Below 515 feet the boring passed through the following sequence: a) 515-635 feet - normal marine glauconitic limestones and marls, mostly of presumed Oligocene age; b) 635-1060 feet - paralic carbonaceous sands, silts and clays of Eocene age; c)...

From 270 feet to 515 feet the boring progressed through pale grey bryozoal limestone and marly limestones, with a gradual transition from Batesfordian (Lower Miocene) to probably Longfordian (uppermost Oligocene - Lower Miocene).

Two samples taken from 1405 and 1420 feet respectively, that had been selected at a significant change in lithology, contained no foraminifera, but are considered from their general appearance to be Mesozoic, probably Cretaceous, sediments.

Sludge samples from surface to 270 feet taken at 5-foot intervals have so far been received. Selected typical samples from each formation have been examined microscopically and general faunal lists prepared. Some slight modifications to formation...

Three samples of diamond drill core from 1550, 1570 and 1590 feet depth were examined. All are Cretaceous sediments, the lowest at 1590 feet being a glauconitic shale of marine origin, with Cretaceous foraminifera. This is the first record of marine...
