L008 seismic survey of the Nerrima Dome, WA, 1953

This report contains the results of a seismic survey on the Nerrima Dome, a major structure within the Fitzroy Basin and near its south-western boundary. The dome is situated near the Fitzroy River about 100 miles south-east of Derby in the West Kimberley district of Western Australia.
The Nerrima Dome has been mapped at the surface in Permian sediments and is a complex structure. It was desired to determine if the dome existed at depth and, if not, the structure at depth, with a view to locating a site for a deep drilling test. The target beds for such a test are Devonian and/or Ordovician sediments over which the Permian sediments are believed to lie unconformably. Reflection methods were tried and proved unsuccessful and the survey was carried out using refraction methods.
Although the structure underlying the dome has not been clearly shown, the refraction method has indicated that it is complex and does not conform with the domal structure at the surface. There appears to be a major unconformity at comparatively shallow depth (2000 ft). The deep structure (7000 ft) although apparently less
complex than that immediately below the unconformity, also bears no obvious relation to structure at surface. The results so far obtained are reasonably conclusive in showing that no simple dome-like structure of large magnitude exists under the Nerrima Dome.

Mid- to lower-crustal architecture of the northern Lachlan and southern Thomson orogens—evidence from O-Hf isotopes

The nature of the substrate below the northern Lachlan Orogen and the southern Thomson Orogen is poorly understood. We investigate the nature of the mid- to lower-crust using O and Lu-Hf isotopes on zircons from magmatic rocks which intrude these regions, and focus on the 440–410 Ma time window to minimise temporal effects while focussing on spatial differences. Over the entire region, O-isotope values range from δ18O = 5.52‰ to 10.14‰, and Lu-Hf from εHft = -8.1 to +8.5. In the northern Lachlan Orogen and much of the southern Thomson Orogen, magmatic rocks with low εHft (c. -8 to -4) and elevated δ18O (c. 9 to 10‰) reflect a supracrustal source. Magmatic rocks intruding the Warratta Group in the western part of the Thomson Orogen also have low εHft (c. -10 to -6) but more subdued δ18O (c. 7‰), indicating a distinct supracrustal source in this region. In the northeast Lachlan Orogen, magmatic rocks record mixing of the supracrustal source with input from a juvenile source (εHft as high as +8.5, δ18O as low as 5.52‰), most likely of “Macquarie Arc”-type affinity. Samples in the west-southwest Thomson Orogen also record some evidence of juvenile input (εHft as high as +0.2, δ18O as low as 6.51‰), likely the Mount Wright Arc of the Koonenberry Belt. Our results show that internal isotopic variation within the Lachlan and the Thomson orogens is much greater than the difference between the two orogens.

First insights into the deep structure across the Tasman Basin and Lord Howe Rise from wide-angle seismic data

The eastern Australian margin was shaped during the fragmentation of eastern Gondwana in the late Cretaceous. This led to the opening of the Tasman Basin and to the formation of sub-parallel rises, ridges and basins, including the Lord Howe Rise (LHR). The driving forces controlling the rifting are not fully understood, and two processes are invoked: slab rollback associated with back-arc extension or a plume impinging the lithosphere. To better understand the deep structure of the region, a 680km long seismic profile incorporating 100 ocean-bottom seismometers was acquired conjointly with multi-channel seismic (MCS) reflection data onboard the R/V Kairei at 27.2°S (March ¿ May 2016). Beneath the 4800m deep Tasman Basin, the OBSs register clear refracted arrivals from the crust and the mantle that are recorded at very large offsets of up to 250km. Towards the east, the Dampier Ridge rises abruptly to depths of 2750m. Here the refracted arrival from the crust is recorded at very short offset, suggesting a thin sedimentary cover on the ridge. The large offset (80km) of the triplication point between the refracted arrivals from the crust and the mantle suggests a thick crust. Further east on the MCS profile, three sub-basins are evident: the Middleton, Capel and Faust basins. Here the crust and mantle arrivals are recorded as high-amplitude first arrivals associated with a very strong PmP arrival. The offset of the triplication point between the crust and mantle refracted arrivals ranges from 40km to more than 60km. Towards the Lord Howe Platform the mantle refracted arrivals are recorded as a very low amplitude phase. Preliminary interpretation of the whole wide-angle dataset suggests that strong variations occur in the nature and the thickness of the crust. This will be confirmed by the preliminary Vp seismic velocity structure obtained from a tomographic inversion of the first-arrival traveltimes.

The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
 This Mount Peake, NT, 1995 (P646), radiometric line data, AWAGS levelled were acquired in 1995 by the NT Government, and consisted of 60332 line-kilometres of data at 500m line spacing and 100m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.
