Description
Harris Greenstone Domain GIS data delineates a late Archean-Proterozoic tectonostratigraphic terrane within South Australia's Gawler Craton. The dataset characterizes the Archean Harris Greenstone Belt, including komatiite, basalt, and banded iron formation, metamorphosed during the ~2440 Ma Sleafordian Orogeny. Its interpretation is based on aeromagnetic and gravity surveys, supplemented by diamond drillcore, to map structures beneath thin Quaternary and Eocene cover.
Use Cases
Mineral prospectivity mapping based on interpreted lithology and magnetic signatures.
Structural geology analysis of the Yerda Shear Zone and other domain boundaries.
Regional geological modeling using integrated aeromagnetic and gravity data.
Target generation for nickel-copper-PGE exploration in the Lake Harris Komatiite.
Stratigraphic correlation of Archean and Proterozoic rock units within the Gawler Craton.
Strengths
Covers a significant geological feature described as the most eastern occurrence of komatiite in Australia.
Integrates multiple data sources, including aeromagnetics, gravity, and diamond drillcore.
Provides detailed lithological and structural descriptions for a 250K scale region.
Limitations
Metadata completeness is low: column names, row counts, size, license, and author are unknown.
The dataset's physical exposure is poor, with interpretations relying heavily on geophysics.
