О сочетаниях морфоструктур в континентально-океанических шовных зонах (Камчатка, Южная Америка)

Аннотация

Kamchatka belongs to West Pacific type of sutural zones and the Andes - to East Pacific type. Morphostructures of the mountain belts of the Andes and Kamchatka differ in morphostructural compartments and orographic elements dimensions, in the earthcrust thickness, in stages of the tectonic evolution and consequently in the complexity of structures, in the seismic focal zones inclination. Under such a difference there is a general regularity in the morphistructures' combination in common for the Kamchatka and South American parts of the continental-oceanic sutural zone. It can be seen only between the deep-sea trough and volcanic belt (Neogene - Quaternary or recent). The morphostructures resemblance increases with approach to troughs which are zones of subduction. The said differences as well as common features of morphostructures of the areas can be consistently explained in terms of the plate tectonics.
