Precambrian-Cambrian ultramafic-mafic magmatism in Mongolia and southern Siberia
Abstract
Trends of Precambrian-Cambrian lithosphere development (particularly the formation of an ocean-type crust) in the Central-Asian folded zone are examined. Three types of ultramafic-mafic (UM-M) associations in folded regions reflecting lithospheric evolution features are found to have a global character: UM-M associations of archean granulite zones (type I), greenstone zones (type II), and large laminated plutons (type III).
