Abstract
The Dzabkhan microcontinent was defined by [Mossakovsky et al., 1994] as a cratonic terrane with an early Precambrian basement that combines highgrade metamorphic complexes of the Songino, Dzabkhan, Otgon, Baidarik, Ider and Jargalant Blocks. However, early Precambrian ages have so far only been recognized in the Baidarik and Ider blocks [Kozakov et al., 2007, 2011; Kroner et al., 2015].
Highlights
The Dzabkhan microcontinent was defined by [Mossakovsky et al, 1994] as a cratonic terrane with an early Precambrian basement that combines highgrade metamorphic complexes of the Songino, Dzabkhan, Otgon, Baidarik, Ider and Jargalant Blocks
Moderateand high-Ti basalts of the volcanogenic sequences are comparable to modern N-MORB and E-MORB-OIB oceanic rocks, whereas a differentiated basalt-andesiterhyolite volcanic sequence and associated clastic sediments are interpreted as analogues of modern island arcs and accretionary wedges [Kovach et al, 2013; Yarmolyuk et al, 2015]
The northwestern part of the Dzabkhan block is composed of three zones, which differ in rock associations and their structural-metamorphic evolution [Kozakov et al, 2014]
Summary
The Dzabkhan microcontinent was defined by [Mossakovsky et al, 1994] as a cratonic terrane with an early Precambrian basement that combines highgrade metamorphic complexes of the Songino, Dzabkhan, Otgon, Baidarik, Ider and Jargalant Blocks.
