Timothy John Sherry BS 2011 (with Honors) (co-supervised by Jamie Kirkpatrick)
Syn-flow lamination and meso-scale banding in the Yellow Bank Beach Injection
The Yellow Bank Beach clastic injection is a km-scale body of coarse sand which flowed upward into the overlying Monterey Formation diatomites. The sand body has complicated micro-to outcrop textures which include millimeter-scale distorted lamination, meso-scale (10-centimeter) 'kink bands' offsetting the lamination. Regions of hematite cement and regions of black tar-stained dolomite cement both follow and/or crosscut the granular structure. Tim's thesis work involved determining the direct microstructure of the laminations to differentiate between the roles of grain packing, grain composition, aspect ratio, and alignment in creating the observed micro- and meso-fabrics. Tim's work was published in G3 in 2012. He is currently a Ph.D. student at McGill University.

Carly Faber BSc Hons 2009 (First Class)
Silica gel as a possible indicator of paleoseismic slip: A natural example
An apparent paradox arises from the study of earthquake- generating faults which sometimes appear to be strong and sometimes weak, particularly during earthquakes. Several mechanisms for co-seismic weakening have been suggested by laboratory and numerical studies, but natural examples are rare. Carly Faber has examined a possible example of a preserved layer of co-seismically produced silica gel in the Olive Fault, Namibia. Her study represents the best-characterized natural example to date. Carly got a first- class mark for her BSc Hons thesis describing this work in 2009 and presented her results at the American Geophysical Union Fall Meeting. Click here to download her poster. She submitted these results for publication in June, 2010. Carly received her MSc with distinction at UCT in 2012 and is currently a PhD student at the University of Tromso, Norway.

Fernando Yorich Gurschzon Sylvester BSc Hons 2009
Changes in fault rock style with fault surface orientation in a continental decollement
Fernando Y. G. Sylvester mapped the detailed geometry of the Naukluft Thrust, basal decollement to the Naukluft Nappe Complex in central Namibia. Fernando's work showed that contrary to previous studies, the thrust surface is not planar but corregated and locally ramping upward in the transport direction. Additionally, Fernando's work showed that the evolution of characteristic "gritty dolomite" fault rock is more spatially heterogeneous and complex in its development than previously reported. Fernando is an exploration geophysicist at Tullo Oil in Cape Town, and completing his MBA.

Simon Baer BSc Hons 2009 (co-supervised by Chris Harris)
Fluid-rock interaction during shear and exhumation of the Colenso Fault, Saldania Belt
Simon Baer studied the evolution of the Colenso Fault in the Saldania Belt of the Western Cape, South Africa, exposed where it deformed the Cape Granite Suite in progressively ductile to brittle fabric during regional uplift. Simon compared the deformation fabrics to the oxygen isotope patterns in and around the fault zone and concluded that significant water-rock interaction could be correlated with fault exhumation, and that temperatures suggested by deformation of different minerals are consistent with those suggested by the oxygen isotopes. Simon is continuing his studies in Germany.

Taufeeq Dhansay BSc Hons 2008 (co-supervised by Johann Diener and Jodie Miller)
Dehydration along fluid pathways during lower-crustal strain in the Mozambique Belt
Taufeeq Dhansay investigated a melt transport network in a mid-crustal deformation zone in the Mozambique Belt. Taufeeq's work showed that distributed pathway development allowed the injection of melt along a network of simultaneously open fractures. The melt, or associated fluids, had extremely low aH2O during migration and altered the host rock to charnockite. Taufeeq received his MSc with Distinction from Nelson Mandela Metropolitan University in 2013 and is continuing his career with the mapping unit of the Council for Geoscience (South African Geological Survey).

Nils Rainer Backeberg BSc Hons 2008
Ordovician Mega-scale soft sediment deformation at De Balie, Cederberg Mts, SA
Nils Backeberg investigated the 50m-scale "Fold Zone" in the upper Peninsula Formation and lower Pakhuis Formation of South Africa's Table Mountain Group. He concluded that the Fold Zone formed not due to subglacial shear, as previously reported, but by fluid escape on a catastrophic scale from unconsolidated sediments. Thermal destablization of ice or clathrates may explain the proximal cause of this event. Nils received his BSc Honours degree for this work in 2008 and published in 2009 in South African Journal of Geology. Click here to download the manuscript. Nils received his MSc from UCT in 2011, and is currently a Ph.D. student at McGill University.

Scott Angus Maclennan BSc Hons 2008 (cosupervised by Maarten de Wit)
Structural differentiation between Saldanian and Cape Deformation, Kaaimansgat, SA
Scott Maclennan mapped the large doubly-plunging anticline in Kaaimansgat, in the heart of the Cape Fold Belt Syntaxis, where the previously deformed Neoproterozoic Malmesbury Group is overlain by the Cape Supergroup. The area was later subject to complex interference folding and rotations during the Permo-Triassic Cape Orogeny. Scott used multiple datasets to attempt to untangle the structural history and effect of Cape-age overprinting on the observed geometries. This work earned Scotty a BSc Honours degree in 2008 and he presented a field trip to the Western Cape Branch of the GSSA - download field trip guide here. Scott received his MSc from UCT in 2012 and is now a PhD student at Princeton University.
