Potential Antitumour Activity of Some Amino Acid Metal Systems
Alexander J. Charlson, Kevin E. Trainor, and Edward C. Watton
Abstract. Copper (II) chelates of L-asparagine and L-glutamine have been prepared. Bis(L-glutaminato)copper(II) shows significant anticancer activity in the KB cell culture test-system, but bis (L-asparaginato)copper(II) is inactive in the same test-system. Induction of filamentous growth in Escherichia coli is being used as a preliminary screen for antitumour activity of coplex species which cannot be isolated from solution. Using a continuous variation method it is shown that mixtures of L-glutamine and copper(II)sulphate in a molar ratio of 1:1 L-glutamine and potassium platinum(II)chloride in a molar ratio of 3:2 and L-aspargine and potassium platinum(II)chloride in a molar ratio of 1:1 induce filamentous growth in E. coli.

Bedrock Topography in Northern Jervis Bay
B.D. Johnson and A.D. Albani
Abstract. A detailed seismic investigation of the northern part of Jervis Bay, has confirmed the existence of a watershed between Flora Point and Green Point. Additional details have also been obtained on the dendritic drainage pattern.

Structure and Jointing in Permian Rocks Near Ravensworth, N.S.W., Northern Sydney Basin.
David E. Gray
Abstract. Permian rocks near Ravensworth, New South Wales are part of the northern margin of the Permo-Triassic Sydney Basin. Major structures in the area are open, sub-horizontal, northwest trending, non-cylindrical folds. The Bayswater and Glennies Creek Synclines and the Camberwell Anticline are the largest of these structures. The folds are second phase en echelon "pod" folds developed on the eastern flank of the Muswellbrook Anticline.
The main faults near Ravensworth are the Hunter Thrust and the Hebden Fault. The Hunter Thrust is a major border thrust along the northern margin of the Basin which separates Permian and Carboniferous strata. The Hebden Fault is a high angle reverse fault which closes against the Hunter Thrust forming a fault wedge of faulted Permian strata.
Four major systematic joint sets (north-northeast, north-west, north-south and east-west) occur in the rocks and appear to have developed independent of folding and faulting. Modifications of joints in strata adjacent to the Hunter Thrust has taken place because of movements along the Thrust after joint formation.
The deformation history of Permian rocks along the northern margin of the Sydney Basin involves two periods of folding, a protracted period of thrusting and a phase of jointing.

The Geology of the Windellama Area, New South Wales
Ruth Mawson
Abstract. Mapping of some 50 km2 in the Windellama area has revealed a sequence of 1,700 m or more of Early Devonian carbonate and terrigenous sediments downfaulted into rocks at least in part of Late Silurian age. The Devonian succession consists of approximately 200 m of terrigenous sediments overlain by about 283 m of carbonates, the Windellama Limestone, overlain in turn by a further 1,200 m or more of sandstones and siltstones. The Windellama Limestone yielded rich macro and micro-faunas of Early Devonian (Lochkovian) age. The overlying terrigenous sediments have yielded a coral-trilobite-brachiopod fauna of Early Devonian (Praguian) age.

The Merrimbula Group of the Eden-Merrimbula Area, N.S.W.
J. Steiner
Abstract. The Upper Devonian Merrimbula Group is divided into three formations and represents a coarse red-bed succession which contains a finer-grained, drab sequence in the middle. The basal 90 m red-beds are termed the Twofold Bay Formation. The middle drab sequence and the upper red-beds are defined as the 350 m Bellbird Creek and 430 m Worange Point Formation respectively. The Twofold Bay Formation records the deposits of a northerly sloping alluvial fan which was built up by a braided stream system and grade into the deposits of a small meandering stream at the top. The lowest Bellbird Creek Formation represents a marine transgression consisting of barrier island, littoral and shallow marine facies which are overlain by subaqueous deltaic deposits. During Bellbird Creek time the palaeoslope dipped toward the southeast with a southwest-northeast shoreline trend. The upper Bellbird Creek Formation consists of tidal flat deposits with some windblown dunes and lagoon deposits at the top. Average palaeotidal range may have been of the order of 4.8 m. During Merimbula time palaeowind direction was toward the north. The Worange Point Formation records the deposits of a coastal plain, meandering river belt with the palaeoslope dipping gently toward the south-east. The basal Worange Point rocks probably represent subaerial, top-set deltaic beds. The Worange Point meander belt may have had a width of 2.6 km and the channel depth may have been characterized by a normal low water stage of 17 m. Clay mineralogy possibly indicates a paleoclimatic warming-up trend during Merrimbula time.

Local Compactness and Free Products of Topological Groups
Sidney A. Morris
Abstract. It is proved here that a free product (free abelian product) of an infinite family of non-totally disconnected topological groups is never locally compact.

Lower Silurian Rugose Corals from Central New South Wales
R.A. McLean
Abstract. Six species of rugose corals (four new) are described from beds of Upper Llandovery age in central N.S.W. Representative of the family Arachnophyllidae Dybowski are Arachnophyllum epistomoides Etheridge 1909 (Rosyth and Quarry Creek Limestones), Ptychophyllum auctum sp. nov. (Rosyth and Quarry Creek Limestones), P. cf. sibiricum Ivanovskiy (Upper limestone horizon, Cobblers Creek, Angullong district), Cyathactis variabilis sp. nov. (Rosyth Limestone) and Stereooxyloides multicarinatus sp. nov. (Rosyth Limestone). Strombodes rosythensis sp. nov. (Rosyth Limestone) has uncertain suprageneric affinities.

A Note on the Fossiliferous megafloras of the Nymboida and Red Cliff Coal Measures, southern Clarence-Morton Basin, N.S.W.
J.C.E. Flint and R.E. Gould
Abstract. The Nymboida and Red Cliff Coal Measures, southern Clarence-Morton Basin, N.S.W. have yielded Triassic Dicroidium megafloras. The Nymboida flora comprises at least 26 species and is correlated with the Middle Triassic flora of the Eske and Neara Beds of Queensland. The Red Cliff Flora comprises 15 species and is equated with the Queensland Upper Triassic Ipswich flora.

Late Ordovician Coral Fauna from North-Eastern New South Wales
Russell L. Hall
Abstract. The first Ordovician coral faunas described from north-eastern New south Wales occur in two widely separated fault blocks in the Peel Fault system: the Trelawney Beds south-east of Tamworth and the Uralba Beds north of Attunga. The latter is a new stratigraphic unit. The faunas are rich in heliolitids, halysitids, favositids and members of the early rugose genera Palaeophyllum, Cyathophylloides and Crenulites. New taxa described are the rugose corals Palaeophyllym bothroides sp. nov., P. trelawnyense sp. nov., Cyathophylloides sinuata sp. nov., C. juncta sp. nov., Crenulites australis sp. nov., C. australis minor sp. et subsp. nov. and the tabulate corals Plasmoporella baciliformis sp. nov., P. crassus sp. nov., P. spinimarginatus sp. nov., P. rarispinulatus sp. nov. Catenispora flexa sp. nov., C. spatiosa sp. nov. and Falcicatenispora stricta sp. nov. These faunas are of Estonian or early Bolindian age and are tentatively correlated with Fauna IV of Webby (1972) in the Ordovician sequences of central western New South Wales.
