Abstract

The Stirling Range Formation of Western Australia and the Vindhyan Supergroup of central India have undergone two identical Lower Palaeozoic deformation events. Folding related to dextral reactivation of basement structures suggests a possible continuation of the Indian Narmada-Son-Brahmaputra lineament into SW Western Australia. Subsequent open folding during NE-SW crustal shortening in both terranes is possibly related to Gondwanaland assembly. Whilst the Shillong Group in NE India appears similar to the Stirling Range Formation and Vindhyan Supergroup, further geochronology is required to substantiate a common tectonic history.
