Mineral occurrences of Northern Territory of Australia provided by Northern Territory Geological Survey (NTGS) using the EarthResourceML Lite 1.0 data standard for mineral occurrences.

14km depth slice from the northern Australia AusLAMP resistivity model.

An open Sahul-wide database of published aeolian, fluvial, and lacustrine sedimentary records with radiometric ages.

This is the mineral subset of the NSW drilling dataset available from Geoscientific Data Warehouse. The drillhole data has been compiled over time from various sources including mineral exploration reports and departmental records.It provides drill collar information for mineral drillholes and associated data including classification of drilling purpose, drill type, licencee/driller information, date the hole was drilled and depth of hole drilled, azimuth/dip and references. This data is part of the New South Wales Geoscientific Data Warehouse (NSW GDW) series.

This is an interpolated grid of Lu-Hf residence time estimates, based on (primarily zircon) Lu-Hf isotopic analyses from igneous rocks. The data provides an estimate of the duration for material residing in the crust prior to its last melting event. The point data used for the interpolation is the median magmatic residence time data from the summary Lu-Hf dataset held in the Isotopic Atlas as of February 2021. Point data added to the Isotopic Atlas after February 2021 is not represented in this grid. The grid was generated with Esri's ArcMap Spatial Analyst interpolation tool using the Natural Neighbor algorithm and 0.01 degree cell size. Two classifications are provided for this grid; a Jenks natural breaks classification with ten classes (classification 1) as per Champion (2013) http://pid.geoscience.gov.au/dataset/ga/77772, and; the same seven-class interval binning and colour scheme applied to the source point data in the Lu-Hf Isotopes - Summary Data layer (classification 2).

The Field Observations (FieldObs) database stores observations and measurements of rocks collected by the Geological Survey of NSW. Includes location information, stratigraphic unit, links to mineral occurrence and drill hole data, photo and sketch captions, structural measurements and observations, lithology and rock descriptions, sample collection information, and petrophysical measurements (magnetic susceptibility, radioelement and density).
