The geocentric realm of tectonics changed with the dawn of robotic exploration of the other bodies of the solar system. A diverse assortment of tectonic landforms has been revealed, some familiar and some with no analogues to terrestrial structural features. In this chapter, we briefly introduce some of the major topics in the book. The chapters review what is known about the tectonics on Mercu...
Abstract The Southern Andes are regarded as a typical subduction orogen formed by oblique plate convergence. However, there is considerable uncertainty to how deformation kinematically partitioned in the upper plate. Here we use analogue experiments conducted MultiBox (Multifunctional Box) apparatus investigate dextral transpression between 34 °S and 42 °S. We find that our models caused mainly...
Tectonic geomorphology is part of Earth Sciences, which deal with study of the interaction of tectonic and geomorphology. In other words it studies the effective tectonic processes in forming and changing the landforms. Geomorphic and morphometric indicators are suitable tools to the morphotectonic analysis for different areas. These indicators are used as the base tool to identify and recognit...
The population of Rudbar in northern Iran, is due to Steep slopes of topography, Sloping Loose Materials, active tectonic phases, Construction of roads and railways, from areas prone to landslide events .In this reaserch, in the first phase, based on ground surveys, a geologic map of 1: 25,000, satellite images and other data of Rudbar region, range and status of landslides of the region were ...
Based on new structural, petrological and U-Th-Pb geochronological data, a reappraisal of the Variscan tectono-metamorphic history Pelvoux Massif (External Crystalline Massif, French Alps) is proposed with aim to understand flow pattern kinematics partially molten crust Eastern Shear Zone. The consists high-grade metamorphic rocks middle lower crust, mostly migmatites, that record prominent syn...
The Khoy Ophiolitic Complex (KOC) as a part of Tethyan, Izmir-Ankara- Erzincan and Bitlis-Zagros sutures of South East (SE) Turkey is broadly exposed around Khoy region (NW Iran). This complex comprises dismembered fragments of mantle lithosphere, obducted oceanic lithosphere and parts of volcanic arc remnants. The Khoy Ophiolitic Complex can be structurally divided into two major eastern and w...
Basalts in the Gasht-Masuleh area crop out in the SW Fuman, Gilan Province, and are exposed in the Jurassic and Late Cretaceous units in this area. Whole rock chemistry shows that the rock samples have Mg numbers between 30 and 31.7. Rare earth element patterns (REE) indicate light REE (LREE) enrichment and heavy REE (HREE) depletion (LaN/YbN= 7.7-9.8). Nb, Ta and Ti negative anomalies in primi...
