The instability and mobility of sand dunes is a major concern of planning and management in arid coastal plains. The aim of this study is to identify morphogenetic characteristics of sand masses and their locations, as well as to identify the processes that formed and transported them in the western part of the Makran coastal plain. Research data and tools were including spatial distributions o...

       The Ghaleh Ganj dioritic- quartz dioritic massifs, as a part of intrusive in the Makran zone show spheroidal weathering and exfoliation. This phenomenon is related to the development of micro-crack systems. Furthermore, various factors such as mechanical properties of rock-forming minerals, tectonic stresses, increasing volume during mineral weathering and earth surface temperature fluct...

In the Makran area, a wide accretionary wedge is originated by north-dipping subduction of Neo-Tethyan oceanic lithosphere. The rear represented North Domain that consists an imbricate stack tectonic units derived from closure basin. This basin opened southward Eurasia continental margin during Early Cretaceous. Bajgan Complex interpreted as Paleozoic or older metamorphic basement representing ...

earthquakes are a particular concern because of the serious hazard they present. the existence of seismicity patterns such as the foreshock and aftershock clusters, doughnut pattern, seismic quiescence etc show that the earthquake occurrence in the active tectonic regions is not random and clustering phenomena are obvious characteristics of these events in space and time. fractal analysis, as a...
