The Geology of the Mt. View Range District, Pokolbin, N.S.W.
A.T. Brakel
Abstract. A re-examination of the geology of the Carboniferous Mt. Bright Inlier of the Mt. View Range, near Pokolbin, N.S.W., has led to modification of previous maps and the definition of formal stratigraphic nomenclature for the suite of volcanic and sedimentary rocks exposed therein. This succession consists of the "Kuttung" sequence of the Pokholbin Hills Volcanics and Seaham Formation overlying non-conformably the Lower Carboniferous Mt. View Range Granodiorite. Within the Pokholbin Hills Volcanics, the Mt. Bright Rhyolitic Ignimbrite Member, Flying Fox Gully Trachyandesite Member, Vineyard Lookout Volcanic Agglomerate Member, and Matthews Gaps Dacitic Tuff Member have been named. The Carboniferous rocks are overlain by Permian sediments and basalt, and Triassic sandstones.

Potassium-Argon Dating and Occurrence of Tertiary and Mesozoic Basalts in the Binnaway District
J.A Dulhunty
Abstract. Two Miocene and three Mesozoic K-Ar dates are recorded for basalts occurring in the Castlereagh River Valley. Miocene flows co-extensive with Warrumbungle Mountain basalt flows, indicate a pre-Warrumbungle Castlereagh Valley, similar to, but deeper than, the present valley. Mesozoic Garrawilla lavas, interbedded between Purlawaugh and Napperby sediments extend 16 km south of Binnaway to the southern margin of their area of extrusion, beyond which the Garrawilla horizon has been followed into southern areas where no lavas occur. A tuffaceous mudstone bed associated with late Garrawilla volcanism is described partly as an inter-flow sediment and partly as an open-topped deposit, disconformably overlain by Purlawaugh sediments.

The Stratigraphy of the Bowen Park Group, New South Wales
V Semeniuk
Abstract. The Ordovician Bowen Park Group, 560 m thick, disconformably overlies Cargo Andesite and contains three limestone formations. The lower unit, Dayleford Limestone, contains six members at its type section; in ascending order, they are: Ranch Member, Bourimbla Limestone Member, Manook Limestone Member and Davys Plains Limestone Member. In eastern parts of the Bowen Park area the Oakley Limestone Member is equivalent to the Manooka and Gerybong Limestone Members. The Quandong Limestone, the most fossiliferous formation in the sequence, disconformably overlies the Daylesford Limestone. The Ballingoole Limestone, which conformably overlies Quandong Limestone, contains three members; in ascending order, these are: Cornerstone Limestone Member, Clearview Limestone Member and Downderry Limestone Member. The contact of Bowan Park Group with the overlying Malachi's Hill Beds is redefined and placed at a disconformity.

The Palaeomagnetism of Some Palaeozoic Sediments from Central Australia
B.J.J. Embleton
Abstract. Stable components of magnetic remanence have been isolated (using the partial thermal demagnetization technique) in rock samples collected from the Middle Ordovician Stairway Sandstone and the Siluro?-Devonian Mereenie Sandstone. The stable magnetic remanence is interpreted to be of primary origin. The Stairway Sandstone sampled over about 350 metres, yields a palaeomagnetic south pole situated at 2°S, 50.5°E (α95=8.5°) and the Mereenie Sandstone sampled over the lower 100 metres of a 300 metre succession yields the pole position 41.5°S, 40.5°E (α95=10.5°). The Ordovician pole supports previous results, but the Siluro?-Devonian pole is situated on an older portion of the Australian polar wander curve than would be expected when compared with published Silurian data.

The Measurement Revolution
M.J. Puttock
Presidential Address delivered to the Royal Society of New South Wales at Science House, Gloucester Street, Sydney, 5th April, 1972
Introduction. [1st para.] Two previous Presidents of this society have given an address dealing with measurements and standards of measurement. I venture to speak also on the same topic since it is one which has absorbed my interest and in which I have been engaged for the best part of a lifetime. I choose tonight to comment on some of the significant developments in the field of measurement science which have occurred in recent times.
