Tectonics of the Antarctic<\/strong><\/p>\n

The 1rst edition of Tectonic map of the Antarctic at 1:10 M scale was published by CGMW in 2012<\/p>\n

Significant input of new data during the past decade stimulated upgrading of the 2012 map and preparation of the 2nd edition.<\/p>\n

Design of the legend allows compact visual presentation of both geodynamic and age-related information. Map units are in the first place distinguished by the type of crust they represent, and by formation at plate boundaries or in within-plate settings.<\/p>\n

Oceanic crust is mapped in accordance with the age of generation identified by magnetic anomalies. Archean complexes are grouped in a separate block of the legend believed to represent a primeval continental plutonic\/metamorphic infrastructure (protocrust) lacking clear plate tectonics markers.<\/p>\n

Proterozoic and Phanerozoic complexes are referred to either unstretched or stretched continental terranes.<\/p>\n

Unstretched crust comprises accretionary fold belts (orogens), structural products of their reworking, platform covers and intraplate fold systems.<\/p>\n

Stretched continental crust controls distribution of rift systems and associated sedimentary basins. A greater part of Antarctic continental margin belongs to a magma-rich type. Within lengthy zones contiguous to oceanic crust the continental crust is hyperstretched to the extent of unroofing the upper mantle.<\/p>\n

Generalized view of Antarctic tectonic structures, including their inferred distribution under the ice sheet, is provided in a smaller-scale inset also showing the rates of sea-floor spreading and areas with thickened oceanic crust.<\/p>\n
