Why Does the Broken Hill Deposit Sit in Resistive Crust? Magnetotelluric Evidence for Metamorphic Decoupling of a World‐Class Mineral System

by
Regional gravity and magnetic anomaly maps showing tectonic boundaries and the location of the Broken Hill deposit, NSW, Australia.

Researchers used magnetotelluric surveys to image the electrical structure of the crust around the world-class Broken Hill Pb-Zn-Ag deposit in NSW, Australia. They found that the upper crust here is mostly resistive, with only small, isolated conductive zones linked to the ore body and its host rocks, which do not connect down to a deeper … Read more…

Rainfall and tectonic forcing lead to contrasting headwater slope evolutions

by

Landscapes evolve through the coupled effects of tectonics and surface processes. Previous studies have shown that uplift rate changes generate upstream-migrating erosion waves, altering downstream slopes while upstream slopes remain constant until the wave arrives. However, the distinctive differences between landscape responses to uplift versus climatic changes, particularly rainfall rate changes, remain incompletely described. This … Read more…

Strain controls the electrical conductivity distribution in the lithosphere

by

Magnetotellurics (MT) utilize measurements of electromagnetic fields at Earth’s surface to image the electrical conductivity distribution at depths from a few meters to ∼200 km. MT is especially powerful for mapping mineralized fluid pathways, as it is sensitive to inter- connected minor conductive phases such as fluids, melts, or sulfides. However, conductivity anomalies documented by … Read more…

The role of asthenospheric flow during rift propagation and breakup

by

Abstract Continental rifting precedes the breakup of continents, leading to the formation of passive margins and oceanic lithosphere. Although rifting dynamics is classically described in terms of either active rifting caused by active mantle upwelling, or passive rifting caused by far-field extensional stresses, it was proposed that a transition from passive to active rifting can … Read more…

Basin GENESIS Hub opening group photo 19 August 2015The ARC Research Hub for Basin Geodynamics and Evolution of Sedimentary Systems (Basin GENESIS Hub) opened today at a reception held in the Charles Perkins Centre at the University of Sydney. The launch as attended by representatives from Universities, industry, Geoscience Australia, the ARC, the NCI and the Office of the NSW Chief Scientist and Engineer.

The Basin GENESIS Hub will use computer modelling to fine-tune our understanding of the nation’s sedimentary basins, which hold many of the natural resources we use in day-to-day life.

The research will be of fundamental importance to the geo-software industry used by exploration and mining companies, explains Hub Director Professor Dietmar Müller from the University of Sydney.  … Read more…
