GSNSW Eromanga-Thompson magnetic first vd grid geodetic

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data 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 GSNSW Eromanga-Thompson magnetic first vd grid geodetic is a first vertical derivative of the Total Magnetic Intensity grid for the Eromanga - Thomson Airborne Survey, NSW, 2005.
This grid has a cell size of 0.00077 degrees (approximately 80m). The grid has units of nanoTesla per km (or nT/km). The data used to produce the TMI grid was acquired in 2005 by the NSW Government, and consisted of 166533 line-kilometres of data at a line spacing between 250m and 400m, and 60m terrain clearance. A Fast Fourier Transform (FFT) process was applied to the original grid to calculate the first vertical derivative grid.

Palaeontological evidence for the Early Cambrian age of the Bukalara Sandstone, McArthur Basin, NT

The Bukalara sandstone overlies the Proterozoic rocks of the McArthur Basin, Northern Territory. Trace fossils are present in it at 5 localities on the Mount Young 1:250 000 Sheet: they include Skolithos, a probable Chamiodiscus Ford 1958, and possibly the Annelid Dickinsonia Glaessner 1966. The trace fossils support the tentative Early Cambrian age suggested earlier for the Bukalara Sandstone.

Leg 189 Synthesis: Cretaceous-Holocene History of the Tasmanian Gateway

Ocean Drilling Program (ODP) Leg 189 drilled five sites in bathyal depths on submerged continental blocks in the Tasmanian Gateway, to help refine the hypothesis that its opening near the Eocene/Oligocene boundary led to formation of the Antarctic Circumpolar Current (ACC), progressive thermal isolation of Antarctica, climatic cooling, and development of an Antarctic ice sheet. In all, 4539 m of marine and largely continuous upper Maastrichtian to Holocene core were recovered, with a recovery rate of 89%. The sedimentary sequence broadly consists of shallow marine mudstones until the late Eocene, glauconitic siltstones during the late Eocene, and pelagic carbonates thereafter. The microfossils in the mudstones and siltstones are largely palynomorphs and diatoms, and those in the carbonates are largely nannofossils and foraminifers.
During the Late Cretaceous, northward movement of Australia away from Antarctica commenced, forming the Australo-Antarctic Gulf (AAG). However, a Tasmanian land bridge at 70?-65?S almost completely blocked the eastern end of the widening AAG until the late Eocene, there being no evidence of extensive current circulation across the ridge until the earliest Oligocene. Prior to the Oligocene, muddy marine siliciclastic sediments were deposited in temperate seas. During the late Eocene, the northeastern AAG was warmer and less ventilated than the gradually widening southwest sector of the Pacific Ocean, which was affected by a cool, northwesterly flowing boundary current ? a difference that may have existed since the Maastrichtian. In the late Eocene (~37 Ma), the Tasmanian land bridge and its broad shelves began to subside, currents swept the still-shallow offshore areas, and condensed glauconitic siltstones were deposited. Palynological and diatom evidence suggest a general cooling. The southwestern South Tasman Rise finally separated from Antarctica at the time of the Eocene/Oligocene boundary (~33.5 Ma), the rise subsided, and the continental margin of Tasmania collapsed. The Tasmanian Gateway opened to deep water, disrupting oceanic circulation at high southern latitudes, and leading to one of the major climatic shifts of the Cenozoic.
Thereafter, a marked reduction in siliciclastic supply, and the flow of warm currents from northern latitudes, favored the deposition of carbonate. At the eastern sites, deposition of Oligocene bathyal carbonates directly followed an unconformity caused by the onset of the ACC, but change was more gradual in the west. In contrast, siliceous biogenic sediments typified the Antarctic margin, now isolated from warm water by the ACC. Steady northward movement kept the Tasmanian region north of the Polar Front throughout the Neogene, and pelagic carbonates accumulated.

South Australian Exploration Initiative, Area - C4, SA, 1995 (P833), magnetic line data, AWAGS levelled

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data 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.
 These line dataset from the South Australian Exploration Initiative, Area - C4, SA, 1995 survey were acquired in 1995 by the SA Government, and consisted of 23390 line-kilometres of data at 400m line spacing and 80m 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.

Cretaceous ammonites from south-central Papua New Guinea

Eleven ammonite species, including one new taxon, are described from eleven localities in the south-central Papua New Guinea. One of them, Fauriella boissieri (Pictet), is a member of the Berriasian Tethyan fauna extended to peri-Gondwana.  Three large, but fragmentary, ammonites are identified as Puzosia aff. mayoriana (dOrbigny) and Pachydesmoceras sp. B and C, suggesting a Cenomanian age.  Acanthoceras rhotomagense (Brongniart), Calycoceras (Newboldiceras) asiaticum (Jimbo), and Cunningtoniceras cunningtoni (Sharpe) indicate more distinctly the Cenomanian age. C. cunningtoni is associated with Desmoceras (Pseudouhligella) aff. ezoanum Matsumoto, both occurring in generally the same area as the type locality of Chimbuites sinuosocostatus (Casey and Glaessner). From another locality a new species, Chimbuites giganteus is described.  Chimbuites is regarded as an offshoot of Eopachydiscus, and therefore a member of Pachydiscidae rather than Hoplitidae.  A well-preserved specimen of Romaniceras deverianum (dOrbigny) indicates a Turonian age.
