Spotlight on two products — East Kimberley Reports

GSWA has recently released two Reports on the east Kimberley region. The following abstracts are provided for information on the results.

Report 157 A geophysical investigation of the east Kimberley region, northern Western Australia

The geology of the east Kimberley region was investigated through an integrated geophysical and geological approach. Emphasis was placed on identifying geological structures and features that may be important for assessing the mineral potential of the region. Subsurface architecture was constrained through combined gravity and magnetic modelling along three transects. Significant crustal-scale structures were interpreted and investigated to determine their potential influence on the development of the regional architecture, the emplacement of magma, and the circulation of hydrothermal fluids within the Halls Creek Orogen. Newly interpreted features include three orogen-normal structures, and another regional structure that runs obliquely across the Halls Creek Orogen from beneath the Speewah Dome. The geophysical interpretation delineated a zone of high-grade metamorphic rock that is bounded by two of the orogen-normal structures. A major positive gravity anomaly has been modelled as a source of excess mass in the mid-crust; this is compatible with a large mafic–ultramafic intrusion, or a crustal fragment. We propose a model involving the accretion of this crustal fragment to the Kimberley Craton prior to the 1865–1850 Ma Hooper Orogeny. Accretion of the crustal fragment led to the propagation and creation of the orogen-normal and oblique structures. The structures represent weak zones in the crust, which may have led to differential exhumation of crust during the 1835–1810 Ma Halls Creek Orogeny, and formed fluid conduits in a mineral system.

Report 159 Prospectivity analysis of the Halls Creek Orogen, northern Western Australia — using a Mineral Systems Approach

Opening up greenfields regions of Western Australia for mineral exploration programs is best facilitated through the understanding of regional mineral prospectivity. A multi-commodity mineral systems analysis has been carried out as the basis for prospectivity analyses and mapping in the greenfields Halls Creek Orogen in northern Western Australia. Known mineral occurrences or deposits in the region formed from c. 1860 to 350 Ma, largely influenced by periods of supercontinent assembly and breakup, manifested in the region through the contractional 1865–1850 Ma Hooper and 1835–1805 Ma Halls Creek Orogenies and the 1000–800 Ma Yampi, c. 560 Ma King Leopold, and 450–295 Ma Alice Springs Orogenies interspersed with periods of relaxation accompanied by extension and basin formation.

Prospectivity models were generated for seven commodity groups of various ages and ore genesis mechanisms within the region that include combinations of Ni, Cu, PGE, V, Ti, Au, Pb, Zn, and diamonds. A link was found between key mineral systems and prospectivity model components and the distribution of disparate styles of mineral deposits in the region. Crustal-scale tectonic architecture was analysed by combining a 2D map view geological–geophysical interpretation with 2.5D magnetic and gravity joint inversions of selected profiles, a 3D Moho gravity inversion (MoGGIE), and inferences derived from a 2D magnetotellurics experiment conducted in the northern part of the region. Different ‘zones’ (tectonic terranes) of the Halls Creek Orogen are prospective for diverse commodity groups due to the tectonic environment in which they developed through time, their potential to be preserved at the present day surface or subsurface, and favourable depositional sites that may be present in these zones (structural or lithological). Major crustal-scale faults or shear zones that intrinsically control the location of known ore deposits in the area are implied to be sites of fluid migration and proximal to sites of ore deposition. Of these, orogen-perpendicular (northwesterly trending) and orogen-oblique (northerly trending) faults seem to be the most influential structures with respect to ore deposition in the Halls Creek Orogen, especially in regions where they intersect each other or orogen-parallel (northeasterly trending) major crustal-scale structures.
