“…Those fluids dissolved carbonates, forming cavity systems in which the sulfides were precipitated. Some mineralization is also interpreted to have replaced Devonian carbonates and evaporites (Tompkins et al, 1994b;Vearncombe et al, 1995). Unlike the exhalative sulfides, the epigenetic Zn-Pb sulfides postdate marine cements, regional dolomitization, and the onset of stylolitization.…”

“…Hot (up to about 90ºC) zinc-, lead-, and iron-bearing brines were probably derived from thick Devonian shales in the Fitzroy trough. The expelled fluids were channeled along faults into carbonates of the Devonian reef complexes on the adjoining Lennard shelf, where Zn-Pb sulfides were precipitated in fractured carbonates, hydrothermal karst cavities, and evaporitic beds (Vearncombe et al, 1995).…”

“…THERE IS A consensus view that the economic Zn-Pb mineralization known in Devonian reef complexes of the Lennard shelf, in the Canning basin of Western Australia, is epigenetic (Ringrose, 1989;Murphy, 1990;McManus and Wallace, 1992;Tompkins et al, 1994a, b;Christensen et al, 1995;Vearncombe et al, 1995). However, an earlier phase of syngenetic mineralization, associated with stromatolite buildups, has recently been recorded in the same general area and is interpreted to have formed as mounds over cool-fluid seepages on the sea floor (De Kever, 1998;Mason, 1998;Playford and Wallace, 1998;.…”

Devonian Reef Complexes of the Canning Basin Devonian reef complexes are well exposed on the Lennard shelf, the northernmost structural subdivision of the Canning basin, forming a series of limestone ranges some 350 km long (Fig. 1). The reef complexes were constructed as shallow reef-fringed limestone platforms, fronted by steeply dipping marginal-slope deposits, which descended into flat-lying basin deposits in water up to several hundred meters deep (

“…Despite this limited success over several decades, the newest conventional oil discovery in the Fairfield Group in 2011 highlights continued prospectivity. The older Frasnian platforms are better known as hosts of Mississippi Valley‐type sulphide deposits for which the importance of faulting in their formation has also been emphasised (Vearncombe et al ., ; Wallace et al ., ; Miller et al ., ).…”

Stratal architecture and platform evolution of an early Frasnian syn‐tectonic carbonate platform, Canning Basin, Australia

et al. 2013

Facies architecture and platform evolution of an early Frasnian reef complex in the northern Canning Basin of north-western Australia were strongly controlled by syn-depositional faulting during a phase of basin extension. The margin-attached Hull platform developed on a fault block of Precambrian basement with accommodation largely generated by movement along the Mount Elma Fault Zone. Recognition of major subaerial exposure and flooding surfaces in the Hull platform (from outcrop and drillcore) has enabled comparison of facies associations within a temporal framework and led to identification of three stages of platform evolution. Stage 1 records initial ramp development on the hangingwall dip slope with predominantly deep subtidal conditions that prevented any cyclic facies arrangements. This stage is characterised by basal siliciclastic deposits and a major deepening-upward facies pattern that is capped by a sequence boundary towards the footwall (north-west) and a major flooding surface towards the hangingwall. Stage 2 reflects the bulk of platform aggradation, significant platform growth towards the hangingwall and the development of reef margins and cyclic facies arrangements. Thickening of this stage towards the hangingwall indicates that accommodation was generated by rotation of the fault block and overlying platform. Stage 3 records a major flooding and backstep of the platform margin. The Hull platform illustrates important elements of margin-attached carbonate platforms in a half-graben setting, including: (i) prominent, but limited, coarse siliciclastic input that does not have a major detrimental effect on carbonate production near the rift margin in arid to semi-arid settings; (ii) wedge-shaped accommodation created by syn-depositional rotation of fault blocks and tilting of the hangingwall dip slope, resulting in shallowwater facies and subaerial exposure up-dip of the rotational axis and deeper water facies down-dip; and (iii) evolution of a ramp to rimmed shelf, coincident with a sequence boundary-flooding surface, that is accelerated by tilting of the hangingwall dip slope during fault-block rotation.

“…The Kidson Sub-basin also contains the largest halite formation in Australia (Hashimoto et al, 2018), one a the most cost-effective methods for underground hydrogen storage (Lord et al, 2014). The Sub-basin also has significant mineral resource prospectivity, such as for Uranium (Botten, 1984) and sediment-hosted base metals (McCracken et al, 1997;Passmore and Towner, 1987;Ringrose, 1984;Veamcombe et al, 1995).…”
