Aghajari Formation, known as Upper Fars Group, is developed throughout the Folded Zagros Zone and has a thickness of 2966 m in its type section in SW of Iran and 1473 m in the study area, located 20 km west of Shiraz. Aghajari Formation, in this area, consists of three major facies associations. These are "fine", "medium" and "coarse" grained terrigenous sediments, usually interpreted as channe...

A geophysical method of investigation has been deployed in order to give a quick overview the nature and rapidly changing subsurface lithologies that characterized Yikpata, Share, Kwara State, Nigeria. total nine (9) vertical electrical soundings (VES), using Schlumberger Array uniformly divided into three groups: basement, basement/sedimentary boundary sedimentary terrain, horizontal profiling...

Samples of sediments from beneath Ice Stream B (at camp UpB), West Antarctica, provide the first opportunity to study the relationship between sediment properties and physical conditions in a sub-ice-stream environment. Piston coring in holes bored by hot-water drilling yielded five 1–3 m long, undisturbed subglacial sediment cores. We analyzed granulometry, composition, and particle morphology...

Subseafloor sedimentary environments harbor remarkably diverse microbial communities. However, it remains unknown if the deeply buried fossils in these sediments play ecological roles in deep microbial habitats, or whether the microbial communities inhabiting such fossils differ from those in the surrounding sediment matrix. Here we compare the community structures of subseafloor microbes in co...

Sedimentological and geomorphological characteristics of coral reef islands are strongly related to past and recent boundary conditions such as the hydrodynamic regime, wind directions, sea-level fluctuations, and the ecological footprint of the surrounding reef complexes. Alterations in the physical, chemical, and biological boundary controls may affect the stability of reef islands. Additiona...
