Geothermal constraints on the hydrocarbon potential of the Canning Basin, Western Australia

Limited quantities of hydrocarbons have been recovered from only three of the 96 exploration wells drilled in the Canning Basin. Although unsuitable reservoir and entrapment situations account for much of this poor record, part of the total lack of commercial success is thought to be related to the nature of potential source rocks and their level of maturation. Temperature is considered to be the most important influence on the maturation process. Despite their inaccuracy, logging run temperatures have been used to delineate regional thermal trends. Geothermal gradients are high over positive structural elements, and low in the deep pre-Permian basins; they show an inverse relation with depth to magnetic basement. Some anomalously high gradients occur near deep-seated faults and may result from upward migration of hot waters. Palaeotemperatures were derived from vitrinite reflectance measurements in 16 wells; in most areas, with the exception of anticlines in the Fitzroy Graben, they approximate present temperatures. Formation temperatures in these anticlines were reduced following pronounced uplift during Triassic tectonism. The simple relationship of past and present temperatures allows a direct comparison between indicators of organic metamorphism and present temperatures. Such a comparison reveals that in Palaeozoic rocks onshore, the zone of oil generation lies between the 50Â° and 75Â°C isotherms. This relatively low temperature range of the liquid window reflects the prolonged burial of the Palaeozoic sediments. Offshore, predominantly immature Mesozoic sediments overlie supermature Palaeozoic sediments. Reservoir and thermal considerations limit prospective areas to the Permian and Carboniferous sediments of the Lennard Shelf, Fitzroy Graben and Kidson Sub-basin. Source-rock studies may further reduce the viable exploration areas.

Vegetation Cleared Dataset for Recharge Discharge Project

This dataset is a union of the Integrated Vegetation Cover 2009 (IVC)obtained from BRS and the draft version of the Dynamic Land Cover Map based on MODIS Data, obtained from Geoscience Australia. 
The categories for this dataset are No, Yes, Requires further investigation, Urban and Water.
The IVC dataset was classified into Cleared (annual crops and built up areas), Not Cleared (native forests, shrublands, plantations, perennial crops and water bodies) and Further Investigation Required (native grasslands and minimally modified pasture, horticultural trees and shrubs).
The draft version of the Dynamic Land Cover Map presents land cover information for every 250m by 250m area of the country from April 2000 to April 2008. The classification scheme used to describe land cover categories in the Dynamic Land Cover Map conforms to the 2007 International Standards Organisation (ISO) land cover standard (19144-2).  These reflect the structural character of vegetation, ranging from cultivated and managed land covers (crops and pastures) to natural land covers such as closed forest and sparse, open grasslands. 
This dataset was reclassified into Cleared, Not Cleared and Further investigation required.
Cleared - Extraction Sites, Bare Areas, Rainfed Cropping, Irrigated Cropping and Irrigated Pasture and Rainfed Pasture 
Not Cleared - Wetlands, Forbs (open and closed), Tussock, Alpine and Hummock Grasses (Open, Closed and sparse), Shrubs (open and closed), Rainfed Sugar, Irrigated Sugar and Trees (Open, closed, scattered and sparse) and water bodies.
To obtain urban areas, the dataset was unioned with the 250k topographic map series obtained from Geoscience Australia.
These two datasets were joined together and where they correlated, ie both cleared, or both not cleared, were labelled accordingly, and where there was a conflict it was classified as Further investigation required.

A new structure in pollen assigned to Striatopodocarpites Sedova 1956 and Protohaploxypinus Samoilovich emend. Morbey 1975, from the Late Permian (Tatarian) of the Russian Platform

Certain species of Striatopodocarpites Sedova 1956 and Protohaploxypinus Samoilovich emend. Morbey 1975, from Late Permian assemblages from the Russian Platform, have a ring tenuitas which surrounds and outlines the striate cappa of the proximal face. For many grains, occurring as sporae dispersae, the cappa is often detached and can be identified as a separate striate entity resembling, superficially, members of other genera such as, Vittatina Samoilovich 1953, Fusacolpites Bose and Kar 1966, and Weylandites Bharadwaj and Srivastava 1969. As the types for both Striatopodocarpites and Protohaploxypinus are lost, and it is not possible to determine if they also have a proximal tenuitas, the taxonomic consequences of the present study are currently uncertain. Both generic names have been applied to specimens from the Gondwanan Permian, but the apparent incidence of grains with this feature is rarer than in the Russian assemblages. Further work may show this to be a useful criterion to distinguish otherwise similar pollen from the Angaran/ Euramerian Floral Province and the Gondwanan Floral Province.  We suggest that this proximal construction may have been part of the germinal mechanism of these grains. lllinites Kosanke 1950, a characteristic element of Late Carboniferous- Early Permian Euramerian palynofloras, also possesses a proximal ring tenuitas, which suggests a possible phylogenetic link between these genera .

Napperby/Hermannsburg2 3, NT, 1997 (P1002), 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 Napperby/Hermannsburg2 3, NT, 1997 (P1002), radiometric line data, AWAGS levelled were acquired in 1997 by the NT Government, and consisted of 105377 line-kilometres of data at 400m line spacing and 60m 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.

Darwin Harbour Habitat Mapping Program: Predicted standard error for interpolated surface of Chlorin Index in sediments

This resource contains a predicted chlorin index standard error grid for the greater Darwin Harbour region as part of a baseline seabed mapping program of Darwin Harbour and Bynoe Harbour. This project was funded through offset funds provided by an INPEX-led Ichthys LNG Project to the Northern Territory Government’s Department of Environment and Natural Resources (NTG-DENR) with co-investment from Geoscience Australia (GA) and the Australian Institute of Marine Science (AIMS). The intent of this program is to improve knowledge of the marine environments in the Darwin and Bynoe Harbour regions by collating and collecting baseline data that enable the creation of thematic habitat maps and information to underpin marine resource management decisions. The predicted chlorin index standard error grid was derived from a compilation of multiple surveys undertaken by GA, AIMS and NTG-DENR between 2011 and 2017, including GA0333 (Siwabessy et al., 2015), GA0341 (Siwabessy et al., 2015), GA0351/SOL6187 (Siwabessy et al., 2016), GA4452/SOL6432 (Siwabessy et al., 2017), GA0356 (Radke et al., 2017), and GA0358 and GA0359 (Radke et al., 2018), adding to those from previous surveys GA4425 and GA0333 collected by GA, AIMS, NTG-DENR and Darwin Port Authority.
