Biostratigraphy, lithostratigraphy, ammonite taxonomy and microfacies analysis of the Middle and Upper Jurassic of northeastern Iran
… thesis, the biostratigraphy, lithostratigraphy, microfacies, depositional environments and palaeobiogeography of these rocks are discussed with special emphasis on the abundant ammonite fauna. They constitute a more or less continuous sequence, being confined by two tectonic events, one at the …

Microfacies analysis of the lower paleocene beda formation in Western Concession 59 and Block 59F, Sirte Basin, Libya /
… been subdivided into twelve platformal carbonate microfacies. These microfacies are dominated by muddy carbonates, such as skeletal mudstones, wackestones, and packstones with dolomites and anhydrite. Rock textures, faunal assemblages and sedimentary structures suggest shallow, clear, warm waters …

Microfacies Analysis, Sedimentary Petrology, and Reservoir Characterization of the Sinbad Limestone Based Upon Surface Exposures in the San Rafael Swell, Utah
… unit in the San Rafael Swell permit detailed analysis of its vertical and lateral reservoir heterogeneity. Vertically, the Sinbad Limestone comprises three facies associations: (A) a basal storm-dominated, well-circulated skeletal-oolitic-peloidal limestone association, (B) a storm-dominated, …

Palaeoenvironmental analysis of the upper Cenomanian and lower Turonian limestone beds in the Sergipe Basin, northeastern Brazil, based on microfacies analysis, micropalaeontology and stable isotopes
Die Kalksteinschichten des oberen Cenoman- unteren Turon (mittlere Kreide) des Sergipe Beckens in Nordost-Brasilien, wurden bezüglich des Paläoenvironments und der Mikrofazies untersucht. Die Mikrofauna wurde auf ihre biostratigraphische Verwendbarkeit analysiert und zur Interpretation des …

ASPECTS OF THE MICROPALAEONTOLOGY AND STRATIGRAPHY OF CRETACEOUS SHELF CARBONATES FROM THE OMAN MOUNTAINS
… were prepared for micropalaeontological and microfacies analysis. The foraminifera, calcareous algae and calpionellids in each sample were recorded in order to provide a means of biostratigraphic subdivision, and together with microfacies analysis and sedimentological observations made in the …

Mikrofazies, Sedimentationsgeschehen und paläogeographische Entwicklung im Verlauf des oberen Viséums im Untergrund der Niederrheinischen Bucht und des Campine-Beckens
… Geverik (The Netherlands) were the subjects of microfacies analysis and stratigraphic, sedimentologic and petrologic examination. The examined core material of the Schwalmtal 1001 borehole has a V3b to lower Namurian age (foraminifer subzones Cf6ß-Cf7), the material of the Geverik-1 borehole has …

The Lower Carboniferous (Chadian-Brigantian) geology of shallow marine carbonate rocks in the central and southeast Irish Midlands and the Wexford Outlier
"This is the first comprehensive study, consisting of integrated petrographical, paleontological and geochemical analyses on the post-Waulsortian strata in the central and southeast Irish Midlands. This study reveals that the style of sedimentation and early diagenesis substantially influenced the …

A 7000 yr runoff chronology from varved sediments of Lake Mondsee (Upper Austria)
… deposition was analysed by a combined method of microfacies analysis via thin sections, Scanning Electron Microscopy (SEM), μX-ray fluorescence (μXRF) scanning and magnetic susceptibility. This approach allows characterizing individual detrital event layers and assigning a corresponding input …

Varve and event layer chronology of Lake Suigetsu (Japan) back to 40 kyr BP and contribution to the international consensus atmospheric radiocarbon calibration curve
… of past floods or earthquakes. A detailed microfacies analysis revealed three different types of event layers, two of which are described here for the first time for the Suigetsu sediment. The types are: matrix supported layers produced as result of subaqueous slope failures, turbidites …
