A prominent west-dipping reflection that can be traced in seismic-reflection profiles over an area of 7000 km beneath the Sevier Desert basin of west-central Utah is generally referred to as the Sevier Desert detacbment and is widely regarded as one of tbe best examples of an upper-crustal low-angle normal fault. The absence of evidence for fault-related deformation in drill cuttings and core f...

Recent years have witnessed a rapid growth of Internet channels due to the advance of information technology. From the consumers' viewpoint, however, this e-business revolution gives rise to an additional concern regarding the quality risk. Consequently, Internet sellers typically offer returns policies, and these returns policies vary across industries and stores. In this paper, we investigate...

Estimation of petrophysical properties of the rock formations played decisive role in all the processes of petroleum exploration. The Cambrian sequence is well established as reservoir rocks in the various parts of the world from where petroleum is being tapped. The Cambrian sequence has been encountered in the Potwar area and limited petroleum is being produced from the Adhi Oil Field. The Khe...

[1] Sediment fans are a potentially useful and underexploited recorder of Earth’s climatic and tectonic history, but historical observations have led to conflicting views on the importance of tectonic, climatic, and lithologic variables in controlling fan morphology and deposition. A one-dimensional model of a sediment fan and its associated catchment is used to explore the sensitivity of such ...

The Upper Mississippian Hinton, Princeton, and Bluestone formations of southern West Virginia constitute a westwardly thinning wedge of strata that filled the central Appalachian basin over a ~7 million year time interval. Up to 17 unconformity bounded, transgressiveregressive sequences comprise the study interval in the basin depocenter. Five sequence types are recognized based upon the degree...

Discovery of fossils of the Ediacara biota near the top of the Spitzkopf Member at farm Swanpunt extends the known range of these remains in Namibia more than 600 m to near the sub-Cambrian unconformity. The fossiliferous beds occur approximately 100 m above a volcanic ash dated at 543 +/- 1 Ma, and thus may be the youngest Proterozoic Ediacara-type fossils reported anywhere in the world. Fossi...

In this work, we report the first palynological age for base strata of Silves Sandstones Group in Algarve Basin, located Southern Portugal. The group is oldest sedimentary unit Basin and was deposited unconformably over late Pennsylvanian turbidites Mira Formation, which were folded faulted during Variscan Orogeny. comprises a detrital red bed succession, representing earliest phase sedimentati...

Abstract Mountain building and the rock cycle often involve large vertical crustal motions, but their rates timescales in unmetamorphosed rocks remain poorly understood. We utilize high-resolution magneto-biostratigraphy backstripping analysis of marine deposits an active arc-continent suture zone eastern Taiwan to document short cycles oscillations. A basal unconformity formed on Miocene volca...
