The western Tianshan high-pressure/low-temperature orogenic belt in NW China contains eclogite-facies metavolcanic rocks and omphacite-bearing blueschists. Previous Sm-Nd (omphacite, garnet, glaucophane, whole rock) and Ar/Ar (crossite) dating of eclogite-facies rocks has suggested an age of ca. 345 Ma as the best approximation for the timing of peak metamorphic conditions. The samples describe...

Identifying facies for classification for a seismic inversion project is an important step where one balances computational effort and the quality of the results. We propose a new measure to quantify the suitability of a given facies partition based on information theory. The results depend on a user-selected cutoff, and we propose a reasonable value for this constant. We also show the analysis...

As the reservoir and its attribute distribution are obviously controlled by sedimentary facies, facies modeling is one of important bases for delineating area high-quality characterizing parameter distribution. There a large number continental reservoirs with strong heterogeneity in China, geometry various microfacies relatively complex. The traditional geostatistics methods which have shortage...

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...

In the context of STRATAFORM and EuroSTRATAFORM, the long-term goal of this project is to contribute toward simultaneously understanding (i) short term oceanic processes that erode, transport and deposit sediment in the margin system and (ii) the creation of the preserved stratigraphic architecture, seafloor morphology and sediment facies on continental margins. In order for models at such disp...
