First record of shared species of Late Permian small foraminiferids in Australia and Russia: time correlations and plate reconstructions

At least 12 species of small calcareous foraminiferids known from early Late Permian assemblages from Arctic Russia and adjacent areas also occur in assemblages from the eastern Australian Ingelara Formation of the Bowen Basin (Queensland).  A key species is Pseudonodosaria borealis (Gerke 1952), newly recognised in Australia. The shared species allow direct correlation with Late Permian Russian assemblages of Kazanian age. This is the first microfaunal evidence of correlative strata in Gondwana; previous chronologic ties in this region have relied on rare and geographically scattered records of ammonoids from both eastern and western Australia. Other shared foraminiferids from the Ingelara Formation include taxa described in 1914 by Tscherdynzev [Nodosaria krotovi, N. noinskii and N. netchajevi, Lenticulina (Astacolus) rotaliaeformis]; and by Gerke in 1952 and 1961 [Frondicularia inflata, F. bella, F. prima, F. tijanica, F. dilemma, Tristix permiana, Nodosaria cuspidulata). A brief synonymy shows that almost all of these Russian taxa may have been recognised previously in Australian assemblages, but under different names. Pseudonodosaria serocoldensis (Crespin 1945) is considered an ancestor of P. borealis and its appearance in older assemblages in both Spitsbergen (Kungurian) and Australia (Bowen Basin, late Artinskian) suggests that similar evolutionary developments of the faunas occurred throughout a continuous seaway that connected these areas since the early Permian.  Migration of these benthic forms is presumed to have occurred via deep ocean currents and suggests that either Arctic Russia (Nordvik Basin, Siberia: parts of Novaya Zemlya) and Spitsbergen were in closer proximity to Australia than is generally accepted in modern plate reconstructions for the Late Permian or, most likely, that new oceanic dispersal patterns are required to explain their distribution.

GSQ Cooper Basin magnetic grid geodetic

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data 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 GSQ Cooper Basin magnetic grid geodetic has a cell size of 0.00083 degrees (approximately 88m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 2008 by the QLD Government, and consisted of 168416 line-kilometres of data at 400m line spacing and 60m terrain clearance.

Post-drill analysis to assess the prospectivity and geological risks for energy resources in the Pedirka, Simpson and western Eromanga basins

The Permian Pedirka, the Triassic Simpson and the Jurassic–Cretaceous western Eromanga basins in central Australia have undergone a sporadic exploration history which commenced in the 1950s. Exploration initially focused on conventional hydrocarbons from the 1950s–1980s, before shifting towards coal seam gas (CSG) opportunities in the 2000s. The basins remain underexplored with only 42 wells drilled, and ~16,000 line&nbsp;km of 2D seismic acquired across a study area of ~210,000&nbsp;km2. An active petroleum system has been proven by a non-commercial oil discovery at Poolowanna&nbsp;1, as well as by several wells that show evidence of residual oil columns. However, sparse and low-quality seismic data make it challenging to map and identify new energy resource opportunities.

Geoscience Australia, the Northern Territory Geological Survey, and the South Australian Department for Energy and Mining are collaborating on the Australia’s Future Energy Resources (AFER) project to undertake an assessment of the resource potential for conventional and unconventional hydrocarbons and the carbon capture and storage (CCS) potential in the Pedirka, Simpson and western Eromanga basins. The project’s objective is to produce spatially-enabled and risked resource estimates to provide government and industry stakeholders with decision making tools to address the region’s energy resources and CCS potential.

Post-drill analysis is a key component of evaluating the resource potential of a region by ensuring that a systematic, data-driven approach is used to evaluate discrete exploration play intervals and trapping mechanisms. The study area has been divided into 16 chronostratigraphic play intervals and post-drill analysis has been undertaken to evaluate the presence and effectiveness of the main conventional petroleum systems play elements of reservoir, seal, trap and hydrocarbon charge. The post-drill analysis methodology to assess conventional hydrocarbons has also been modified to assess the geological elements that are essential to evaluate unconventional petroleum resources and CCS potential within the study area. The qualitative results indicate conventional hydrocarbon, CCS, CSG and shale hydrocarbon opportunities across multiple plays, highlighting that an area that has been primarily explored for one resource type in the past may have other opportunities for industry to evaluate.

