Indian apparent polar wander path (APWP) for Phanerozoic and post-late Palaeozoic. This APWP is compiled on basis of data available at October 1981 from peninsular and extrapeninsular Indo-Pakistan and from DSDP cores from the Indian Plate. One of the more important and newly recognized features of this APWP is a large-scale Triassic-Jurassic loop. This loop indicates a changeover from a late Palaeozoic-early Mesozoic northwards and counter-clockwise rotational movement, with Greater India reaching moderately low southern latitudes, into a southwards and clockwise rotational movement during the Early to Middle Jurassic. Studies of extrapeninsular regions up to and north of the Indus-Tsangpo suture zone have shown wide-spread presence of magnetic overprints, which delineate two regionally confined age groups. Younger overprints (20-40 m.y.) predominate in the more external thrust zones. Older overprints (50-60 m.y.), in contrast, are found in the more internal zones both north and south of the Indus-Tsangpo suture zone. The latter are interpreted to reflect a late phase of relaxation in the early Tertiary collision of Greater India with south-central Asia.--Modified journal abstract.
