In the Cheshmeh-Bid district of Khajeh-Jamali ophiolitic massifs (Southern Iran), mantle peridotites are intruded by abundant pyroxenite dykes. A few these dykes remarkable for occurrence native copper associated with development a metasomatic reaction zone. The progressively reacted, from their margins towards center, an amphibole + antigorite selvage, followed centimeter-thick clinopyroxene a...

Sandstone intrusions are found in all sedimentary environments but have been reported most commonly from deep-water settings. They also appear to be more frequently developed in tectonically active settings where applied tectonic stresses facilitate development of high fluid pressures within the sediments. A variety of mechanisms have been cited as triggers for clastic intrusions. These include...

As problems such as difficulties in securing stable energy resources and global warming due to the emission of greenhouse gases use fossil fuels have emerged, interest development renewable is increasing. Since tidal phenomenon has a regularity that occurs regularly with certain period, it possible predict accurately advance, which advantage terms recovery. Therefore, various methods been devis...
