A native of Glasgow, Iain McDonald took his undergraduate degree at the University of Glasgow. In addition to the obvious subject specific skills, the BSc Chemistry & Geology course in the late 1980's provided invaluable "hands-on" training in the kinds of applied analytical chemistry, instrument development and inspired bodging that has long since disappeared from most undergraduate courses. In 1990, Iain moved to South Africa to begin a PhD on PGE geochemistry with Maarten de Wit at the University of Cape Town. Unfortunately the laboratory where most of the work was to be carried out was 700 miles away in Johannesburg so Iain moved north to the City of Gold. He found a lab and a long term home among the various geologists, nuclear and solid state physicists, chemists and engineers in the Schonland Research Centre for Nuclear Sciences (now iThemba Labs) at the University of the Witwatersrand. Over the course of his PhD, Iain developed improved fire-assay methods for PGE analysis, was involved in the characterisation of a new low-level PGE standard reference material and showed in a series of experiments that the presence of carbon, and particularly carbon monoxide, in melts could lead to volatilisation of all the PGE

In 1993, Iain returned to the UK to a postdoc at Manchester University working with David Vaughan and Grenville Turner. The project formed part of a larger EU funded project to evaluate new types of Pt and Pd mineralisation in Madagascar and Albania. After three years in Manchester, Iain took up a lectureship in Geochemistry at the University of Greenwich in 1996. Over the next five years he set up a laboratory for routine PGE analysis and began a sustained programme of research into PGE geochemistry at impact craters collaborating with colleagues in Austria, Denmark, South Africa and America. These studies involved searching for extraterrestrial PGE in impact melt sheets and breccias at Morokweng (South Africa), Ries (Germany), Chesapeake Bay (America) and Zhamanshin (Russia) and for traces of the Late Heavy Bombardment recorded in metasediments at Isua in Greenland.

Since moving to Cardiff in 2001, Iain played a major role in the design and commissioning of the Elemental Analysis Laboratory in 2002 and subsequent upgrades in 2009 and 2017. This includes the only PGE lab in the UK to focus on impact crater research - and expanded his research to cover meteorites as well as craters. Major highlights of this research has been the discovery of a boulder sized fragment of the asteroid that formed the 144 million year old Morokweng impact crater in South Africa (published in Nature in May 2006) and the discovery of a very young crater under the Hiawatha glacier in northern Greenland (publushed in Science Advances in 2018).

The other major area of research that Iain has led since moving to Cardiff is a re-evaluation of the PGE mineralization in the northern limb of the Bushveld Complex in South Africa. This limb hosts the enigmatic Platreef Ni-Cu-PGE deposit and its relationships with the rest of the Bushveld Complex are not clear. This research has revolutionised ideas about the Platreef, its relationship with the Merensky Reef, and the manner in which magmas were intruded into the northern limb. This has led to completely new genetic models for this style of deposit and research grants funded by industry and NERC.

Editorial roles

Since 2001, Iain has organised or co-organised two conferences. First, an International Workshop on "21st Century Pt-Pd Deposits" at Southampton University in conjunction with H.M. Prichard and A.G. Gunn. A fully peer-reviewed and edited volume of papers from this appeared in volume 111 (1) of Applied Earth Science (Trans Inst. Min. Metall. Section B) in 2002.

The second was the 3 day Geological Society Fermor Flagship Meeting on "World Class Mineral Deposits & Earth Evolution" at Cardiff University in 2003. Peer-reviewed papers from this were published in a special volume of Mineralium Deposita (volume 40 (6) edited by Adrian Boyce and Iain McDonald) and in a special publication of the Geological Society (Number 248, Mineral Deposits and Earth Evolution; edited by McDonald, Boyce, Butler, Herrington and Polya) in 2005.

Also in 2005, Iain co-edited volume 114 (4) of Applied Earth Science (Trans Inst. Min. Metall. Section B), a special issue on minerlization in the northern limb of the Bushveld Complex, with Judith Kinnaird from the University of the Witwatersrand.

From 2001-2017 he served on the editorial board of Applied Earth Science (Trans Inst. Min. Metall. Section B), including serving as Executive Editor from 2005-2009.
