Online geoscience information systems

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


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.



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
  • Northern Territory Geological Survey (NTGS) products: reports, AGES proceedings, maps and datasets
  • core sampling reports and data

Read more about accessing geoscience information.

Go to GEMIS.


The petroleum exploration reports (PEX tenure) is a catalogue of publically available petroleum geological studies submitted with petroleum annual reports. Read more about exploration reports and data.

Go to PEX.

You can also search for some NT petroleum data on Geoscience Australia’s petroleum databases. Go to the Geoscience Australia website for more information.

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

Exploration News is a weekly update providing summaries of NT exploration and mining news published in industry journals, media releases and stock exchange announcements. The database is compiled and maintained by the Minerals and Energy InfoCentre.

Access Exploration News


COREDAT is a catalogue of drill core and cuttings held in the Northern Territory Geological Survey's core libraries. Read more about accessing the drill core library.


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.

Go to core sampling reports.

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.

Access the hyperspectral data and imagery for the NT via the geoscience portal on the AUSGIN website or request HyLogger™ Data Packages through GEMIS.

Go to the Department of Primary Industry and Resources website for more information on the national virtual core library project.


Through the Geophysical Image Web Server (GIWS) you can view and download geophysical survey images in ecw format.

Go to GIWS

For more information about NT geophysical surveys go to the Department of Primary Industry and Resources website.


Through the Geophysical Archive Data Delivery System (GADDS) you can access NT magnetic, radiometric, gravity and digital elevation data. GADDS is maintained by Geoscience Australia and includes data from the Australian national, state and territory government geophysical data archives.

Go to GADDS.

You can get industry geophysical data through GEMIS.

Australian Stratigraphic Units Database

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

A list of the stratigraphic units of the Northern Territory can be downloaded.

Go to the Australian Stratigraphic Units Database.
