (from core to grid block). Facies are normally identified in cores and classified based on microscopic and small scale features such as lithology, grain size, texture, sedimentary structure, colour and fossil content. However, facies information is only ...

A detailed outcrop and sub-surface analysis was completed on the Peay Member sandstone (Frontier Formation) in the northeast Bighorn Basin, Wyoming, building on previous work by Clark (2010) and Hutsky (2011). Regional correlations reveal the sandstone body to be digitate in planform geometry, elongate along depositional dip, and restricted across depositional strike. It is interpreted to be th...
