Морфоструктурная эволюция континентально-океанической и внутриконтинентальной шовных зон

Аннотация

Morphostructural evolution of inter-plate - sutural - zones is discussed, island arcs and mountain uplifts being co-pared and likeliness and differences in their evolution being traced for 3 stages i. e. Pre-Late Mesozoic, Late Mesozoic-Early Cenozoic and Late Cenozoic. The two zones developed in similar way at the first stage, difference first appeared at the second stage and considerally deepened at the third. Island arcs evolution proceeds in cycles mostly under oceanic conditions, erogenous uplifts grow continually mostly within limits of the continents. Both kinds of sutural zones are characterized by migration of 'slald arcs replaced by erogenous structures from Eurasian continent towards Pacific and Indian oceans linear block morphostructures to replace microcontinents, mantle and folded arcuate structures to be formed at the places of deep troughs marked by ophiolitic belts.
