Summary Palaeomagnetic studies are reported for Precambrian (2590 ± 40 Myr) quartz‐magnetite rocks from three localities of the Karimnagar area, Andhra Pradesh, India. Two localities yielded remanence directions of D = 225° 28′; I =−44° 26′ and D = 225° 31′; I =−41° 28′. The Virtual Geomagnetic Pole positions corresponding to these directions coincide with poles from the charnockites (about 2600 Myr) of Visakhapatnam, Eastern Ghats.
