Results are presented of the first airborne LiDAR survey ever flown in Europe for purpose mapping surface expression earthquake‐prone faults. Detailed topographic images derived from data Idrija and Ravne strike‐slip faults NW Slovenia reveal geomorphological structural features that shed light on overall architecture kinematic history both fault systems.

The distribution of landslides induced by the 2008 M w 7.9 Wenchuan earthquake was investigated following method Meunier et al. (2007) to examine relationships peak ground acceleration (PGA). Results suggest that landslide densities are quantifiably related PGA. Thresholds PGAcr for failure ![Graphic][1] average horizontal PGA and ![Graphic][2] vertical As with other earthquakes, earthquake‐triggered can be described two equations, based on area source densities, respectively. similar...
Phenocrysts in magmas are often assumed to be the product of crystallization directly from a host magma. However, decades research suggests that crystals carried (crystal cargo) far more complex. We test hypothesis textural and chemical characteristics phenocrysts (both native disaggregated crystal clots) andesitic dacitic lavas tephras can used develop models for spatial arrangement subcrustal magma systems their evolution over time. To do this, we use geochemical fingerprinting complex...
Abstract: The Palaeozoic–Mesozoic tectonic evolution of Central Asia, including the vast terrane collage that makes up Mongolia, has been a topic considerable debate. Oyut Ulaan Volcanic Group is sequence volcanic and sedimentary rocks in SE Mongolia forms southern part Devonian–Permian Saykhandulaan Inlier. Fieldwork traverses mapping have established four distinct formations record nature arc activity Asian Orogenic Belt during Carboniferous. Physical volcanological sedimentological...
Spectacular refolded folds clearly visible from space deform Permian turbidite successions in a 180 km 2 fault‐bounded compartment within the Beishan region of northwestern China. The formed after final terrane amalgamation Central Asian Orogenic Belt and record an important sequence intraplate deformation events central Asia during Late Permian‐Jurassic. fold interference patterns are dominantly Type refolds with kilometer‐scale wavelengths. They bounded to north south by regional E‐W...
Vegetation cover can affect the lithological mapping capability of space- and airborne instruments because it obscures spectral signatures underlying geological substrate. Despite being widely accepted as a hindrance, few studies have explicitly demonstrated impact vegetation on remote mapping. Accordingly, this study comprehensively elucidates multispectral data in Troodos region, Cyprus. Synthetic mixtures were first used to quantify potential might recognition different rock types. The...
The mechanism of continental growth Central Asia is currently debated between models invoking continuous subduction–accretion, or punctuated accretion due to closure multiple ocean basins. Ophiolites in may represent offscraped fragments an accretionary complex true collisional sutures. Bayankhongor ophiolite, a NW–SE-striking sublinear belt 300 km long and 20 wide, the largest ophiolite Mongolia possibly Asia. We present results first detailed structural lithological study ophiolite. area...
Abstract Restraining bend mountain ranges are fundamental orogenic elements in the Altai, Gobi Altai and eastern Tien Shan. In this paper, 12 separate restraining bends reviewed to identify common structural topographic characteristics. The occur one of three different tectonic settings: (1) strike-slip fault termination zones; (2) at a major where individual can be traced continuously from end range other; (3) two segments converge overlap. Fault maps reveal that they all flower or...
Abstract The Gobi Altai is an intraplate, intracontinental transpressional orogen in southern Mongolia that formed the Late Cenozoic as a distant response to Indo-Eurasia collision. modern range within crust constructed by successive terrane accretion and ocean suturing events widespread granite plutonism throughout Palaeozoic. Modern reactivation of kinematics Quaternary faults are fundamentally controlled Palaeozoic basement structural trends, location rigid Precambrian blocks, orientation...
The Archean and Paleoproterozoic São Francisco craton of eastern Brazil is surrounded on all sides by Brasiliano (=Pan African) orogens. N–NE trending orogen that separates the edge southern from Atlantic coast can be divided into largely greenschist amphibolite facies Araçuaı́ belt west granulite Ribeira east. A pronounced linear gravity magnetic anomaly, Abre Campo discontinuity, defines boundary between these two belts. We obtained Sm–Nd mineral ages whole-rock model for garnet-bearing...
