A ∼400 km long deep crustal reflection seismic survey was acquired in central Victoria, Australia, 2006. It has provided information on architecture across the western Lachlan Orogen and greatly added to understanding of tectonic evolution. The east-dipping Moyston Fault is confirmed as suture between Delamerian Orogens, shown extend down Moho. Avoca Fault, boundary Stawell Bendigo Zones, a west-dipping listric reverse fault that intersects at depth about 22 km, forming V-shaped geometry....
Abstract Deformation events and episodes of metamorphic mineral growth are usually regarded as relatively local phenomena. It is not expected that specific within an orogenic sequence should exactly correlate over large distances. There no obvious reason, for example, to assume deformation and/or in the Western European Alps would directly with taking place Aegean continental crust, c. 1000 km distant. Yet linked metamorphism appear take at same time distances, even these apparently...
Geological exposures in the Lambert Rift region of East Antarctica comprise scattered coastal outcrops and inland nunataks sporadically protruding through Antarctic ice sheet from Prydz Bay to southernmost end Prince Charles Mountains. This study utilized airborne magnetic, gravity, radar data interpret distribution architecture tectonic terranes that are largely buried beneath thick sheet.

Deep seismic reflection data collected across the western Lachlan orogen of southeast Australia have provided important insights into crustal-scale fluid pathways and possible source rocks in one richest orogenic gold provinces world. The profiles span three most productive structural zones Victoria: Stawell, Bendigo, Melbourne zones. zone-scale variations age style deposits correspond with differences crustal structure composition. bilateral distribution production Stawell Bendigo is...
To promote a more efficient and transparent geochemistry data ecosystem, consortium of Australian university research laboratories called the AuScope Geochemistry Network assembled to build collaborative platform for express purpose preserving, disseminating collating geochronology isotopic data. In partnership with geoscience‐data‐solutions company Lithodat Pty Ltd, open, cloud‐based AusGeochem ( https://ausgeochem.auscope.org.au ) was developed simultaneously serve as geosample registry,...
Addressing global environmental and societal challenges requires robust, interdisciplinary data ecosystems that support collaboration across geographic, cultural, disciplinary boundaries. AuScope, Australia’s National Research Infrastructure (NRI) provider for the geoscience community, collaboratively tackles grand such as climate change, natural resource security, hazards. AuScope is funded by Australian Government’s Collaborative Strategy (NCRIS) integrates tools, data,...
In the polymetamorphic Mary Kathleen Fold Belt, at centre of Proterozoic Mount Isa Inlier, Queensland, an early phase extension (1760–1730 Ma) resulted in intrusion voluminous granitic and doleritic magmas into carbonate-evaporite-dominated Corella Formation ∼5–10 km depths. Widespread high-temperature metasomatism ensued, involving scapolitization dolerite, formation albite-scapolite shear zones granite, exo- endoskarn formation, a zone K−Na−Ca alteration lowermost Formation. Granites...
We present coupled 3D deformation – fluid-flow models which place constraints on the importance of basalt dome shape and interpreted synmineralising shortening direction in localising gold mineralisation around domes Stawell corridor, western Victoria. Gold Magdala orebody at mine occurs predominantly within a thin metasomatised unit named Facies blankets also close to parasitic fold-like lobes domes. In dome-scale that do not contain lobes, areas with maximum rates occur tops flanks where...
Gold mineralisation in the Lachlan Orogen of western Victoria, is generally hosted turbidites with very low-grade metamorphic assemblages. Metamorphic data from these are relatively rare because fine-grained nature pelitic component and lack suitable assemblages for thermobarometric estimates. In this study, 'illite crystallinity' (Kübler Index) b-lattice spacing measurements were carried out on white micas metapelites, collected near inferred margin Selwyn Block, as well three exploration...
Abstract This paper presents a new interpretation of the tectonic evolution New Caledonia, based on extrapolation detailed structural analysis at several different scales. The coherent high-pressure schist belt northern Caledonia contains clear evidence for cyclicity in orogenic process. Two switches from large-scale crustal shortening to extensional tectonism can be recognized. We propose that orogenesis initially resulted significant thickening, obduction, and (15–20 kbar) metamorphism....
Workplace occupancy detection is becoming increasingly important in large Activity Based Work (ABW) environments as it helps building and office management understand the utilisation potential benefits of shared workplace. However, existing sensor-based technologies detect workstation indoor spaces require extensive installation hardware maintenance incurring ongoing costs. Moreover, accuracy can depend on specific seating styles workers since sensors are usually placed under table or...
One of the core challenges in open-plan workspaces is to ensure a good level concentration for workers while performing their tasks. Hence, being able infer levels will allow building designers, managers, and estimate what effect different layouts have find an optimal one. In this research, we present ambient-physical system investigate inference problem. Specifically, deploy series pervasive sensors capture various ambient physical signals related perceived at work. The practicality our has...
A 150×150 km area of western Victoria has been modelled in three dimensions to a depth ∼20 km. This was constructed through integrated analysis and serial cross-sections geological geophysical datasets, utilising mapped positions major faults, intrusive bodies lithostratigraphic packages as primary inputs. These are extrapolated under cover interpretation upward continued multiscale wavelet edges aeromagnetic gravity data, inversion the field acoustic boundaries. The objective develop an...
3D models and computer-based numerical simulations have been used in the exploration industry for some time to visualise geometry mechanisms resulting formation of orebodies. However, due part computational limitations, few run on complex (real) geometries order predict location new ore systems. Presented here are results an program developed by Predictive Mineral Discovery Cooperative Research Centre (pmd*CRC) MPI (now Leviathan Resources) orogenic-gold system western Victoria that utilised...
Brutal university cuts are putting at risk an industry crucial to addressing climate change Down Under and around the world. Saving geoscience will require a community reckoning.
Variable distribution of elevated gold grades in the Magdala Central Lode system is controlled by preferential and localised reactivation pre-existing faults a progressively rotating stress field. Populations slickenline lineations on fault surfaces combination with extension vein arrays associated indicate formed initially during southwest – northeast compression, but was subsequently locally reactivated east west compression lower angle segments to produce series ore-shoots within overall...
Coal-bearing basins have increased economic potential for enhanced geothermal systems owing to thermal insulation provided by the coal and associated organic-rich sediments. In such insulation-dominated prospects, heat refraction effects with buried insulators can produce negative surface heat-flow anomalies in most prospective areas. The Latrobe Valley Victoria, Australia, is an archetypal basin. Using numerical simulations incorporating geometries, we show that coals might elevate...
The ability to effectively target ore shoots requires a clear understanding of the numerous parameters that control their formation. However, identification nature and timing these is difficult, particularly in polydeformed deposits with complex stratigraphic hydrothermal histories. For example, at Stawell gold mine’s Magdala southeastern Australia are hosted by rocks experienced least three ductile two brittle deformation events 70 m.y. prior principal mineralization event, have close...
Due to the increasing nature of flexible work and recent requirements from COVID-19 restrictions, workplaces are becoming more hybrid (i.e. allowing workers between traditional office spaces elsewhere including home). Since different in design, layout available facilities, many find it difficult adjust accordingly. Eventually, this impacts negatively towards productivity other related parameters concentration, stress, mood while at work. One key factors that causes negative experience is...
