Reconsidering the ‘phyllocarid’ from the Wade Creek Formation

The fossil record of phyllocarids in Australia is notably limited, with only a few specimens found in Ordovician to Devonian deposits. Therefore, identification of examples from older deposits would inform more aspects of Gondwanan crustacean evolution. Here, a possible phyllocarid reported by Chapman (1925) from the Mount John Shale Member of the Wade Creek Formation is reconsidered. We conclude that the “phyllocarid”-like structure is morphologically comparable to traces ascribed to activity of bivalved arthropods. However, as the Mount John Shale Member is early Neoproterozoic or older, the most parsimonious explanation is that the structure is a cast created by abiotic activity. Re-examination of such specimens represents a useful approach to clarifying previous mis-identifications in the literature and is an important use of historically valuable specimens and collections.

Batten Trough NTGS travs EW, NT, 1989 (P573), radiometric line data, AWAGS levelled

The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium (K), uranium (U) and thorium (Th). The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
 This Batten Trough NTGS travs EW, NT, 1989 (P573), radiometric line data, AWAGS levelled were acquired in 1989 by the NT Government, and consisted of 42860 line-kilometres of data at a line spacing between 250m and 500m, and 100m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places. AUSGeoid98 deflections of the vertical were computed from the geoid-ellipsoid separation surface, while the AUSGeoid93 deflections of the vertical were computed from OSU91A.

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.

Blackstone Combined Bouguer Anomaly geodetic

Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
This Blackstone Combined Bouguer Anomaly geodetic is a complete Bouguer anomaly grid for the Blackstone WA Gravity Survey (P200663). This gravity survey was acquired under the project No. 200663 for the geological survey of WA. The grid has a cell size of 0.00556 degrees (approximately 585m). The data are given in units of um/s^2, also known as 'gravity units', or gu. A total of 309 gravity stations were acquired to produce this grid.

Physical and petrological characteristics of basaltic eruption sites in the Monaro Volcanic Province, southeastern New South Wales, Australia

The Monaro Volcanic Province in southeastern New South Wales is an Early to Middle Tertiary intraplate volcanic province of lava field style, similar to the Newer Volcanic Province of southwestern Victoria. The lava pile is dominated by nepheline basanite, alkali olivine basalt and transitional basalt with minor olivine tholeiite and nepheline hawaiite. Olivine nephelinite lavas occur near the top of the lava pile. The lavas are interbedded with Tertiary sediments and hyaloclastites, some of which have formed in lakes, probably developed by lava damming the pre-basaltic drainage. Thick weathering profiles, in some cases bauxitic, are developed on many of the flows in the lava pile, suggesting long breaks between eruptions at particular sites. This is consistent with sporadic eruplions from widely scattered vents.  Most known eruption sites in the province are represented by volcanic plugs of aphanitic to coarse-grained nepheline basanite, olivine nephelinite, nepheline hawaiite and alkali olivine basalt. Fractionated varieties of these rocks also occur together with minor feldspar-rich and titanian augite-rich cumulates. The predominant plug type is aphanitic to fine-grained nepheline basanite, containing mantle xenoliths and/or kaersutite amphibole.  Basement fractures have had a major influence on the position of volcanic centres. Plugs are concentrated along two northwest trending linear zones: the Bemboka Zone in the north; and the Berridale-Towamba Zone in the south. The Berridale Fault-Towamba Lineament is a major crustal feature of the region.  Other basement structures, including north-northeast-trending faults , appear to have controlled some eruption centres away from the two major zones.

Geology of the Bowen Basin, Queensland

The Bowen Basin is a Permian to Triassic basin extending from Collinsville in the north to Goondiwindi in the south, where it is overlapped by Mesozpic rocks of the Surat Basin (the easternmost extension of the Great Artesian Basin). Beneath the cover the Bowen Basin may be continuous with the Sydney Basin. The northwestern boundary is the pre-Permian Clermont Stable Block, that in the east is formed by the Strathmuir Synclinorium and the Eungella-Cracow Mobile Belt, where pre-Permian rocks are faulted against or overlain by steeply dipping Permian sediments, through which they penetrate as inliers. The western boundary is the Birkhead axis, which separates the Bowen Basin from the Galilee Basin. Between these boundaries lies the structural basin that Derrington (1962) called the Bowen Synclinorium: we prefer the more general term Bowen Basin. Most of the stratigraphy of the basin has been described in detail in published reports, to which reference is made, and descriptive material is therefore kept to a minimum in this Bulletin; only rock units not adequately described elsewhere, or re-interpreted in the light of more recent work, are described here. Figure 1 lists all the main rock units in the order in which they will be discussed. The map area (PI. 1; 1:500,000 geological map) is largely contained within the Fitzroy and Burdekin-Townsville Regions. The physical and cultural geography of these regions is set out in a series of maps and booklets issued by the Commonwealth Department of National Development, which have been freely drawn on for the data that , follow. The towns, culture, and physiographic features of the area are shown in Figure 2. The mapped area is about 150,000 km2 . The coastline extends some 250 km north and south of Mackay. Rockhampton, the largest town in central Queensland, lies 55 km east of the mapped area. The regional survey was a joint project by the Commonwealth Bureau of Mineral Resources and the Geological Survey of Queensland.
