the serpentinization of the harzburgitic mantle section of the bou azzer neoproterozoic ophiolite is studied by field mapping, structural observations, optical micrography, sem and x-ray diffractometry, and relationships with co, ni, cr and sulphides minerals are discussed. serpentinization occurred in two major steps with, i) intra-oceanic pseudomorphic serpentinization materialized by the iso...

biogeochemical investigation on s. orientalis, a flora growing on the soils derived from serpentinized dunite in the forumad area, sabzevar ophiolite has been conducted in order to examine the plant-soil relationship in chromite prospecting. due to engagement of cr in the chromite crystal structure and its non-essential role in the plant’s life cycle, ni was used as pathfinder element in biogeo...

few novel cobalt(ii) and copper(ii) complexes [m(fmp)3]cl2, [m(fmp)(bpy)2]cl2,[m(fmp)(phen)2]cl2 and [m(fmp)(phen)(bpy)]cl2 (fmp = 3-furan-2-ylmethylene-pentane-2,4-dione, phen = 1,10-phenanthroline, bpy = 2,2'-bipyridine) have been synthesized andcharacterized by elemental analyses, molar conductance, magnetic susceptibility measurements,ir, electronic, epr, mass spectra and cyclic voltam...
