  • Biostratigraphic analysis of macrofossils extracted from samples taken from BMR Mt Isa 1 well

  • This document is a professional opinion, presenting an assessment of the macrofossils present in well CKAD0001, located in the Northern Territory in the Georgina Basin.

  • A preliminary report on these samples was forwarded on 19/2/'42, the final report being delayed until the results of a mineralogical examination of two rock types, prominent in samples from 1542 feet down to 1549 feet was available. The results of this examination are now available.

  • biostratigraphic analysis of macrofossils from CRAE Scarr 1 drillhole

  • macrofossil biostratigraphic analysis of samples taken from Cambrian units in GSQ Mt Whelan 1 well

  • Stratigraphic drill hole NDI Carrara 1 was drilled as a collaboration between Geoscience Australia (GA), the Northern Territory Geological Survey (NTGS) and the Mineral Exploration Cooperative Research Centre (MinEx CRC). It reached a total depth of 1751 m in late 2020 and is the first drill hole to intersect the undifferentiated Proterozoic rocks of the Carrara Sub-Basin. It intersected approximately 630 m of Cambrian Georgina Basin sedimentary rocks overlying the ~1100 m of Proterozoic carbonates, black shales and other siliciclastics of the Carrara Sub-Basin succession. The formational assignments of the Georgina Basin succession are preliminary and were assigned in the field. The units intersected comprise the Border Waterhole Formation (~531m to ~630m), which is overlain by the Currant Bush Limestone (~249m to ~531m), which in turn is overlain by the Camooweal Dolostone (0m to ~249m). Of these, only the lower 80% of the Currant Bush Limestone and the entire Border Waterhole Formation were cored. This report presents biostratigraphic results from macrofossil examination of NDI Carrara 1 core samples within the Georgina Basin section.

  • The series of samples forwarded for micro-palaeontological examination was from the depth of 1275 feet down to 1553 feet and was in continuation of that reported upon on 19/1/42.

  • This product is a rendered 3D model of one of the five ACT fossil emblem candidates, the brachiopod Atrypa duntroonensis. The format of the file is ply. or Polygon File Format, and it is designed to store 3D data. The model requires no post-scanning manipulation as it is already complete. The purpose of this is to make this file format publicly available to local school communities so they can 3D print the fossil emblems themselves and engage students with Earth science related topics. <b>Acknowledgement:</b> Computed Tomography (CT) Scans and models generated at <a href="https://ctlab.anu.edu.au/">CTLab</a> - National Laboratory for X-Ray Micro Computed Tomography, Research School of Physics, The Australian National University (ANU), Canberra.
