Use of fibre-optic telecommunications sensing for CCS monitoring

Germán Rodríguez‐Pradilla, Tobermory Mackay-Champion, James Phillip Verdon

Areas of the UK seabed that are licensed for carbon dioxide (CO₂) storage are located close to existing subsea fibre-optic telecommunications cables. This UKCCSRC-funded project explored whether these cables could provide a cost-effective means of monitoring seismic activity around CO2 storage operations. …

Ambient Noise Tomography for District-Scale Mineral Exploration Using Nodal MEMS Accelerometers: A Case Study from the Kansanshi Cu-Au Mine, Zambia

Tobermory Mackay-Champion, Nicholas Harmon, Sekelo Mutelekesha, Mulenga Chanda et autres

Abstract Metals are essential to the success of the energy transition, but the discovery rate of deposits has been in decline. Innovative new methods of exploration are required. In recent years, Ambient Noise Tomography (ANT) using passive seismic wavefields recovered from the …

Seismic evidence for a melt-depleted lower crust and transcrustal magmatism on Mars

Tobermory Mackay-Champion, M.C. Anderson Loake, Richard M. Palin, Jon Wade et autres

Abstract The crust of Mars preserves a record of early planetary evolution in the absence of plate tectonics, offering crucial insights into the development of terrestrial planets. Seismic data from NASA’s InSight mission reveal a stratified crust with an intracrustal seismic discontinuity …

Passive seismic data from a rift tip on the Larsen C Ice Shelf, Antarctic Peninsula, November-December 2022

Aisling Dunn, John Michael Kendall, Sarah Thompson, Thomas Hudson et autres

The data are seismic time series collected by accelerometers and geophones deployed radially around a rift tip stalled in the Joerg suture zone, Larsen C Ice Shelf, Antarctic Peninsula. Data were collected November-December 2022 during the RiPIce (Rift Propagation for Ice sheet …

Origin and emplacement of the Variscan Lizard Ophiolite, and underlying thrust sheets, Cornwall, SW England

Michael Searle, George H. Willment, Tobermory Mackay-Champion, Josh T. Evans et autres

Abstract The earliest stage of the Variscan orogeny in SW England is marked by the formation and obduction of the Mid-Devonian Lizard ophiolite from the Rheic ocean northwestward onto the previously passive continental margin of Avalonia (Laurussia). The Lizard ophiolite comprises an …

A Himalayan-Scale Orogen in the Central African Copperbelt and the Formation of a World-Class Metal Province.

Tobermory Mackay-Champion

The Central African Copperbelt (CACB) of Zambia and the Democratic Republic of the Congo is the world’s largest sediment-hosted copper-cobalt province. It comprises Tonian–Ediacaran sedimentary rocks of the Katangan Basin and Ediacaran–Cambrian metamorphic and intrusive rocks formed during the assembly of Gondwana. …

An Inverse Method for Quantifying Petrological Parameters and Uncertainty in Phase Equilibrium Modelling

Tobermory Mackay-Champion, Ian P. Cawood

ABSTRACT Phase equilibrium modelling offers a powerful quantitative framework for understanding petrological processes. Yet, many studies still rely on qualitative comparisons between natural datasets and these forward modelled predictions to constrain model parameters, commonly pressure–temperature ( P – T ) conditions. Compounding …

Late Ordovician regional high-pressure metamorphism in Scotland, UK: Caledonian metamorphic climax predated the closure of the Iapetus Ocean

Thomas N. Lamont, William H. McCarthy, Rob A. Strachan, Nick M.W. Roberts et autres

Abstract We document newly recognized Late Ordovician high-pressure (HP) metamorphism in the Scottish Caledonides. Garnet growth at ca. 455–445 Ma has been previously reported from across the Northern Highland Terrane (NHT) and Shetland, yet the metamorphic conditions are unknown and the tectonic …

Late Ordovician regional high-pressure metamorphism in Scotland: Caledonian metamorphic climax predated the closure of Iapetus

Thomas N. Lamont, William H. McCarthy, Robin A. Strachan, Nick M.W. Roberts et autres

We document newly recognised Late Ordovician high-pressure (HP) metamorphism in the Scottish Caledonides. Garnet growth at ca. 455–445 Ma within metabasic rocks from the Ross of Mull is constrained to pressures >0.9 GPa and was associated with formation of kyanite-bearing assemblages in …
