[1] Log and core data document gas saturations as high as 90% in a coarse-grained turbidite sequence beneath the gas hydrate stability zone (GHSZ) at south Hydrate Ridge, in the Cascadia accretionary complex. The geometry of this gassaturated bed is defined by a strong, negative-polarity reflection in 3D seismic data. Because of the gas buoyancy, gas pressure equals or exceeds the overburden st...

A Cretaceous paleo-accretionary wedge, the Ashin Complex, now exposed along Zagros suture zone in southern Iran, exhibits mafic, metasedimentary and ultramafic lithologies. Field, geochemical petrological observations point to an anomalous high-temperature event that gave rise formation of peritectic (trondhjemitic) melts associated with restitic garnet-bearing amphibolites. Lu-Hf isotopic dati...

Zircon age peaks at 2100–1650 and 1200–1000 Ma correlate with craton collisions in the growth of supercontinents Nuna and Rodinia, respectively, with a time interval between collisions mostly <50 Myr (range 0–250 Myr). Collisional orogens are two types: those with subduction durations <500 Myr and those ≥500 Myr. The latter group comprises orogens with long-lived accretionary stages between Nun...

Introduction: Nowadays,  considerable developments  in  the field  of  radiotherapy have  been  achieved.  They  include  the  advances  made  in  the  equipments  and  treatment  planning  techniques  which  require  highly complex calculations. Such achievements have made it possible to treat cancer patients not only  with  higher  radiation  dose  but  also  with  higher  precision  and  con...

The Central Balkan Zone belongs to the north-vergent fold-and-thrust belt of Alpine orogen. In this zone, pre-Permian low-grade rocks, metamorphosed during Variscan orogeny, were later reworked at two main stages compressional tectonics. Several tectono-stratigraphic subdivisions these metamorphic rocks previously presented, based on a purely stratigraphic approach in absence detailed structura...

The West Burma Terrane (WBT) is a small terrane bounded to the east by Asian Sibumasu Block and west Indo-Burman Ranges (IBR), latter being an exhumed accretionary prism that formed during subduction of Indian oceanic lithosphere beneath Asia. Understanding geological history WBT important for reconstruction closure Tethys ocean India-Asia collision. Currently there are major discrepancies in p...
