New Query

Information
has glosseng: The Dharwar craton in South India presents a natural cross-section of late-Archaean continental crust. There are three main structural zones: a root zone of highly heterogeneous petrology (from monzonite to granite) and texture (phenocryst accumulation), a "channel zone" where evidences of large scale magma ascent can be observed, and a zone of superficial intrusions, consisting in independent homogeneous intrusive bodies. In the root zone, mantle-derived magma underwent fractional crystallisation which was followed by mingling between the residual liquids and melts generated by anatexis of the surrounding gneissic basement.
