A Stratigraphic Reconstruction of Bulk Volatile Chemistry from Fluid Inclusions in: Jericho 1

Exploring for the Future (EFTF) is an Australian Government program led by Geoscience Australia (GA), in partnership with state and Northern Territory governments. The EFTF program (2016-2024) aims to drive industry investment in resource exploration in frontier regions of onshore Australia by providing new precompetitive data and information about their energy, mineral and groundwater resource potential. 
Under the EFTF program, GA’s National Hydrogen Project and in collaboration with Minerals Resources Tasmania (MRT) undertook a study of hydrogen and helium potential of south-east Tasmania with the sampling of cores from Jericho 1 on Bruny Island. This well was selected based on the availability of core and historic reports of hydrogen-rich natural gases from this well and petroleum exploration wells in the region. Sampling of cores was done at MRT’s Core Repository in Hobart.
Geoscience Australia commissioned a fluid inclusion stratigraphy (FIS) study on the downhole samples.  Here, volatile components ostensibly trapped with fluid inclusions are released and analysed revealing the level of exposure of the well section to migrating fluids. Integration of thin section (TS) preparations reveal the extent of gas and fluid trapping within fluid inclusions while microthemometry (MT) gives an estimation of fluid inclusion trapping temperature.
For Jericho 1, FIS analysis was performed on 179 cores between 87 m and 640.6 m base depth, together with 7 samples prepared for TS and 1 sample for MT. To support this study, lithostratigraphic tops were compiled by MRT. The results of the study are found in the accompanying documents.

Paterson AEM Survey EM Vision 3D Inversion Data and Release Notes: Kintyre area

Conductivity-depth estimates generated using the 1D Geoscience Australia layered earth inversion algorithm (GA-LEI) have been released to the public domain. The GA-LEI has been shown to provide useful mapping of subsurface conductivity features in the Paterson; for example paleovalleys, unconformities and faults. GA-LEI interpretations have been supported by independent borehole conductivity logs, and lithological drill-hole information. The Geoscience Australia Record 2010/12; Geological and energy implications of the Paterson Province airborne electromagnetic (AEM) survey, Western Australia, summarises the AEM  processing, inversion, interpretation and implications for mineral exploration using the 1D GA-LEI.
There is an inherent assumption in the GA-LEI algorithm that the earth can be represented by a set of 1D layers, which extend to infinite distance in the horizontal plane. This layered earth assumption has some limitations, and has been demonstrated to create artefacts when applied to heterogeneous 3D geological features. 3D inversion methods can potentially overcome some of the limitations of 1D inversion methods, reducing the artefacts of a 1D earth assumption. 
3D inversions require much greater computational resources than 1D methods because they have to solve many large systems of equations. In addition, a large sensitivity matrix is computed, which increases memory requirements, and the process must be repeated for multiple iterations. This computational expense has generally limited the application of 3D inversions to AEM datasets, and restricted its practicality as a general mapping tool. 
The EMVisionÂ® inversion generated by TechnoImaging presents a method of running a 3D inversion, with a runtime comparable to 1D inversion methods. The EMVisionÂ® algorithm uses a moving footprint to limit the number of data points needed as input to the inversion at any one location. A background conductivity model is chosen to represent the far-field response of the earth, and the data points within the AEM footprint are treated as anomalies with respect to the background. 
In 2010, Geoscience Australia decided that a comparison of the GA-LEI with the EMVisionÂ® inversion would be useful both for geological interpretation and for assessing the benefits of 3D inversion of AEM. A subset of the regional Paterson AEM dataset around the Kintyre uranium deposit was provided to TechnoImaging to create a 3D inversion using EMVisionÂ® software. The data subset was a combination of GA data and data owned by Cameco Corporation and the cost of inversion by TechnoImaging was shared by both parties. Under the terms of the agreement between Cameco Corporation and Geoscience Australia there was a moratorium on the data release until 2012.

