geomorphosites or special geomorphologic sites are new concepts which have entered tourism literature with anemphasis on special sites. basically, the goal for discussing such concepts is to identify landforms with specialimportance on understanding the geomorphologic structure of a region and their scientific, ecological, cultural,aesthetic, and economical values. generally, they are used for ...

Misho granitoid pluton is exposed at the North Western part of the Misho Mountains and at the South Western part of the Marand compresional depression. The minerals in the rocks of this pluton include unhedral to sub – hedral quartz, K – feldspar both as microcline with tartan twinning and  sub - hedral to unhedral orthoclase, two generations of biotite and zircon, subhedral to euhedral plagioc...

The Tang Zagh iron deposit is located about 117 km Northeast of Bandar Abbas, Hormozgan Province in the structural folded-thrusted zone of the Zagros basin. Iron mineralization occurs in the form of iron oxides (hematite) within the salt dome and/or in fractures and between the layers of the younger strata with the Tertiary age. Based on the microscopic studies, dolomitic fragments of the host ...

Interpretation of reflection seismic profiles, sequential restoration, and physical modelling are presented to understand the kinematics salt flow diapirism in Eastern Persian Gulf, offshore Southern Iran. Salt tectonics this area result from overlapping Ediacaran–Early Cambrian Hormuz Salt, which is regionally present, Oligocene–Early Miocene Fars locally developed. The salts began flowing at ...

Abstract Generative potential and thermal maturity for Upper Palaeozoic source rocks from the south-eastern edge of Precaspian Basin were determined using Rock–Eval. A high hydrocarbon rock generative degree Lower Permian, Mid-Carboniferous strata have been revealed based on 39 samples. TOC values 0.4–5.5% obtained mature rocks. Integrated geochemical analysis Rock–Eval studies combined with 1D...

Abstract This paper presents radon flux profiles from four regions in Schleswig–Holstein (Northern Germany). Three of these are located over deep-rooted tectonic faults or salt diapirs and one is an area without any halokinetic activity, but with steep topography. Contrary to recently published studies on spatial patterns soil gas concentration we measured into the atmosphere. All devices each ...

The interactions between salt diapirs, thrust welds and thrusts in contractional belts are poorly understood due to, first, the inability of seismic data to distinguish or resolve associated sub-resolution deformation, second, paucity good field examples. Warraweena area Northern Flinders Ranges South Australia contains examples Neoproterozoic Early Cambrian squeezed diapirs linked by steep rev...

Abstract Hormuz salt formation is considered the origin of evaporated deposits in Zagros and its ductile behavior has been known as reason for inhomogeneous deformation Zagros. However, our knowledge about this limited to domes on surface. In study, local earthquakes recorded by a temporary dense seismological network 17 stations, deployed southern margin Simply Folded Belt (SFB) southwestern I...
