Rocks and fossils do not come with labels informing us of their age. They must be understood in light of their geologic context, and interpreted within a worldview. Unfortunately, my evolutionary colleagues are often so dominated by uniformitarian brainwashing they can't objectively understand young-Earth evidence. Nevertheless, some of the evidence is clear and open for all to see. One such cl...

The Lubok Antu Mélange is exposed along one of the most important tectonic lineaments, Lupar Line in Sarawak, Borneo. However, depositional age poorly known, and no provenance studies have been conducted so far. Here, we use geochemical, Nd isotopic detrital zircon UPb analyses samples from to constrain routing order better understand Borneo's evolution history. Bulk rock geochemistry reveals t...

Abstract The Cretaceous sediments in southwestern Nigeria are host to one of the largest bitumen deposits world. In current paper, an integrated study on sedimentology, palynology, and applied petroleum geochemistry Maastrichtian-Paleocene Araromi Formation was used determine depositional environments hydrocarbon potentials formation eastern Dahomey Basin. Four sedimentary lithofacies were iden...

The studied area located in south and south western Arak town and are the part of Sanadaj-Sirjan Zone. The plutonic rocks in Astaneh and Boroujerd areas are quartz diorite, granodiorite and monzogranite. In addition to plutonic rocks, subvolcanic rocks of rhyodacite composition are present in Astaneh area. In general, in these areass mineral assemblage is the same in different units. The common...

The study area is located in the south of Qushadagh mountain range, in the north of Asbkhan village, Heris township. In terms of structural geology of Iran, this area is located in the main zone of Central Iran and Alborz-Azerbaijan sub-zone. The geological units of the region are including Eocene igneous and pyroclastic rocks with combination of andesitic, trachyandesitic, basaltic, tuffic and...

The East Chia Sabz site is located on the bank of the Seymareh River in the middle of the Zagros Mountain chain. The site is among the few examples of the acramic Neolithic sites of the 8th millennium B.C. of Zagros which was archaeologically investigated during the rescue archaeological studies of the Seymareh dam. Numerous bullet-shaped cores were unearthed during the archaeological excavatio...

protein serine/threonine kinase (ROCK), is one of the central regulatory molecules for cytoskeleton control and cell adhesion process. ROCK also involves in other cell functions such as apoptosis and tumor invasiveness. Rho kinase is thought to play an important role in a variety of cellar functions such as stress fiber formation, focal adhesion formation, cell aggregation, cell morphology, cyt...
