Recent endogenic regimes of Northern Eurasia

Abstract

The first map of Northern Eurasia is presented showing recent endogenic regimes. It is based on the earthcrust subdivision according to 6 characteristics of its present-day structure and state, those are heat flow, the crust's thickness, relief (elevations), isostatic anomalies, sedimentary mantle thickness and subcrustal layer density. Arguments are advanced in favour of two transition zones from Eurasia to the Atlantic and Pacific oceans, their boundaries being defined. Three superstructures are identified in Northern Eurasia, namely Western transition zone, Central part, and Eastern transition zone, each of them is described in terms of typical set of regimes, their spatial correlation and principal characteristics.
