The Late Permian Betts Creek Beds form a succession of coal-bearing alluvial-coastal plain sediments in a basin marginal setting within the northeastern Galilee Basin, Queensland, Australia. The unit is ~ 50–60 m in thickness at Porcupine Creek National Park where outcrop is laterally continuous for several kilometers. Eight facies have been identified within the formation and can be grouped in...

A large ice-dammed lake drained catastrophically into Lake Tuborg, Ellesmere Island, beginning on 25 July 2003. Limnological, sedimentological, and hydrological parameters were recorded before, during, and after this event. For several weeks prior to the jökulhlaup, water overtopped the ice-dammed lake and flowed into Lake Tuborg’s freshwater basin. A shallow sill separates the freshwater basin...

During the sedimentary period of Saertu reservoir on western slope northern Songliao basin, delta front and shore-shallow lake subfacies are mainly developed, which have characteristics few sandstone layers thin single layer thickness. The lithology or interlayer can not be distinguished clearly by seismic response conventional section, it is difficult to identify them. Geophysical channel sand...

Ordination is the name given to a group of methods used analyse multiple variables without preceding hypotheses. Over last few decades, use these in Earth science general, and notably analyses sedimentary sources, has dramatically increased. However, with limited resources oriented towards scientists on topic, application ordination analysis at times suboptimal misuse by authors can occur. This...

Abstract The paper presents a study of Lower Carboniferous (Visean) clastic sequence commonly called Bobrikovsky Formation, deposited in the Volga-Ural Petroleum Province, Orenburg Region. Our investigation included sedimentological description core samples from hydrocarbon wells and well log correlations. Facies were identified by patterns calibrated sedimentology. Formation is proposed to be ...

I am delighted to announce completion of the second issue of the new journal of “Geopersia”, a product of the new era of replacing the Persian language journals with specific English-language ones. Our purpose is to provide a journal that offers a multi-disciplinary analysis of issues concerning Geology subjects (i.e. sedimentology, stratigraphy, paleontology, Petroleum Geology, Engineering Geo...

This study was performed to recognize the loess texture in Golestan Province, Iran using the microstructure analysis according to the electron microscopic images. Loess microstructure study allows for investigating the characteristics of particle shape, fabric, cement and porosity in microscopic images. In recent years, computer analysis has been replaced with manual calculation due to its high...
