The Beyşehir–Hoyran–Hadim Nappes crop out over 700 km from NW to SE. Above a regionally autochthonous Tauride carbonate platform the Beyşehir–Hoyran Nappes begin with a thrust sheet (c. 400 m) of mainly redeposited carbonates, quartzose sandstones and mudstones of Mid–Late Triassic age, interpreted as a proximal slope–base-of-slope succession. Above is a thrust sheet (c. 1 km) of Middle–Upper T...

We report compositional, microstructural and seismic properties from 24 samples collected the Middle Allochthon (Seve Nappe) of central Scandinavian Caledonides, its bounding shear zones. The stem both field outcrops continental drilling project COSC-1 include quartzofeldspathic gneisses, hornblende amphibolites, marbles, calc-silicates, quartzites mica schists, medium to high-strain. Seismic v...

Abstract Weirs are used to control and regulate the flow in open channels. In gabion structures, conditions more complex due complexity of through porous body a gabion. The present study aims investigate water surface profile, overflow velocity both through-flow ratios. Six physical models three downstream slopes (V:H 1:1, 1:2, 1:3) two types rockfill (crushed stone rounded gravel) were investi...

Abstract The Ötztal Nappe in the Eastern Alps is a thrust sheet of Variscan metamorphic basement rocks and their Mesozoic sediment cover. It has been argued that main part its southeastern part, Texel Complex, belong to two different Austroalpine nappe systems are separated by major tectonic contact. Different locations have proposed for this boundary. We use microprobe mapping garnet structura...

The Lycian Nappes contain slices of ophiolites and sedimentary rocks various ages that crop out in SW Turkey. They evolved were emplaced under the effect Late Cretaceous-Miocene compressional regime. Tavas Nappe is part contains Jurassic-Eocene sediments. Babadağ Formation, forming middle Nappe, composed limestone at base sized calciturbidites with chert intercalations upper part. Standard Micr...

In this study, experimental procedure and laboratory works have been conducted to investigate the energy loss rate on stepped spillway, using inclined steps together with end sill. To have a more elucidated investigation inclined steps with different slopes (Horizontal , 7, 10, and 12 degrees with respect to the horizon) and end sill with different thicknesses (5 and 10 mm) and heights (6, 8, 1...

The crystal structure of antimonian asbecasite in an ejectum of hypabyssal origin occurring at Tre Croci near Vetralla, Vico volcanic complex, Roman potassic province, Latium, Italy, has been refined to R = 0.042, and is compared to the original crystal structure determination carried out on the Sb-free asbecasite of hydrothermal metamorphic origin from the type-locality, Cherbandung in Binna v...

The studied area, located in the south-western part of Gorce Mountains, is built flysch deposits representing Krynica and Bystrica Subunits Magura Nappe. Here, Late Cretaceous–Early Miocene lithostratigraphic succession Subunit, four formations containing several members were distinguished, whereas only one Middle Eocene–Oligocene formation was identified. Turbacz Kudłoń Thrust Sheets tectonic ...

L'occlusion de la veine centrale de la rétine (OVCR) du sujet jeune est une entité clinique différente de celle du sujet âgé. Elle est moins associée aux facteurs de risque cardiovasculaires et l'étiologie spécifique reste souvent inconnue. L'hyperhomocystéinémie est connue pour être un facteur de risque rare Nous rapportons le cas d'un patient âgé de 25 ans ayant une baisse brutale et indolore...
