Quartz Pebble Conglomerates - The Big PictureAs Rhino10 pointed out, The Pilbara and India were once joined.....There is an interesting summary of the Pilbara, newly published by Klondike Strike Inc., entitled "Pilbara Playbook". Figure 3 is of particular interest, for it shows a plate tectonic reconstruction that links The Witwatersrand, India, and The Pilbara; just google "Pilbara Playbook", to get to it.
