Southern McArthur Basin Gravity p201381 Spherical Cap Bouguer

Gravity data measure small changes in gravity due to changes in the density of rocks beneath the Earth's surface. 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 Southern McArthur Basin Gravity p201381 Spherical Cap Bouguer is a complete Bouguer anomaly grid for the Southern McArthur Basin Gravity Survey 2013 (P201381) survey. This gravity survey was acquired under the project No. 201381 for the geological survey of NT. The grid has a cell size of 0.00735 degrees (approximately 800m). The data are given in units of um/s^2, also known as 'gravity units', or gu. A total of 6278 gravity stations were acquired to produce this grid.

Canning Basin Project

The main aim of the Canning Basin project is to improve our understanding of the stratigraphic and structural evolution of the basin as a basis for more effective and efficient resource exploration. The first stage of the project involved studies on two contrasting scales; a basin-wide compilation of structural information (not reported here), and a detailed study of the stratigraphic architecture and evolution of the outer portion of the central part of the Lennard Shelf, some of which is presented here. The basic information generated in the Lennard Shelf study has been compiled into three folios: 1) a Well Folio containing sequence interpretations of the more important wells in the area; 2) a Seismic Folio containing sequence interpretations of seismic lines; and 3) a Map Folio containing structure
contour and isopach maps. These explanatory notes accompany the Seismic and Map Folios. More detailed discussions of the interpretations of the Devonian-Carboniferous sequences are presented in Jackson Sr others, (1992); Kennard SE others, (1992) and Southgate St others, (1993).

Bairnsdale, VIC, 1975/76 (P419), 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 Bairnsdale, VIC, 1975/76 survey were acquired in 1975 by the VIC Government, and consisted of 9638 line-kilometres of data at 1500m line spacing and 1680m 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.

Darwin Harbour Habitat Mapping Program: Probability of occurrence of filter feeders habitat

This resource contains a probability of occurrence grid of filter feeders for the greater Darwin Harbour region as part of a baseline seabed mapping program of Darwin Harbour and Bynoe Harbour. This project was funded through offset funds provided by an INPEX-led Ichthys LNG Project to the Northern Territory Government’s Department of Environment and Natural Resources (NTG-DENR) with co-investment from Geoscience Australia (GA) and the Australian Institute of Marine Science (AIMS). The intent of this program is to improve knowledge of the marine environments in the Darwin and Bynoe Harbour regions by collating and collecting baseline data that enable the creation of thematic habitat maps and information to underpin marine resource management decisions. The probability of occurrence grid of filter feeders was derived from a compilation of multiple surveys undertaken by GA, AIMS and NTG-DENR between 2011 and 2017, including GA0333 (Siwabessy et al., 2015), GA0341 (Siwabessy et al., 2015), GA0351/SOL6187 (Siwabessy et al., 2016), GA4452/SOL6432 (Siwabessy et al., 2017), GA0356 (Radke et al., 2017), and GA0358 and GA0359 (Radke et al., 2018), adding to those from a previous survey GA0333 collected by GA, AIMS and NTG-DENR.

Revised Late Cambrian (pre-Payntonian-Datsonian) conodont biostratigraphy at Black Mountain, Georgina Basin, western Queensland, Australia

Examination of new Late Cambrian samples from the upper part of the Chatsworth Limestone and lower part of the Ninmaroo Formation from Black Mountain, Georgina Basin, western Queensland (representing the pre-Payntonian, Payntonian and Datsonian Stages) has delineated five conodont assemblages in an interval that had previously not been subdivided using conodonts. Examination of the conodont fauna unambiguously confirms that the entire Payntonian Stage is of Cambrian age, as earlier indicated by the trilobite fauna, and provides three conodont assemblages that may subsequently form the basis for a conodont zonation. The Datsonian Stage, defined by the FAD of the Cordylodus proavus conodont assemblage and previously considered to equate with the Early Tremadoc (= Early Ordovician) of Europe, is now considered to represent the terminal Cambrian stage in northern Australia. The base of the Ordovician, equated with the base of Tremadoc correlatives, lies close to the Datsonian/Warendian boundary on the Black Mountain section. Two new conodont genera, Eodentatus and Hispidodontus, are established, along with four new species, E. bicuspatus, H. resimus, H. appressus and H. discretus. All are found in the Payntonian Stage in the upper part of the Chatsworth Limestone or the lower part of the Ninmaroo Formation.

The Cadell Fault, southeastern Australia: a record of temporally clustered morphogenic seismicity in a low-strain intraplate region

The Cadell Fault, found in stable continental region (SCR) crust in southeastern Australia, provides a record of temporally clustered morphogenic earthquakes spanning much of the Cenozoic. The slip rate, averaged over perhaps as many as five complete seismic cycles in the period 70–20 ka, is c. 0.4–0.5 mm/a, compared with an average rate of c. 0.005–0.01 mm/a over the period spanning the late Miocene to Recent. If full length rupture of the 80 km long feature is assumed, the average recurrence for Mw 7.3–7.5 earthquake events on the Cadell Fault in the period 70–20 ka is c. 8 kyr. About 20 kyr, representing more than two average seismic cycles, have lapsed since the most recent morphogenic seismic event on the fault. It might therefore be speculated that this fault has relapsed into a quiescent period. Episodic rupture behaviour on the Cadell Fault, and nearby faults in Phanerozoic SCR crust in eastern Australia, might be controlled by their linkage into major crustal fault systems at depth, in apparent contrast with the style of deformation in non-extended Precambrian SCR crust. Periods of strain localization on these major crustal fault systems, effectively turning deforming regions ‘on’ and ‘off’, might be influenced by changes in distant plate boundary forces. If proved, this would have profound consequences for how the occurrence of large earthquakes is assessed in Australia, as the fundamental assumption of morphogenic earthquakes occurring as a result of the progressive build-up of strain, and thus being in some way predictable in their periodicity, is not satisfied. Documenting such fault behaviour in SCR crust assists in conceptualizing the points critical to understanding the hazards posed by SCR faults worldwide.

Tsunami Animation - Landslide Generation

Landslides can happen on the seafloor, just like on land. Areas of the seafloor that are steep and loaded with sediment are more prone to undersea landslides, such as the edge of the continental slope.
When an undersea landslide occurs (perhaps after a nearby earthquake) a large mass of sand, mud and gravel can move down the slope. This movement will draw the water down and may cause a tsunami that will travel across the ocean.
