Frances Cooper

Alison Rust

Steve Sparks

Jon works on the generation, movement, and evolution of magma. He combines igneous petrology, experimental geochemistry, thermodynamics, and field geology to address the fundamental problem of how volcanoes work. Of particular interest are processes associated with magmatism at destructive plate boundaries, which host many of the world’s largest PCDs.

Frances studies the mechanics of large-scale continental deformation and the evolution of orogenic systems. She uses a multidisciplinary approach that combines field work, structural geology, igneous petrology, geochronology, thermochronology, and satellite remote sensing to investigate the relationship between tectonics, geomorphology, and copper mineralisation.

Richard Brooker

Research Associates

Alison studies the dynamics of volcanic processes using a combination of laboratory experiments, theoretical fluid mechanics, fieldwork, and petrology. Alison works with geoscientists, mathematicians, and engineers to explore connections between environmental, geophysical, and industrial issues.

Steve investigates geological processes using field studies, laboratory experiments, analytical studies, and theoretical modelling. He focuses on volcanic and igneous processes, but has also worked on fluid mechanics and sedimentology. Steve’s applied research includes risk assessment for environmental and natural hazards, nuclear waste disposal, and mining.

Laura Evenstar

Laura’s interests include sedimentology, geomorphology, and cosmogenic nuclide dating. For her PhD, Laura dated preserved paleosurfaces in northern Chile to constrain Cenozoic climate and tectonics. Laura is continuing this work at Bristol to understand how landscape evolution and chronostratigraphy in the Chilean Andes relate to the formation of PCDs.

Donny Hutton

Donny is a field geologist who works on understanding the structural controls on magmatism and mineralisation. As part of the Bristol PCD team, Donny is focusing on mapping pre-, syn-, and post-copper mineralisation structures around the Cerro Colorado mine in northern Chile.

Lia Ituarte

Lia is a field and exploration geologist who has worked in northern Chile for 5 years. She has industry experience in different copper mines and greenfield and brownfield exploration projects. As part of the Bristol PCD team, Lia is focused on bringing a mining perspective to the group and facilitating knowledge transfer between academic and industry partners. She is also working on a PCD MSc project with Jon Blundy and Alison Rust.

Brian Tattich

Brian’s interests focus on how magmatic volatile phases remove ore metals from arc magmas. PCD formation relies on high-efficiency removal of disperse ore metals from arc magmas by exsolving magmatic gases. High-T experiments on magmatic systems can identify the effects of ƒO2, ƒS2, ƒCO2, T, and P and elucidate how they affect the likelihood of forming ore deposits.

Cyril Chell-Michou

Cyril combines field studies, igneous and experimental petrology, high-precision geochronology, geochemistry and numerical modelling to uncover the processes that favour or inhibit the formation of magmatic-hydrothermal ore deposits. He is particularly interested in uncovering the factors that control the size of PCDs. At Bristol, he is developing new mineral geobarometers for granitic rocks and alteration zones typical of PCDs.
