(1985, Aberystwyth), I went on to pursue postgraduate research on the
ore-mineralogy of the Central Wales Pb-Ag-Zn-Cu mining district, in
between stints volunteering with the British Geological Survey (BGS)
and other activities. Writing the work up in the early 1990s, I was
awarded an MPhil in 1995.
Much of my geological research interest, since that time, has
focused upon the interplay between
Welsh mineral deposits and regional geological processes through time.
Through working with BGS and with the commercial sector on gold
deposits in the Highlands of Scotland, I soon appreciated the
importance of approaching mineral deposits in a multidisciplinary
manner. Such an approach has proved useful ever since. In recent
years I have been involved, among other things, in a reappraisal
of intrusive igneous rocks associated with the early Ordovician Rhobell
Volcanism of North Wales - the rocks are slightly to horribly
altered and mineralised, but we are making good progress!
Central Wales, it turned out, proved to be a far more
orefield than the literature suggested, 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
relationship between mineralisation and deformation has major
connotations in terms of a region's crustal evolution, so it is of
particular interest to me, originally encouraged by my discovery in
1997 that the gold-bearing veins of the Dolgellau Gold-belt
pre-date the regional, mid-Devonian Acadian deformation. The veins had
for many decades been assumed to post-date that deformation. Click here
