Geological mapping of British Antarctic Territory
A project to compile over 50 years of geological field data into new geological maps has already seen the publication of six new sheets.
Specialising in the interplay between global tectonics and the growth of continents, I worked at BAS as a field geologist researching the tectonic history of the Antarctic Peninsula and the origin of its magmatic events. This work continues on the Lassiter Coast of the Antarctica, looking into how crustal deformation led to the emplacement of thousands of kilometres of new granitic crust. My work uses a combination of geochemistry, magnetic fabric analysis, and field data, which I have applied in Antarctica, SE Asia, and New Zealand, looking at how these processes change around the Pacific margin. Beyond tectonic-magmatic relations, my work covers a diverse range of geological science. This includes working on Antarctic geothermal heat flow; satellite remote sensing of exposed rocks and volcanoes; and the large-scale tectonic histories of the Pacific margin.

GeoMAP Antarctica, an open-access and comprehensive geological mapping database of Antarctica, was released today in Nature Scientific Data. Understanding Antarctica’s geosphere is, and has been, critical for understanding the continent’s […]
A team of scientists has discovered a rare lava lake on a remote and inaccessible sub-Antarctic island. This volcano in the South Sandwich Islands is only the 8th to be identified worldwide to have a persistent lava lake.
This paper revised the geological history of the Antarctic Peninsula to show how it developed over the last 500 million years, and used this history to tell us about the […]
