Prof Alex Maltman

Profile

I joined the Department of Geology at Aberystwyth in 1973, with an Honours degree in Geology from the University of Liverpool and an MS and PhD from the University of Illinois.

My ensuing research covered a variety of subjects, such as the slates of Vermont and North Wales, geological aspects of mid-Wales, Anglesey, the Scottish Hebrides, Italian Apennines and SW Japan, but my main effort was exploring how geological sediments deform. Combining fieldwork with experimental deformation, I investigated the physical behaviour of sediments in situations such as beneath moving glaciers, in the clay linings of landfill sites, in landslips and submarine landslides, and most importantly at the mega-faults where the Earth’s tectonic plates are actively converging. Thus for over twenty years I was involved with the international Ocean Drilling Program, researching sediment cores from the plate boundaries of the north-western USA, Peru and Chile, Barbados and Japan’s Nankai Trench.

My teaching at Aberystwyth was always highly regarded but two highlights were being voted outstanding lecturer in 2012 - the first time that student-led teaching awards were held – and in 2015 when the student enrolment for my course on “Planet Earth” exceeded 600.

Throughout this time, as a hobby I grew grapevines and made wine, and became interested in the science involved. Inevitably, this led to exploring the increasingly fashionable claim that vineyard geology is paramount in the taste of a wine. As a result, and especially since retiring from the university in 2018, I have been giving talks, webinars, podcasts, etc. on the matter, and contributing to international conferences, newspaper columns, journals, magazines and books (including the World Atlas of Wine and the Oxford Companion to Wine, the two volumes most highly regarded in the wine world). My own book on the subject was published in 2018.
