From the early 1960s through to the 1990s Geoscience Australia's predecessors conducted numerous remote field programs, mapping the geology of the Australian Antarctic Territory. Scientific observations, measurements, sample numbers, locations, and other anecdotal information, such as weather conditions and day-to-day life in the field during those early Australian National Antarctic Research Expeditions, were faithfully and sometime painstakingly, recorded in that quintessential accessory, 'the field notebook', by field geologists. These handwritten field notebooks now reside in the Geoscience Australia library, and are publicly available for all to enjoy. Currently, the interested geologist or historian must physically visit Geoscience Australia to gain access to these irreplaceable and invaluable sources of scientific and other information. The Geoscience Australia library regularly receives requests from researchers to view field notebooks, as the raw data contained is of continued relevance and value to contemporary scientific research. In addition to the scientific observations, the notebooks record the realities of what everyday life in Antarctica was like. Among the scientific data are lists of food supplies, field logistics and planning, equipment requirements, comments on the dog sledge teams, and WYSSA (private telegram) messages home to loved ones. Increasingly, we are finding that family historians are keen to access their relative's field notebooks for inclusion in their own publications and family histories. In order to make these valuable records more accessible to the world and in line with Geoscience Australia's policy of ensuring that our geoscience data, information, and collections are discoverable, accessible and searchable as a public resource a digitisation project has been undertaken. Under the guidance and assistance of the Australian Museum's DigiVol program (https://volunteer.ala.org.au/), and with a loyal cadre of hardworking volunteers, we are digitising and transcribing all the Antarctic field notebooks for web delivery. Thanks to the hard work of our dedicated volunteers, our collection of almost 90 Antarctic field notebooks is well on its way to being released. Although the Geoscience Australia library has a comprehensive collection of Antarctic field notebooks, we do have some gaps which we are keen to fill. We¿d like to hear from anyone who has any Bureau of Mineral Resources, Australian Geological Survey Organisation, or Geoscience Australia Antarctic field notebooks that we could include in our project, to make the important information contained in them accessible to researchers from around the world.

<div>This study is part of the Mineral Potential Assessment (MPA) module of Geoscience Australia's Darling-Curnamona-Delamerian (DCD) project, a deep-dive project within the Exploring for the Future Program (EFTF) 2020-2024. An objective of the DCD project is to further the understanding of the geological architecture of the Delamerian Orogen into a cohesive framework enable a regional mineral potential assessment of this under-explored and mostly under cover Orogen. The MPA module is one of eight modules under the umbrella of the DCD project. To facilitate assessment of the mineral potential of the project area, the mineral potential assessment study has 3 key scientific objectives: (1) Defining the characteristics of the mineral systems / prospects. (2)&nbsp;&nbsp;Evaluating the temporal framework of the formation of mineral systems / prospects; and (3) Understanding the regional magma fertility. This study delivers Objective 1, i.e., outlining the principle geological and metallogenic characteristics of reported mineral prospects in the project area.&nbsp;</div><div><br></div><div>Legacy drill cores best demonstrating metallogenic features of different mineral system types at key prospects across the project area were selected for viewing and sampling following review of historical exploration reports and assay results. Four sets of data are included in the appendices of this report: (1)&nbsp;&nbsp;HyLogger spectral images of 20 drill holes of 8 prospects in New South Wales. (2)&nbsp;&nbsp;143 high-resolution scan files of legacy drill core samples across the project area. (3)&nbsp;&nbsp;16 microscopic images of thin sections for 4 prospects of the Loch Lilly-Kars Belt, New South Wales. (4)&nbsp;&nbsp;53 Backscattered Electron (BSE) images and 53 Advanced Mineral Identification and Characterization System (AMICS) high-resolution mineral maps of 53 samples from 18 prospects across the whole Delamerian Margin.&nbsp;</div><div><br></div><div>Metallogenic characteristics of samples from four different mineral deposit types were studied, along deposits of uncertain affiliation (referred here as undefined systems), including (1) Porphyry-epithermal mineral systems. (2)&nbsp;&nbsp;Volcanic hosted massive sulfide (VHMS) mineral systems. (3)&nbsp;&nbsp;Orogenic gold mineral systems. (4)&nbsp;&nbsp;Mafic-ultramafic Cu-Ni-PGE mineral systems. (5)&nbsp;&nbsp;Metallogenetically undefined systems. Detailed metallogenic characteristics of the samples from 22 key prospects in Delamerian Orogen are documented in this report.&nbsp;&nbsp;</div><div><br></div><div>This is the first systemic study on the essential metallogenic characteristics of the mineral systems in Delamerian. The characterisations outlined in this report are foundational for understanding the regional metallogenesis and assessing the potential of multiple types of mineral systems in the Delamerian Belt, which should be useful in both academic and the mineral exploration sector.</div><div><br></div><div>The high-resolution BSE and AMICS mineral maps are available at Geoscience Australia.
