MgOH Group Composition
The National ASTER Map of Australia is the parent datafile of a dataset that comprises a set of 14+ geoscience products made up of mosaiced ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) scenes across Australia.
ASTER calibration, processing and standardisation approaches have been produced as part of a large multi-agency project to facilitate uptake of these techniques and make them easily integrated with other datasets in a GIS.
Collaborative research, undertaken by Geoscience Australia, the Commonwealth Scientific Research Organisation (CSIRO) and state and industry partners, on the world-class Mt Isa mineral province in Queensland was completed in 2008 as a test-case for these new methods.
For parent datafile information, see the dataset record: http://pid.geoscience.gov.au/dataset/ga/74347
Band ratio: B7/B8
- Blue-cyan is magnesite-dolomite, amphibole, chlorite
- Red is calcite, epidote, amphibole
Useful for mapping:
(1) exposed parent material persisting through "cover";
(2) "dolomitization" alteration in carbonates - combine with Ferrous iron in MgOH product to help separate dolomite versus ankerite;
(3) lithology-cutting hydrothermal (e.g. propyllitic) alteration - combine with FeOH content product and ferrous iron in Mg-OH to isolate chlorite from actinolite versus talc versus epidote; and
(4) layering within mafic/ultramafic intrusives
