research interests centre around the integrated use of stable
isotope geochemistry and petrology to understand regional geological
problems and tectonic environments. Examples of projects that
I am working on include:
magmatism associated with large igneous provinces with reference
to the Parana/Etendeka and Karoo provinces
between fluid flow and fault development with application
to both thrust and extensional detachment faults
Flow in high-pressure environments and its implications
for trace element recycling in subduction zones
am also working on aspects of groundwater management in the
Naukluft region of Namibia and using various isotopes to constrain
climate change impacts on groundwater systems in arid environments,
particularly through the combined use of O, C, H, N and C14
Terrane Amalgamation in Northern Mozambique and its Implications
for Gondwana AssemblyProject

assembly and dispersal of the supercontinent Gondwana constitute
two of the principle geological events that have defined
much of the tectonostratigraphic architecture of Africa,
Australia, Antarctica, Madagascar, South America and India.
How these events unfolded is central to our understanding
of geological, biological and human evolution of these regions.
In the geological context, geophysics in combination with
field-based studies of the remains of major Neoproterozoic
orogenic belts as well as volcanosedimentary successions
in Phanerozoic basins have allowed high confidence reconstructions
of the geometric fit of Gondwana components prior to the
onset of rifting and continental breakup. In contrast, there
is continued debate with respect to our understanding of
the spatial and temporal development of the continental
suture zones that lead to the formation of Gondwana. Detailed
studies of the transport direction, timing of exhumation,
P-T conditions and related magmatism of these thrusting
events have the potential to greatly assist in unravelling
the geological evolution of important Gondwana suture zones,
particularly with respect to the amalgamation of the different
crustal blocks that make up the African continent.
N-S trending, continental-scale Pan-African Mozambique Belt
extends along most of the eastern seaboard of the African
continent and represents the locus of Himalayan-style mega
arc-continent and continent-continent collisions during
the closure of the Mozambique Ocean related to the formation
of Gondwana. Much of our understanding of the Mozambique
Belt is derived from extensive studies of outcrops located
in Tanzania, Ethiopia, and Egypt. In contrast, northern
Mozambique has received little attention and yet occupies
a keystone position at the intersection of the Mozambique
Belt with other Pan-African orogens in central Africa, Antarctica
and Sri Lanka (ie the Zambezi Belt, Maudheim Belt, etc).
This problem has recently been addressed through a large-scale
field and geophysical mapping program, completed by the
geological surveys of South Africa, Norway, Finland, Great
Britain and Mozambique under the auspices of the World Bank,
to promote mineral exploration in Mozambique. The large
amounts of new geological and geochronological data generated
in northern Mozambique, and the interpretation thereof,
have proven particularly useful in furthering our understanding
Gondwana processes in this part of the belt.

are the transport pathways for groundwater and groundwater

to key structural elements with the Naukluft Mountains?
What is the hydrological potential of the Naukluft Mountains
in terms of quantity and quality of water and what is the
spatial and temporal variation of these parameters within
How are human activities impacting on the hydrological potential
of the Naukluft Mountains and their capacity to provide
a source of water for future development of the coastal
region of Namibia around the Namib sand sea and the towns
of Walvis Bay and Swakopmund?
