The Cambrian¿Ordovician Wagonga Group contains basalts at Melville Point and Barlings Beach, 20¿km south of Batemans Bay, New South Wales. At Melville Point, the succession has basal altered basalts overlain by chert and interbedded siliceous mudstone of the Wagonga Group, in turn overlain by turbidites and chert of the Adaminaby Group with a latest Cambrian to earliest Ordovician age. By contrast, at Barlings Beach, basalt is associated with highly disrupted chert (tectonic mélange), various slivers of mudstone and turbidites, and turbidites of the Adaminaby Group. Immobile elements in the basalts show consistent patterns that allow the magmatic affinity and tectonic setting to be determined in spite of pervasive hydrothermal alteration and subsequent lower greenschist facies metamorphism that accompanied strong folding and multiple foliation development. The Melville Point basalts show Ti/V ratios transitional between arc and MORB and therefore may have formed in either a forearc or backarc basin setting. However, these rocks have higher Ti/V ratios, LREE, Th and Nb than found in forearc basalts and are therefore considered to have formed in a backarc basin setting. In contrast to Melville Point, most basalts at Barlings Beach have a geochemical signature distinctive of ocean island settings like those reported from elsewhere in the Wagonga Group. We believe these rocks developed in a Cambrian backarc basin setting. In the Early to Middle Ordovician, much of the ocean basin was inundated by quartzose turbidites followed by basin destruction with accretion/underplating at a Late Ordovician¿early Silurian Benambran subduction zone and formation of the Narooma Accretionary Complex.

2014Och DJ, Offler R, Zwingmann H, 'Constraining timing of brittle deformation and fault gouge formation in the Sydney Basin', Australian Journal of Earth Sciences, 61 337-350 (2014) [C1]

Structural and K-Ar dating studies of gouge in N-S, NNE and E-W-trending faults in four locations in the Sydney-Hunter region are reported. The fault zones are manifest as joint swarms and highly brecciated zones containing gouge with authigenic illite produced as a result of fluid infiltration. Strike-slip movement accompanied by minor dip-slip, normal movement occurred on the NNE faults, with dip slip on N-S and E-W-trending faults. In this study, gouge from a NE-trending, steep, SE-dipping fault showing dip-slip movement at Cut 10, on the Hunter Expressway and from an E-W-trending, steep south-dipping, normal fault at the Westside Open Cut, Lake Macquarie have been analysed. K-Ar dating of illite and illite-smectite in fractions extracted from fault gouges in areas unaffected by a thermal overprint reveals ages varying from 166 to 119 Ma for the <2 µm and finer fractions, and a mean age of ca 120 Ma for the <0.4 µm fraction. In the Sydney area and the Westside Open Cut coal mine, Lake Macquarie, the ages obtained from similar size fractions both for the gouge and for the host rocks are younger (134-76 Ma; av. <0.4 µm = 111 Ma). The data indicate influence of a thermal overprint associated with subsurface magmas emplaced during the early stages of the rifting of eastern Gondwana during the early Cretaceous. © 2014 © 2014 Geological Society of Australia.

In the Southern New England Fold Belt, N.S.W., Australia, bo studies of K-white micas have shown that the Tamworth Belt and Tablelands Complex contain sequences with distinctive metamorphic imprints. The white micas in the forearc basin sediments of the Tamworth Belt record low pressure conditions, whilst those in the accretionary complex sequences of the Tablelands Complex show an intermediate pressure character. The results are in accord with the plate tectonic models proposed for the Southern New England Fold Belt. Illite crystallinity analyses have revealed that rocks of diagenetic to lower anchimetamorphic grade are developed in the forearc succession and diagenetic to epimetamorphic grade in the accretionary complex, with grade increasing progressively from south to north. They also indicate that the Peel Fault System is not a major zone of thrusting. -Authors

For 80 slates and phyllites of late Silurian-early Carboniferous age in this area in the NE portion of the Lachlan fold belt, W of Sydney, illite crystallinity values vary from 0.40 DELTA o 2theta (CuKalpha ) on the Molong anticlinorium to 0.12 DELTA o 2theta within the axis of the synclinorium, suggesting anchizonal to epizonal metamorphic conditions. This is in agreement with previous observations of a change from prehnite-pumpellyite facies (in the anticlinoria adjacent to the synclinorium) to middle greenschist facies in the axis (M.A. 69-2599). The mean b value from the pelitic rocks is 9.017 A, in close agreement with that for the adjacent Capertree anticlinorium. Statistical tests indicate two b populations in the Hill End synclinorium (9.010 and 9.022 A) with the lower values concentrated in the S portion of the structure; the higher geothermal gradient indicated by the lower b values is attributed to the presence of granitic intrusions at shallower depths than elsewhere in the synclinorium.-R.A.H.

The stratiform and vein-type pyritic Ag-Pb-Zn-Cu sulphide deposits of Sunny Corner, NSW, are hosted by acid volcanic and clastic sedimentary rocks of Middle Silurian to early Devonian age. The rocks have been subjected to low-grade regional metamorphism (prehnite-pumpellyite facies) and three phases of folding and four faulting events are recognized. Pyrite is intensely fractured, indicating brittle deformation. Chalcopyrite and galena exhibit deformation twins and slip planes indicating ductile deformation; sphalerite and chalcopyrite show straight and curved grain boundaries and dihedral angles of 120o as evidence of annealing recrystallization. Sulphur isotope ratios for 22 samples from five deposits range from 1.7 to 10.7per mille and average 7.4per mille. Sulphur isotope data are similar to those from other stratiform sulphide deposits in acid volcanic rocks of late Silurian age in the E Lachlan Fold Belt, especially Woodlawn and Captains Flat, and together with other features of the mineralization, suggest a volcanic exhalative origin for the Sunny Corner deposits.-H.K.H.

Sub-greenschist-facies metamorphism has produced unusual Fe-rich, actinolitic amphiboles in metadolerites in this area approx 300 km N of Sydney. Microprobe analyses show edenite, riebeckite, ferritschermakite and Ti-tschermakite coupled substitutions. Their high Fe content is attributed to high aFe2+ and aFe3+ in the fluid phase produced during the breakdown of clinopyroxene, hornblende, magnetite and ilmenite; the high aFe2+ led to Fe2+ occupying the B site, resulting in production of sub-calcic amphiboles.-R.A.H.
