The Mount Charlotte gold deposit comprises a series of steeply plunging, vein stockwork orebodies that are surrounded by three concentric and mineralogically distinct alteration haloes. Fluid inclusions from quartz veins within each alteration zone have been analyzed and compared to determine possible temperature and chemical trends. Fluid inclusions associated with Type I alteration are mostly 3 phase, aqueous inclusions containing liquid + vapor CO2. These inclusions homogenize from 98 to 304?C with a mode at 235?C. Inclusions in Type II alteration are generally two-phase, liquid- or vapor-rich fluid inclusions and they homogenize at temperatures around 270?C. Type III alteration contains two distinct types of fluid inclusions. The most abundant population consists of coexisting liquid- and vapor-rich, two-phase aqueous inclusions which homogenize around 312?C. The second and rarer fluid inclusion population consists of methane-rich inclusions containing approximately 5 vol.% vapor and these homogenize around 264?C. This indicates that there is a general decrease in the temperature of the fluids from Type III alteration to Type I alteration with an average variation of 65?C across the orebody. The CH4 content of the fluids, as determined by laser Raman microprobe analyses of fluid inclusions, decreases from Type III alteration to Type I alteration. The fluids associated with Type I alteration contain little or no CH4, whereas, the fluids associated with Type II and Type III alteration contain considerable quantities of CH4 with some Type III inclusions containing only methane and water. These lateral and vertical zonation patterns indicate that mineralization at Mount Charlotte was accompanied by cooling and oxidation of the ore-bearing fluid as it reacted with the host rocks. Gold precipitation occurred by a combination of desulphidation and oxidation of an initially reduced, ore-bearing fluid. Phase separation during tectonic activity may have also led to the precipitation of minor amounts of free gold within the quartz veins and along vein margins.

A suite of 18 oils from the Barrow Island oilfield and a reference oil from Saladin-11 (Carnarvon Basin, Australia) have been analysed compositionally in order to determine the detailed effect of minor to moderate biodegradation on C5 to C9 hydrocarbons. Carbon isotopic data for individual low molecular weight hydrocarbons was also obtained for 6 of the oils. The Barrow Island oils came from different production wells, reservoir horizons, and compartments, but have a common source (the Upper Jurassic Dingo Claystone Formation). Ratios based on hopanes, steranes, alkylnaphthalenes and alkylphenanthrenes indicate thermal maturities of about 0.8% Rc for most of the oils. The co-occurrence in all the oils of relatively high amounts of 25-norhopanes with C5 to C9 hydrocarbons, aromatic hydrocarbons and cyclic alkanes implies that the oils are the result of multiple charging, with a heavily biodegraded charge being overprinted by fresher and more pristine oil. The later oil charge was itself variably biodegraded, leading to significant compositional variations across the oilfield which help delineate compartmentalisation. Biodegradation resulted in strong depletion of n-alkanes (>95%) from most of the oils. Benzene and toluene were partially or completely removed from the Barrow Island oils by water washing. However, hydrocarbons with lower water solubility were either not affected by water washing, or water washing had only a minor effect. etc etc (not enough space for all the Abstract)

This map is part of the series that covers the whole of Australia at a scale of 1:250 000 (1cm on a map represents 2.5 km on the ground) and comprises 513 maps. This is the largest scale at which published topographic maps cover the entire continent. Each standard map covers an area of 1.5 degrees longitude by 1 degree latitude or about 150 kilometres from east to west and 110 kilometres from north to south. There are about 50 special maps in the series and these maps cover a non-standard area. Typically, where a map produced on standard sheet lines is largely ocean it is combined with its landward neighbour. These maps contain natural and constructed features including road and rail infrastructure, vegetation, hydrography, contours (interval 50m), localities and some administrative boundaries. The topographic map and data index shows coverage of the sheets. Product Specifications Coverage: The series covers the whole of Australia with 513 maps. Currency: Ranges from 1995 to 2009. 95% of maps have a reliability date of 1994 or later. Coordinates: Geographical and either AMG or MGA (post-1993) Datum: AGD66, GDA94, AHD. Projection: Universal Traverse Mercator (UTM) Medium: Paper, flat and folded copies.
