Title

REACTION MINERALS AND RODINGITIZATION REACTIONS IN SABZEVAR OPHIOLITES (SOLEYMANIEH, N-E SABZEVAR)

Pages

Abstract

 Around Soleymanieh village in the NE of Sabzevar, there are a numerous gabbros and microgabbros dykes that have interruped Sabzevar's ophiolites. Most of these dykes turn from black to green, white, yellow and reddish. The surrounding ophiolites have highly altered to serpentine, too.The petrographic studies of discoloured dykes show that, olivine, clino- pyroxenes, orthopyroxenes and calcic plagioclases, (high energy level minerals) have been converted to: wolastonite, prehnite, chlorite, epidote, hydrogrossular, pectolite, and xenotlite (low energy level minerals).Furthermore: XRD, thermic analysis and micropropic studies confirme the mineralization studies and rodingite reactions recognized by polarized microscope. Assemblages minerals and textures show that this complex is a rodingite association. Generally, rodingite mechanism start with serpentinization of olivine and pyroxenes in harzburgites and lherzolites and release of Ca+2 from their structures. These Ca+2 cations can not be accommodated in serpentine crystal structure, therefore, they are concentrated in the fluid associated with serpentinization. Oversaturated fluids of calcium, and with low amount of CO2, under suitable condition, (presence of reactional rocks like gabbros) react with above meantioened rocks and form calcium rich minerals. These fluids will react with basic roch minerals especialy Plagioclasis and creat a host of roddingites minerals (Xenotlite, grossular, Pectolite and others). In Some cases, somme minerals, such as pectolite and xenotlite are replaced in the form of veins within rodingites.
