The Manamedu Complex: Geochemical constraints on Neoproterozoic suprasubduction zone ophiolite formation within the Gondwana suture in southern India

“…The PCSZ in southern India has been recently interpreted as the zone of closure of the Neoproterozoic Mozambique Ocean (Collins et al, 2006(Collins et al, , 2007Santosh et al, 2009a). The supercontinent Rodinia assembled in the Mesoproterozoic (∼1300 Ma, McMenamin and McMenamin, 1990) and broke up during the Neoproterozoic at ∼800 Ma (see Santosh et al, 2009b for a recent review). The Mozambique Ocean formed during the breakup of Rodinia (although some authors represent its coexistence with Rodinia as one of its flanking marginal oceans) and closed with the assembly of the Gondwana supercontinent at ∼550 Ma.…”

Dyke swarms as indicators of major extensional events in the 1.9–1.2Ga Columbia supercontinent

“…The three dyke swarms identified here which were intruded in the final stages of the break-up of Columbia (Hou et al, 2008b) and early plate reorganisation to form Rodinia (McMenamin and McMenamin, 1990) between ca. 1300 Ma and 900 Ma are discussed below.…”

LA ICP MS U–Pb ages of detrital zircons from Russia largest rivers: Implications for major granitoid events in Eurasia and global episodes of supercontinent formation

“…The Rodinia supercontinent is thought to be assembled during a time interval from 1.3 Ga to 0.9 Ga and to include almost all the continents of the world (e.g., McMenamin and McMenamin, 1990;Condie, 2001;Maruyama et al, 2007;Li et al, 2008). The Grenvillian orogeny (ca.…”
