Ophiolites are widely studied to unravel how new subduction zones form. They may contain crustal and mantle rocks that formed during juvenile stages of intra-oceanic subduction, modifying the pre-existing oceanic lithosphere within which started, in a magmatic arc upon maturation. Previous geochemical work on Cretaceous Andaman Ophiolite its metamorphic sole, located forearc Sunda zone south-ea...

Fault throw gradients create transverse folding, and this can influence accommodation creation sedimentary routing infill patterns in extensional half-graben basin. The Fanja basin (Oman) offers an excellent outcrop of alluvial fan succession displaying cyclical stacking basin-scale growth-fold patterns. These unique conditions allow for investigation fault-timing development related to fault-t...

Based mainly on field geological observation and geochronologic data, six tectonic units have been recognized in western Inner Mongolia (China), including, from south to north: North China Craton (NCC), Southern Orogenic Belt (SOB), Hunshandake Block (HB), Northern Orogenic Belt (NOB), South Mongolia microcontinent (SMM), and Southern margin of Ergun Block (SME), suggesting that the tectonic fr...

1 REGIONAL GEOLOGY 2 The northern California Coast Ranges are composed the Franciscan Complex, a penetratively 3 sheared set of metasedimentary rocks forming an accretionary prism. The Franciscan complex is 4 subdivided into three broad belts that young to the west: the Eastern, Central and Coastal belts, 5 reflecting the cumulative accretion of oceanic sediments to western North America (McLau...

the subduction of the northern part of the tethys is documented by arc magmatism from upper triassic to lower eocene crosscutting the sanandaj-sirjan zone and from upper eocene to plio-quaternary in the urumieh-dokhtar magmatic zone, situated north of the ssz. neyriz ophiolite is part of middle eatern neo-tethyan ocean of mesozoic that geographically is related to ophiolites of nw-se iran, alon...

I review recent results and unsolved problems concerning the hard-core lattice gas and the q-coloring model (antiferromagnetic Potts model at zero temperature). For each model, I consider its equilibrium properties (uniqueness/nonuniqueness of the infinite-volume Gibbs measure, complex zeros of the partition function) and the dynamics of local and nonlocal Monte Carlo algorithms (ergodicity, ra...

The lava section in the Troodos ophiolite, Cyprus, is chemically stratified and divided into a shallow lava sequence with low TiO2 content and a deeper lava sequence with high TiO2 content. We calculate the viscosity at magmatic temperature based on major element chemistry of lavas in Cyprus Crustal Drilling Project (CCSP) Holes CY-1 and 1A. We find that typical shallow low-Ti lavas have a magm...
