Palaeomagnetic, geochronological and geochemical study of Mesoproterozoic Lakhna Dykes in the Bastar Craton, India: Implications for the Mesoproterozoic supercontinent

Palaeomagnetic analysis of the Lakhna Dykes (Bastar Craton, India) yields a palaeopole at 36.6°N, 132.8°E, dp=12.4°, dm=15.9°, and the U--Pb zircon age obtained from one of the rhyolitic dykes is 1466.4±2.6 Ma (MSWD=0.21, concordia age based on two analyses with identical Pb--U ages), similar to pre...
