RE:Quartz Pebble Conglomerates - The Big PictureWho knows how many parameters of the quartz-pebble conglomerates of the three realms correlate. Not I. However, two of the realms, Witwatersrand and now India, contain radioactive quartz-pebble conglomerates. What about Pilbara? Are Pilbara's conglomerates radioactive? I haven't seen where that was even tested. This can be done for very little money.
