HyLogger scanning services and data

National Virtual Core Library NT

The AuScope National Virtual Core Library (NVCL) is a component of a collaborative research infrastructure project funded by the Federal Government's National Collaborative Research Infrastructure Strategy (NCRIS).

The project involves collaboration between CSIROAuScope and most of the State and Territory geological surveys.

The NVCL's primary goal is to progressively build an Australia-wide drill core database comprising high-resolution imagery and mineralogical data from spectroscopic scanning. The data can be used to further the understanding of the properties of the upper one to two kilometres of the Australian crust and to facilitate geoscience research. The data are being collected using CSIRO's HyLogger™ system then are processed and interpreted using The Spectral Geologist (TSG) software.

In late February 2010, the Northern Territory Geological Survey (NTGS) received its HyLogger at its Core Library Facility in Darwin. In June 2011, the HyLogger was upgraded with the addition of a thermal infrared (TIR) spectrometer, which allows for the identification of more minerals (such as quartz, feldspars and other silicates).

The NVCL Database is accessible through both the AGSON Portal (Australian Geological Survey Organisations Network) and the AuScope Portal, and comprises data from almost all the State and Territory geological surveys.

Several external organisations have taken advantage of the HyLogger being available to Industry and Research groups. For more information or to request core scanning, please email geoscience.info@nt.gov.au

Outputs

As well as data output via the NVCL framework, NTGS also provides integrated datasets from focal areas as interpreted data packages as part of its HyLogger program.

Initially, a small number of interpreted datasets were released as NTGS Records but since 2013, interpreted datasets are released as HyLogger Data Packages (HDP). These data packages are available via the NTGS Geoscience Exploration and Mining Information System (GEMIS).

Each HDP covers a single drill hole and contains a summary of the major findings, including a comparison of existing stratigraphic logs with mineral domain boundaries as identified in the hyperspectral data. The Spectral Geologist (TSG) format datasets can be viewed using the (free) TSG Viewer and include high resolution imagery of the core.

In addition to the individual HyLogger Data Packages, interpretations across a number of holes in a region may be released via GEMIS as NTGS Records and some ad hoc, smaller informational reports, for example a comparison of mineral matches from the HyLogger with XRD mineral results, are also issued.

The spatial distribution of HyLogged drillholes across the Northern Territory, along with associated drillhole header information and links to download high-resolution core photography for each drillhole, are given in the “HyLogged Drillholes” layer in STRIKE, the NTGS spatial geoscience data viewer.

A catalogue detailing which drillholes have been HyLogged by the NTGS, what processed TSG datasets are currently available, links to any relevant NTGS Records/HDP, and links to download high-resolution core photography is available via GEMIS.

Processed TSG datasets are available from the NVCL via the AGSON Portal and the AuScope Portal, and on request from NTGS via email at geoscience.info@nt.gov.au.

To access data and reports on hyperspectral data including HDPs, search the NTGS product catalogue.

Where Advanced HyLogger datasets (which have undergone processing and user interpretation) are not yet available, Basic HyLogger datasets (which have undergone processing and automated interpretation) and core photography can be provided on request from NTGS via email at geoscience.info@nt.gov.au.
