Palaeomagnetic and magnetomineralogical results are reported from charnockites in basement terrane at the eastern sector of the WSW–ENE granulite belt of South India. Magnetite is the dominant ferromagnet identified by rock magnetic and optical stu

This study has investigated palaeomagnetism and magnetic properties of a tract of continental basement in south India metamorphosed to granulite facies close to the Archaean–Proterozoic boundary (∼2600 Ma) at former depths of 20–35 km. The meta

The Banded Hematite Jasper Formation within the Iron Ore Supergroup of the Singhbhum Craton in eastern India comprises fine alternating layers of jasper and specularite. It was deposited at ∼3000 Ma and deformed by a mobile episode at ∼2700 Ma. H

A new palaeomagnetic study of mid Cretaceous lavas from 23 localities in the northern part of the Rajmahal Hills gives a mean virtual geomagnetic pole at 10.4°N, 296.6°E, confirming the results of earlier workers. Stepwise thermal and alternating f

SUMMARY To evaluate suggestions from earlier work that a reversal of magnetization is present in the Rajmahal Traps of mid-Cretaceous (probable Aptian) age in north-eastern India, we have sampled a 140 m thick section comprising a minimum of nine flo

The Precambrian Banded Haematite Jasper rocks of Orissa show red and dark coloured rhythmic bands. The former are made up of cryptocrystalline silica and haematite pigment ( 10 μm). X-ray diffraction studies also seem to indicate that haematite is t
