Nature's glass artists: Volcanoes, lightning and meteorite impacts

We are all the beneficiaries of glass - from the vessels that hold our drinks, fiber optics that carry our communications, and the solar panels that convert the sun’s energy into electricity, contributing to a greener future, to name a few.  But did you know glass can also be made in nature? 
Dramatic natural events like lightning strikes, volcanic eruptions and meteorite impacts can all produce glass. We find beautiful evidence of this here on Earth…and also on the Moon!
The value of glass has been recognized with the United Nations declaring 2022 to be the International Year of Glass.  Subsequently the school student theme for Australia’s National Science Week follows suit.  Join Geoscience Australia, the ACT Education Directorate and the ANU Research School of Earth Sciences to explore forms of natural glass.

L178 Central Victoria (Stawell / Bendigo / Melbourne Zones) Seismic Transect, VIC, 2006 Stacked and Migrated Seismic data and images for line 06GA-V1, 06GA-V2, 06GA-V3, and 06GA-V4

A ~400 km long deep crustal reflection seismic survey was acquired in central Victoria, Australia, in
2006. It has provided information on crustal architecture across the western Lachlan Orogen and has
greatly added to the understanding of the tectonic evolution. The east-dipping Moyston Fault is
confirmed as the suture between the Delamerian and western Lachlan Orogens, and is shown to
extend down to the Moho. The Avoca Fault, the boundary between the Stawell and Bendigo Zones, is
a west-dipping listric reverse fault that intersects the Moyston Fault at a depth of about 22 km, forming a
V-shaped geometry. Both the Stawell and Bendigo Zones can be divided broadly into a lower crustal
region of interlayered and imbricated metavolcanic and metasedimentary rocks and an upper crustal
region of tightly folded metasedimentary rocks. The Stawell Zone was probably part of a Cambrian
accretionary system along the eastern Gondwanaland margin, and mafic rocks may have been partly
consumed by Cambrian subduction. Much of the Early Cambrian oceanic crust beneath the Bendigo
Zone was not subducted, and is preserved as a crustal-scale imbricate thrust stack. The seismic data
have shown that a thin-skinned structural model appears to be valid for much of the Melbourne Zone,
whereas the Stawell and Bendigo Zones have a thick-skinned structural style. Internal faults in the
Stawell and Bendigo Zones are mostly west-dipping listric faults, which extend from the surface to near
the base of the crust. The Heathcote Fault Zone, the boundary between the Bendigo and Melbourne
Zones, extends to at least 20 km, and possibly to the Moho. A striking feature in the seismic data is the
markedly different seismic character of the mid to lower crust of the Melbourne Zone. The deep seismic
reflection data for the Melbourne Zone have revealed a multilayered crustal structure that supports the
Selwyn Block model.

Kidson AreaB dose rate 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. The terrestrial dose rate grid is derived as a linear combination of the filtered K, U and Th grids. A low pass filter is applied to this grid to generate the filtered terrestrial dose rate grid.
This Kidson AreaB dose rate grid geodetic has a cell size of 0.00083 degrees (approximately 89m) and shows the terrestrial dose rate of the Kidson Areas A &amp; B, WA, 1996. The data used to produce this grid was acquired in 1996 by the WA Government, and consisted of 128005 line-kilometres of data at 400m line spacing and 60m terrain clearance.

Otway Basin Seismic Survey 1992: Operational Report

The Australian Geological Survey Organisation (AGSO) (formerly the Bureau of Mineral Resources, Geology and Geophysics (BMR)) conducted a deep reflection seismicprofiling survey in the onshore portion of the Otway Basin in the southeastern part of South Australia and southwestern part of Victoria, from February to June 1992. The seismic surveyformed part of a National Geoscience Mapping Accord (NGMA) project to study the early development of the Otway Basin.
The objective of the seismic survey was to acquire new deep reflection seismic data (20 seconds two way travel time) using explosive seismic energy sources to improve on the knowledge of early sedimentary sequences in the Otway Basin, especially at depths greaterthan 3 km (ie. deeper than 2 seconds on a seismic section). Explosive seismic energy sources were used in an attempt to provide a stronger seismic energy source than the seismic vibratorsources currently used in the region by seismic contractors. Eight seismic lines with a total survey line length of 474 km were planned for the seismic survey, specifically positioned totarget the survey objectives. Positioning of the seismic lines was achieved through consultation with NGMA partners, industry and universities.
The seismic survey obtained 461 km of 5 to 10 fold CMP deep reflection seismic dataalong seven of the proposed seismic lines over a 15 week acquisition period. Line 8 was deleted from the program due to Line 2 being extended in length and budgetary constraints.In addition to the seismic survey, gravity observations were made by the Geological Survey of Victoria and AGSO at 300 m intervals along all seismic lines. All seismic lines were alsoflown by the AGSO geophysical aircraft to record aeromagnetic and radiometric data at a flight height of 100 m AGL.

Great Artesian Basin 3D chronostratigraphic model: providing new insights into hydrogeological variability and connectivity

Output Type: Exploring for the Future Extended Abstract

Short Abstract: Australia's Great Artesian Basin (GAB) is a vital groundwater system extending across parts of Queensland, New South Wales, South Australia, and the Northern Territory, crucial for community water supplies, economic development, indigenous cultural values and groundwater dependent ecosystems. Managing GAB groundwater poses challenges due to the complex structure of the sedimentary basin, requiring a better understanding of aquifers, aquitards, and hydraulic connections at a whole GAB scale. Additionally, inconsistencies in nomenclature and subdivisions across the basin further complicate the definition and description of these strata. This study employs an integrated basin analysis workflow using new and existing data to create a 3D geological model tied to a consistent chronostratigraphic framework and State and Territory hydrostratigraphic classifications. The model refines the characteristics of 18 hydrogeological units, offering insights into aquifer boundaries and connectivity. This comprehensive approach enhances the 'whole-of-Basin' subsurface geological understanding, benefiting groundwater management, resource assessments, uncertainty risk assessment and environmental impact assessments across multiple jurisdictions and the broader resource sector (e.g., Carbone Capture and Storage and hydrogen).

Alteration vectors to Olympic Dam-style and Ernest Henry-style Cu-Au mineralisation in the Moonta Subdomain

Copper-gold mineralisation in the Moonta-Wallaroo district of the south-eastern Gawler Craton is associated with regionally extensive magmatism and Na-Fe-K metasomatism, typical of Fe-oxide Cu-Au mineral provinces worldwide.  In the Moonta-Wallaroo district, early widespread albite+/-actinolite+/-magnetite alteration is closely associated with magmatic fluids from granites of the Hiltaba Suite (ca. 1600 Ma) infiltrating the metasedimentary Wallaroo Group host rocks.  Zones of biotite-magnetite alteration, often in highly foliated structural zones, also formed at this time and are associated with minor Cu mineralisation.  Dating of monazite and titanite associated with magnetite-bearing alteration shows a strong temporal link with Hiltaba magmatism.  Copper mineralisation is most closely associated with later chlorite-quartz-hematite-kfeldspar veining and alteration which overprints, replaces and demagnetises the early magnetite-bearing alteration.  Latest stage alteration occurs as kaolinite-quartz and quartz-carbonate-hematite epithermal style alteration and veining, most notably along the Alford Shear Zone on the southern margin of the Tickera Granite.  This late argillic alteration is also seen as a late overprint in the Wheal Hughes mine at Moonta.  Drill targeting has historically often been of magnetic anomalies, but alteration paragenesis suggests that magnetic lows due to de-magnetising copper-bearing fluids may be better drill targets.