Ashton thorium grid

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 radiometric thorium grid has a cell size of 0.00083 degrees (approximately 91m) and shows thorium element concentration of the Ashton, WA,1994 in units of parts per million (or ppm). The data used to produce this grid was acquired in 1993 by the WA Government, and consisted of 51484 line-kilometres of data at 400m line spacing and 60m terrain clearance.

The Mindyallan fauna of north-western Queensland

This Bulletin is the third of a series of Bulletins dealing with the palaeontology and stratigraphy of the Cambrian of Queensland, as well as of Aus.tralia in general. This Bulletin, dealing with the Mindyallan and its fauna, fills a hitherto bl~mk interval in the Australian Cambrian sequence and supplies amplifying information regarding the geological and biological history of the early Upper Cambrian in general. Originally, the palaeontology of 'the lower chert bed' of the O'Hara Shale was planned as a part of Bulletin 53 (Opik, 1961), but had to be postponed for technical reasons; subsequently the early Upper Cambrian stratigraphy was presented in Bulletin 64 (Opik, 1963), and all available information from all geological sources is now included in the present contribution. 1 wish to emphasize that all Mindyallan comprehendable forms so far collected are described, regardless of their state of preservation, but that some material remains indicating the existence of forms which need further collecting.

SA Exploration Initiative 1994/95 - Area B16 (P713), magnetic line data, AWAGS levelled

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.
 These line dataset from the SA Exploration Initiative 1994/95 - Area B16 survey were acquired in 1994 by the SA Government, and consisted of 3378 line-kilometres of data at 400m line spacing and 80m 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.

The groundwater quality situation in alluvial aquifers of the Kathmandu Valley, Nepal

Surveys of groundwater quality have been carried out in alluvial aquifers of the Kathmandu valley, Nepal, and a wide range of parameters studied.  The natural groundwaters are characterised by high concentrations of iron, manganese, ammonia and carbon dioxide.  The presence of coliform bacteria in many wells indicates the need for pollution control. Rapid population growth and urbanisation, and an increasing concentration of industries, are contributing to degradation of groundwater quality.  Monitoring programs leading to increased public awareness and management action are necessary at this stage in development.

Lithospheric conductivity structures and mineral potential from magnetotelluric data in northern Australia

Long-period magnetotelluric (MT) data from the Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP), collected as part of Geoscience Australia’s Exploring for the Future program with contributions from the Northern Territory Geological Survey and the Geological Survey of Queensland, provide important first-order information for resolving large-scale lithospheric architecture and identifying the broad footprint of mineral systems in northern Australia. Large-scale crust/mantle conductivity anomalies map pathways of palaeo-fluid migration which is an important element of several mineral systems. For example, the Carpentaria conductivity anomaly east of Mount Isa and the Croydon, Georgetown to Greenvale conductivity anomaly are highly conductive lithospheric-scale structures, and show spatial correlations with major suture zones and known mineral deposits. These results provide evidence that some mineralisation occurs at the gradient of or over highly conductive structures at lower crustal and lithospheric mantle depths, which may represent fertile source regions for mineral systems. These observations provide a powerful means of highlighting prospective greenfield areas for mineral exploration in under-explored and covered regions.

Higher resolution scale-reduction MT surveys refine the geometry of some conductive anomalies from AusLAMP data, and investigate whether these deep conductivity anomalies link to the near surface. These links may act as conduits for crustal/mantle scale fluid migration to the upper crust, where they could form mineral deposits. For example, data reveals a favourable crustal architecture linking the deep conductivity anomaly or fertile source regions to the upper crust in the Cloncurry region. In addition, high-frequency MT data help to characterise cover and assist with selecting targets for drilling and improve the understanding of basement geology.

These results demonstrate that integration of multi-scale MT surveys is an effective approach for mapping lithospheric-scale features and selecting prospective areas for mineral exploration in covered terranes with limited geological knowledge.

Some models in this presentation were produced on the National Computational Infrastructure, which is supported by the Australian government.
