“…Following Paleozoic cooling, samples resided in a near surface environment through to the present day. We interpret Paleozoic cooling as a significant denudational event and suggest that the unroofed and denuded sediments were deposited in the adjacent Canning Basin (Figure 1) in accord with the basin's infilling history (Figure 2; Hashimoto et al, 2018; Romine et al, 1994; Shaw et al, 1995). Although, some Canning Basin infill also had contributions from far‐field sediment sources (Haines et al, 2013; Morón et al, 2019).…”

“…Basin formation and infilling adjacent to the Pilbara Craton (Figure 1) occurred from the Early Ordovician to the Early Cretaceous (Hashimoto et al, 2018; Kennard et al, 1994; Shaw et al, 1995). In the Canning Basin, adjacent to the craton, Lower Paleozoic sedimentary packages range between 1 and 2.5 km thick (Figure 2) (Hashimoto et al, 2018). Glacially striated basement rocks (mostly in the northeastern Pilbara) and intraformational glacial striae in Permian sandstone provide evidence that glacial erosion related to the pervasive Permo‐Carboniferous glaciation of Gondwana extended as far as the Pilbara Craton and the onshore Canning Basin (Gzhelian‐Sakmarian ca.…”

Denuding a Craton: Thermochronology Record of Phanerozoic Unroofing From the Pilbara Craton, Australia

Cratons are ancient regions of relatively stable continental fragments considered to have attained long-term tectonic and geomorphic stability. Low-temperature thermochronology data, however, suggest that some cratons have experienced discrete Phanerozoic heating and cooling episodes. We report apatite fission track, and apatite and zircon (U-Th)/He low-temperature thermochronology data from the Archean Pilbara craton and adjacent Paleoproterozoic basement, NW Australia. Inverse thermal history simulations of this spatially extensive data set reveal that the region has experienced~50-70°C cooling, which is interpreted as a response to the unroofing of erodible strata overlying basement. The timing of cooling onset is variable, mainly~420-350 Ma in the southern and central Pilbara-eastern Hamersley Basin and~350-300 Ma in the northern Pilbara, while the westernmost Pilbara-central Hamersley Basin does not record a significant Paleozoic cooling event. These differences are attributed to variations in sedimentary thickness and proximity to adjacent rift basins, which lack Archean age zircons in their Paleozoic strata. The onset of Paleozoic cooling coincides with the timing of the episodic intraplate late Ordovician-Carboniferous Alice Springs Orogeny. This orogeny is thought to have resulted from far-field plate margin stresses, which in turn caused the opening of the adjacent Canning Basin, to the north and east of the craton. We propose that basin development triggered a change of base level, resulting in denudation and the crustal cooling event reported here. Our results provide further evidence for the transmission of far-field forces to cratons over hundreds of kilometers and support the view that cratons have experienced geomorphic changes during the Phanerozoic.

“…These two major depocentres are separated by the Broome and Crossland Platforms (e.g. Hashimoto et al, 2018), a northwest-southeasttrending platform of shallow basement. The onshore sedimentary succession comprises a Lower Ordovician to Lower Cretaceous succession up to 15 km thick in the Fitzroy Trough-Gregory Sub-basin and up to 5 km thick in the Willara Sub-basin-Kidson Sub-basin.…”

Hashimoto et al (2018) reviewed the available data within the Canning Basin and identified a significant seismic data gap across the Kidson Sub-basin.…”
