The behavior of fluids at the subduction plate interface and their chemical rheological impacts remain poorly constrained. Based on detailed fieldwork, petrographic geochemical analyses thermobarometry, present study documents an example a block-in-matrix ‘mélange’ metasomatized along (Kampos-Lia mélange zone, Cycladic Blueschists, Syros island). We show that this particular zone is preserved f...

Abstract Ophiolitic mélanges in Anatolia represent Mesozoic subduction-accretion complexes, which are unusually poor land-derived coarse-clastic rocks. A segment of the ophiolitic mélange Beynam region south Ankara was studied. The consists three accretionary units (AUs), distinguished by lithology, structure, age and geochemistry. At base there is a serpentinite mélange, overlain semi-intact U...

This note deals with localized approximations of homogenized coefficients of second order divergence form elliptic operators with random statistically homogeneous coefficients, by means of “periodization” and other “cut-off” procedures. For instance in the case of periodic approximation, we consider a cubic sample [0, ρ]d of the random medium, extend it periodically in R d and use the effective...
