Online geoscience information systems

You can access a wide range of geoscience information online through the systems outlined below.


The spatial territory resource information kit for exploration (STRIKE) is a web-mapping application for geoscientific data and minerals and energy tenure information in the NT.

STRIKE contains up-to-date information on all of the following:

  • title applications
  • granted titles and reserved areas
  • geology including drilling and geochemistry
  • geophysical images and remote sensing
  • mineral occurrences
  • indexes to open file reports and geophysical surveys.

To find out more, go to the STRIKE website.


The geoscience exploration and mining information system (GEMIS) provides access to the following information collections:

  • mineral exploration industry reports and data
  • energy exploration reports
    • petroleum geophysical survey reports and data
    • petroleum well reports and data
    • petroleum and geothermal tenure reports
  • Northern Territory Geological Survey (NTGS) products:
    • reports
    • annual geoscience exploration seminar proceedings
    • maps
    • datasets
  • core sampling reports and data.

To find out more, go to the GEMIS website.

Minerals and energy library catalogue

You can search the minerals and energy libraries' holdings through the library catalogue.

Read more about the libraries.

Exploration news database

Exploration news is a weekly update providing summaries of NT exploration and mining news published in:

  • industry journals
  • media releases
  • stock exchange announcements.

The database is compiled and maintained by the Minerals and Energy InfoCentre.

Access the exploration news database.


The drill core database (COREDAT) is a catalogue of drill core and cuttings held in the NTGS's core libraries.

Read more about accessing the drill core library or go to the COREDAT database.

Core sampling reports

The core sampling reports database is a catalogue of reports and data from sampling on drill cores held in the NTGS core libraries.

To find out more, go to the core sampling reports database.

National virtual core library

The geological surveys of Australia are building a virtual core library of high-resolution imagery and mineralogical data from hyperspectral scanning of drill core.

The data is collected using the HyLogger™ system.a

To access the hyperspectral data and imagery for the NT, you can:

To find out more about the national virtual core library project, go to the Department of Primary Industry and Resources website.


Through the geophysical image web server (GIWS) you can view and download geophysical survey images in ECW format.

To find out more, go to the GIWS web server.

For more information about NT geophysical surveys, go to the geoscience projects and initiatives section on the Department of Primary Industry and Resources website.


Through the geophysical archive data delivery system (GADDS), you can access the following NT data:

  • magnetic
  • radiometric
  • gravity
  • digital elevation.

GADDS is maintained by Geoscience Australia. It includes data from the Australian national, state and territory government geophysical data archives.

To find out more, go to GADDS.

You can get industry geophysical data through the GEMIS website.

Australian stratigraphic units database

Geoscience Australia maintains the official register of Australian stratigraphic units with details of definitions, relationships, name changes and references.

You can download a list of the stratigraphic units of the NT.

To find out more, go to the Australian stratigraphic units database.