This Abstract was submitted/presented to the 2022 Central Australian Basins Symposium IV (CABS) 29-30 August (https://agentur.eventsair.com/cabsiv/)

Petrography of samples from Waukarlycarly-1: Report for Geoscience Australia

This report presents the results of scanning electron microscopy (SEM) analyses on 2 core samples from the GSWA Waukarlycarly 1 stratigraphic well drilled in the Canning Basin. The well was drilled as part of a co-funded collaboration between Geoscience Australia (GA) and the Geological Survey of Western Australia (GSWA) aimed at gathering new subsurface data on the potential mineral, energy and groundwater resources in the southern Canning Basin. The
collaboration resulted in the acquisition of the Kidson Deep Crustal Seismic Reflection Survey in 2018; and the drilling of deep stratigraphic well GSWA Waukarlycarly 1, located along the Kidson
Sub-basin seismic line within the Waukarlycarly Embayment in 2019 (Figure 1).
GSWA Waukarlycarly 1 reached a total depth of 2680.53 m at the end of November 2019 and was continuously cored through the entire Canning Basin stratigraphy. Coring was complemented by the acquisition of a standard suite of wireline logs and a vertical seismic profile. The work presented in this report constitutes part of the post well data acquisition. The purpose of the SEM analysis was to determine mineralogy and textural relationships between grains, verify the presence of organic material at the micro-scale, document i) the presence of diagenetic alterations to the detrital mineral assemblage and ii) eventual distribution of visible pores.

Middle Cambrian agnostids : systematics and biostratigraphy

This Bulletin presents the taxonomy, temporal stratigraphy, palaeogeography, and ecology of the Middle Cambrian agnostid trilobites beginning with their arrival in the
 Templetonian and reaching an acme of diversification in Undillan time; agnostids of the latest Middle Cambrian were described earlier (bpik, 1961b, 1967). The material described now contains numerous complete specimens which supplied information regarding the morphology and function of the agnostid skeletons so far not attainable with certainty from disjointed sclerites. The nine named and one unnamed (the initial Templetonian) zones are integrated into four geographically named stages, completing the scale of stages by starting with the Ordian and leading into the early Upper Cambrian the. continuous sequence of stages reads; Ordlan, Templetonian, Floran, Undillan, Boomerangian; followed by the early Upper Cambrian Mindyallan and Idamean. The scale of the zones of the agnostid species is the pivot of the biostratigraphic documentation; it is the time scale A. H. Westergaard introduced in 1946 in Sweden. I have implemented this scale in Australia in the field and in unpublished and published reports for over two decades, but 'on parole', in advance of the descriptions and illustrations of the relevant fossils which are presented here.

Canning Basin Biozonation and Stratigraphy Chart No. 2

Biostratigraphy is the branch of stratigraphy that uses fossils to establish relative ages of rock and correlate successions of sedimentary rocks within and between depositional basins. A biozone is an interval of geologic strata characterised by certain fossil taxa. Such intervals are often defined by the first appearances (range bases), apparent extinctions (range tops/last appearances), or abundances of fossil index species. These key index species should be relatively abundant, short-lived taxa that are easy to recognise and as geographically widespread as possible. Widely used fossil groups include brachiopods, conodonts, dinoflagellate cysts, foraminifera, graptolites, nannofossil, spores and pollen and trilobites. Zonal schemes based on several different fossil groups can be used in parallel, and the zones can be calibrated to the absolute geological timescale using tie points to rocks which have been radio-isotopically dated.

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 uranium (K), uranium (U) and uranium (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 GSV Yea VIMP Vic pot tho ura totg 4band radiometric grid geodetic has a cell size of 0.0005 degrees (approximately 50m). The data used to produce this grid was acquired in 1997 by the VIC Government, and consisted of 14605 line-kilometres of data at 200m line spacing and 80m terrain clearance. The grid was produced by applying the colours red to the Potassium ground concentration, green to the Thorium concentration and blue to the Uranium concentration. The colours were clipped to a 99% linear scale. These colours were transparent over a shaded Total Count. This clipping will necessarily introduce some artefacts into the ratio grids in areas of very low radioelement concentrations. The 3-band image was superposed on the sun shaded TC grid of the same survey to produce the final image.
