Abstract - Summary 
(short description):
For a vertical row of formation of forearc paleozone are typical turbidite-hemipelagic flyschoid complexes with metasomatic horizons volcaninic ash that formed subsynchronousily with volcanism. The main rock-forming mineral metasomatites is the most expressive indicator of geodynamic types paleoarc. So with calc-alkaline volcanic series pricontinental arc associated with the formation of calcium heulandite, with a bimodal spilite-keratophyre series of primitive arc - albite, with highly aluminous volcanism ensimatic arc developed - high-alumina zeolites: laumontite, and analcime.

Keywords:
paleoarc, volcaninic ash metasomatites, indicators, zeolites, P-T conditions.
