I graduated in geology
in 1985 at Aberystwyth and went on to pursue postgraduate research leading to the award of an MPhil in 1995.
Through a long-standing interest in mineralogy and ore deposits I have
focussed much of my geological research towards the interplay between
Welsh mineral deposits and regional geological processes through time, an interest that continues to this day.
a distraction to the postgraduate studies, I was trained in mineral
exploration as a voluntary worker with the British Geological Survey
and then spent time in the commercial world on a gold exploration
project in the Scottish Dalradian, where a significant swarm of narrow
but high-grade auriferous veins was assessed. In the 2000s, I
periodically worked in the Dolgellau Gold-belt, North Wales, where
determining the unusually complex geological
controls on the occurrence of high-grade gold-shoots is the key to
Much of my academic
research through the
1980s and 90s was into the metalliferous mineralisation of the old
lead-mining district of Central Wales, an area now recognised as a
orefield, in which multiple phases of mineralisation involving not only
Pb and Zn but also more exotic elements like Co, Ni and Sb have
occurred. Please click here for
details. By the mid-1990s I had started to
examine mineral deposits throughout Wales in conjunction with the Minescan project (please
see the Conservation section for details). Such research involves
followed up by laboratory investigations and the information generated
is not only of academic importance; it has applications in many issues
surrounding metal-mining, from economic through to environmental.
One of my key research interests is in
the relationship between mineralisation and deformation. This led in
1997 to my discovery that the gold-bearing veins of the Dolgellau area
pre-date the regional Acadian deformation - they were for many years
believed to post-date it. Click here
