Iron oxide copper-gold (IOCG) deposits are consequences of lithospheric- to deposit-scale earth processes, and form where there was a coincidence ore-forming processes in space time. Building on previous conceptualisations we view 'mineral system' as an geological system which four components required have operated efficiently coincidentally, namely: (1) available sources ore metals (i.e., copper, gold, uranium, rare-earth elements) hydrothermal fluids; (2) energy drive fluids the system;...
The footprint of a mineral system is potentially detectable at range scales and lithospheric depths, reflecting the size distribution its components. Magnetotellurics one few techniques that can provide multiscale data sets to image understand systems. We have used long-period from Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) as first-order reconnaissance survey resolve large-scale architecture for mapping areas potential in northern Australia. 3-D resistivity model...
Abstract Orogenic gold deposits provide a significant source of the world’s and form along faults over wide range crustal depths spanning sub-greenschist to granulite grade faces, but remains poorly understood. In this paper we compiled thirty years long-period magnetotelluric (MT) geomagnetic depth sounding (GDS) data across western Victoria south-eastern South Australia that have sensitivity electrical resistivity crust mantle, which in turn depend on past thermal fluid processes. This...
Abstract The North Australian Zinc Belt is the largest zinc-lead province in world, containing three of ten known individual deposits (HYC, Hilton-George Fisher, and Mount Isa). Northern Cordillera America second province, a further two world’s top (Red Dog Howards Pass). Despite this world-class endowment, exploration both mineral provinces during past 2 decades has not been particularly successful, yielding only significant discoveries (Teena, Australia, Boundary, Canada). One most...
We present a resistivity model of the southern Tasmanides southeastern Australia using Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) data. Modelled lower crustal conductivity anomalies resemble concentric geometries revealed in upper crust by potential field and passive seismic These are key part architecture predicted Lachlan Orocline for evolution Tasmanides, which Proterozoic Selwyn Block drives oroclinal rotation against eastern Gondwana margin during Silurian...
The clean energy transition will require a vast increase in metal supply, yet new mineral deposit discoveries are declining, due part to challenges associated with exploring under sedimentary and volcanic cover. Recently, several case studies have demonstrated links between lithospheric electrical conductors imaged using magnetotelluric (MT) data deposits, notably Iron Oxide Copper Gold (IOCG). Adoption of MT methods for exploration is therefore growing but the general applicability...
Abstract The Mount Isa Province in northern Australia is one of the world's most strongly endowed regions for base metals and host to major iron–oxide–copper–gold (IOCG) deposits. Carpentaria conductivity anomaly at eastern margin province a electrical structure Australian continent. We use magnetotelluric data image crustal architecture this highly mineralized region. resistivity models reveal number prominent crustal‐scale conductors, suggesting that likely caused by series isolated or...
Fracture characteristics of concrete remains a focal point current research. Traditional experimental approaches and finite element simulations face limitations in the study concrete's fracture behavior. The novel combined finite-discrete method (FDEM) offers pronounced advantages for investigating at mesoscopic scale. In this paper, utilizing FDEM approach, mesoscale model encompassing aggregates, mortar, interfacial transition zone was constructed. Three-point bending on beams with precast...
We have applied a Bayesian inference algorithm and released open-source code for the 1D inversion of audio-frequency magnetotelluric data. The uses trans-dimensional Markov chain Monte Carlo technique to solve probabilistic resistivity-depth model. employs multiple chains generate an ensemble millions resistivity models that adequately fit data given assigned noise levels. aspect means number layers in model is solved rather than being predetermined. scheme favours parsimonious solution...
The characterisation of the thickness and geology cover sequences significantly improves targeting for mineral exploration in buried terrains. Audio-frequency Magnetotelluric (AMT) data is applicable to characterise sequences, where their conductivity (inverse resistivity) can be differentiated. We present a regional study from under-cover East Tennant region Northern Territory (Australia) we have applied deterministic probabilistic inversion methods derive 2D 1D resistivity models....

Abstract Geomagnetic storms can cause power grid instabilities and blackouts due to excessive geomagnetically induced currents (GICs) flowing in electric transmission systems. In this study, we assess regional vulnerability GICs by modeling the geoelectric fields significant historic geomagnetic disturbance events presence of 3D subsurface geology using data from Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) magnetotelluric array, Australia‐Wide Array Stations...
The Australian Lithospheric Architecture Magnetotelluric Program (AusLAMP) is a multi-year collaborative project aimed at resolving the first order electrical structure of continental lithosphere through acquisition long-period magnetotelluric data -55x55 km spacing. Here we present results deployment AusLAMP which was in Victoria 2014. Previous MT coverage over comprised limited 2D profiles western portion State.

A geomagnetic storm, also known as a disturbance (GMD), is major of the Earth's magnetic field caused by solar activity. storm induces electric currents in Earth that feed into power lines through substation neutral earthing, causing instabilities and even blackouts electricity transmission systems. The intensity geomagnetically induced (GICs) closely associated with electrical conductivity surrounding geology. In this paper, we analyse one most well-known storms, 1989 "Québec storm" 688...
The magnetotelluric (MT) method is becoming more widely used in the geoscience community as it becomes increasingly recognised a useful exploration tool. However, while analysis and inversion tools available to MT have increased over recent years, software work with these still somewhat limited often costly comparison some of mature techniques like gravity, magnetics seismic.The MTpy python library open source that aims assist practitioners carrying out processing steps need be carried data...
