Palynological report on South Pacific Pty Ltd (Birkhead) well

An examination of twenty-two samples, chiefly cuttings, from S.P.L. No.1 (Birkhead) well has suggested that the Permian - Triassic boundary lies at a depth between 3600 and 3700 feet below ground level, that a marine influence in Upper Permian times was present and that possibly a somewhat older unit than Upper Permian was present at 5000 feet. No evidence for the age of strata above 1900 feet and below 5035 feet is offered.
