METASOMATIZM

METASOMATIZM, metasomatoz (az meta… va somatos — jism), yak namudi metamorfizm; az tasiri magma va mahlulho tagyir yoftani tarkibi khimiyavi va mineralii jinshoi kuhi. Haggomi Metasomatizm az joy ivaz kardani moddaho (baynn mahlulu jinshoi kuhi) hajm va strukturai jinshoi kuhi tagyr nameyoband. Prosessi Metasomatizm dar du marhala meguzarad: magmavi va postmagmavi. Dar marhalai Metasomatizmi magmavi az tasiri magmai dar qishri Zamin joygnrshuda jinshoi atrofi on granitizasiya meshavand, yane ba granit tabdil meyoband. Dar marhalai Metasomatizmi postmagmavi (badi magmavi) az magmai khunukshuda istoda mahlulhoi gidrotermali va gazmonand judo shuda, ba bolo harakat mekunand va az tasiri onho dar jinshoi kuhi hodisahoi skarnshavi, greyzenizasiya, mikroklinizasiya, berezitizasiya, albitizasiya, kvarsdorshavii jinsho va g. ruy medihand. Az jihati intiqoli modda Metasomatizm diffuzioni va infiltrasioni meshavad. Dar Metasomatizmi diffuzioni joyivazkunii moddaho hangomi ba jinshoi kuhi zanida guzashtani mahlulhoi nisbatan sustjarayon ruy medikhad. Dar Metasomatizmi infiltrasioni moddaho dar natijai az magzi jinshoi kuhi guzashtani jarayoni mahlulhojchoy ivaz mekunand. Metasomatizm boisi hosilshavii konhoi metasomatii gunogun megardad.

Dar muayyan kardani asoshoi nazariyavi va tasnifi genetikii Metasomatizm khizmati akad. AF SSSR D. S. Korjiiskiy khele kalon ast.
