GSNSW Exploration NSW Area V Northern Moree potassium grid geodetic

The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium (K), uranium (U) and thorium (Th). 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 radiometric potassium grid has a cell size of 0.00077 degrees (approximately 80m) and shows potassium element concentration of the NSW DMR, Discovery 2000, Area V, Northern Moree, NSW in units of percent (or %). The data used to produce this grid was acquired in 2001 by the NSW Government, and consisted of 28696 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.

Rupture Characteristics and the Structural Control of the 2016 Mwp 6.1 Intraplate Earthquake in the Petermann Ranges, Australia

The 20 May 2016 surface-rupturing intraplate earthquake in the Petermann Ranges is the largest onshore earthquake to occur in the Australian continent in 19 yr. We use in situ and Interferometric Synthetic Aperture Radar surface observations, aftershock distribution, and the fitting of P-wave source spectra to determine source properties of the Petermann earthquake. Surface observations reveal a 21-km-long surface rupture trace (strike = 294°±29°) with heterogeneous vertical displacements ( &lt;0:1–0:96 m). Aftershock arrays suggest a triangular-shaped rupture plane (dip ≈ 30°) that intersects the subsurface projection of the major geophysical structure (Woodroffe thrust [WT]) proximal to the preferred location of the mainshock hypocenter, suggesting the mainshock nucleated at a fault junction. Footwall seismicity includes apparent southwest-dipping Riedel-type alignments, including possible activation of the deep segment of the WT. We estimate a moment magnitude (Mw) of 6.0 and a corner frequency (fc) of 0.2 Hz, respectively, from spectral fitting of source spectra in the 0.02–2 Hz frequency band. These translate into a fault area of 124 km2 and an average slip of 0.36 m. The estimated stress drop of 2.2 MPa is low for an intraplate earthquake; we attribute this to low-frictional slip (effective coefficient of friction &gt;0:015) along rupture-parallel phyllosilicate-rich surfaces within the host rock fabric with possible additional contributions from elevated pore-fluid pressures.

Galilee Ellipsoid Height geodetic

Digital Elevation data record the terrain height variations from the processed point-located data recorded during a geophysical survey. This Galilee Ellipsoid Height geodetic is elevation data for the Galilee Gravity Survey (P201040). This survey was acquired under the project No. 201040 for the geological survey of QLD. The grid has a cell size of 0.007 degrees (approximately 748m).  This grid contains the ground elevation relative to the ellipsoid for the Galilee Gravity Survey (P201040). It represents the vertical distance from a location on the Earth's surface to the ellipsoid. The data are given in units of meters. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.

The Paleoproterozoic McArthur River (HYC) Pb/Zn/Ag deposit of northern Australia: Organic geochemistry and ore genesis

Polycyclic aromatic hydrocarbons (PAH) in ore and mudstone within the McArthur River ore deposit show compound distributions similar to those of hydrothermally-generated petroleum in the Guaymas Basin and significantly different from those found in conventional oil (Chen et al., submitted).  PAH abundances and isomer distribution also reflect a temperature gradient between the source of mineralising fluids and the sediments fringing the ore system during ore formation.  Along with other geochemical, geological and mineralogical lines of evidence, these data provide strong evidence that the ore formed in a ?diagenetic? environment under marine conditions. Given that the McArthur River orebody is an exquisitely preserved example of a sediment-hosted base metal deposit, these results may be widely applicable.  Organic geochemistry can make significant contributions to understanding processes of ore deposition.   The distribution of PAHs suggests that they were generated at temperatures between 250-400?C (Simoneit, pers. comm 2001), in contrast to previous estimates of 150-250?C.  This has new and significant implications for ore formation and exploration models.  The higher temperature estimates for ore forming brines require a deeper metal source within the basin, and fluid volumes may have been lower because metal carrying capacity increases with temperature. Importantly, at higher temperatures hydrogen sulfide can be transported with the metal ions, indicating that evaporites are not required as a source of sulfur.  The McArthur deposit is also a rich repository of paleobiological information, allowing studies of the microbiology of ore formation and the paleobiology of an ancient hydrothermal system (Logan et al., 2001).

A Rb-Sr geochronological study in the Proterozoic Tennant Creek Block, central Australia

Rb-Sr isotopic data from total rock and mineral samples provide a broader geochronological framework than has hitherto been available for the Proterozoic rocks of the Tennant Creek Block. The oldest documented event is the amphibolite-facies metamorphism at 1920 Â± 60 m.y. of possible basement rocks from the BMR 3 area, to the west-southwest of Tennant Creek township. The lower grade metamorphic rocks of the Warramunga Group were deposited before the major deformation episode which is inferred to have occurred at about 1810 m.y. Certain of the units within the Warramunga Group, of which the Bernborough Volcanics are an example; underwent isotopic resetting of total-rock systems during subsequent deformation. Granite ages range from 1797 m.y. for a phase of the Tennant Creek Granite to less than 1500 m.y. for the Cabbage Gum and Gosse River East Granites. Dated lamprophyre and porphyry samples yield ages of about 1660 m.y. and 1760 m.y., respectively. Muscovite separates from the Juno, Warrego, Golden Forty, and Nobles Nob mines suggest a common origin for the ore deposits about 1810 m.y. ago.
