La Trobe University Department of Geology Bundoora / Victoria / Australia 3083 Telephone 478 3122 14th April, 1976. Dr. B. Mason, Department of Mineral Sciences, National Museum of Natural History, Smithsonian Institution, [[underline]] WASHINGTON [[/underline]], D.C. 20560. Dear Brian, Bill Compston and I have started a Rb-Sr dating project on enstatite achondrites at the A.N.U. by redetermining Bishopville. I would be very grateful if you could provide us with a sample of Pena Blanca Spring for dating or suggest a source. Pena Blanca Spring would give a better base for interpreting the complicated Bishopville data and allow a further comparison with I-Xe results. We require an absolutely clean 5 g chip for mineral separation and this would be best achieved if you could supply an 8 to 10 g fragment freshly broken from an interior surface. Contamination is the bugbear as usual, so that a broken fragment is superior to a sawn one. Given the 10 g chip we would then strip it to 5 g in the clean room at A.N.U. Yours sincerely, Chris Gray [[underline]]Chris Gray[[/underline]]
