The location of the suture zone between South China Block (SCB) and Indochina (IB) is disputed. Recently, along Song Chay (Chay river) belt, a mélange was proposed as potential SCB IB. However, provenance age poorly known. In order to better constrain elements forming mélange, nine samples detrital material, one orthogneiss were subjected zircon U-Pb Hf isotope analysis. Detrital zircons from s...

Ophiolites, fragments of oceanic lithosphere exposed on land, are typically found as isolated klippen in intensely deformed fold-thrust belts spanning hundreds to thousands kilometers along-strike. Ophiolites whose geochemistry indicates that they formed above subduction zones, may have been relics larger, once-coherent, tracts the leading edge an upper plate below which occurred; such were sub...

-The Fawakhir ophiolitic sequence is composed mainly of serpentinites, metagabbros, boninitic metagabbros and metavolcanics. The serpentinites have geochemical features similar to those of depleted-mantle peridotites. Major and trace element characteristics show that the ophiolitic metagabbro and metavolcanic rocks are of tholeiitic to calc-alkaline affinity. REE abundances in the metagabbros a...

High levels of hexavalent chromium (Cr(VI)) in groundwater are typically attributed to anthropogenic sources. However, scientific reports over the last decade have demonstrated that relatively high levels of Cr(VI) in groundwater may also be due to natural processes. Cr(VI) is among the most significant groundwater contaminants, since it is a potential carcinogenic compound that is commonly fou...

Economic mineral deposits found in oceanic terranes include: mesothermal gold-quartz veins, Cyprus-type massive sulphide, podiform chromite. platinum or cobalt associated with nickel sulphides, as well as asbestos and jade deposits. These are rither hosted by, or otherwise closely associated with oceanic crustal or mantle lithologies. Mesothermal gold-quartz veins and related placers are histor...

In this study, Hallaçlar Volcanites located in Bayramiç-Çanakkale region were evaluated terms of strategic element contents. Mineralogical-petrographical and geochemical investigations carried out on the samples which taken from outcrops with intense hydrothermal alteration. The stratigraphy study area consists Sütüven Formation (Kazdağı Metamorfites), Çetmi Ophiolitic Melange, Evciler Pluton V...

The timing and mechanism of the combination between South China Block (SCB) Indochina (IB) are controversial. Three ophiolitic mélange zones (Ailaoshan, Song Ma, Chay) have been proposed as suture within this collisional orogen. However, relationships among three corresponding tectonic belts unclear. In study, we present detailed structural data for belts. bulk architectures Ailaoshan, Chay cor...

Chemistry of detrital garnets, chrome spinels and tourmalines of 30 selected samples in combination with the general heavy mineral distribution from 523 sandstone samples of the Upper Cretaceous to Eocene Gosau Group of the eastern part of the Eastern Alps and the western West Carpathians result in an advanced picture of sedimentary provenance and palaeogeographic evolution of that area. Garnet...
