DEEP FAULT DRILLING PROJECT (DFDP) - ALPINE FAULT, NEW ZEALAND

ICDP Workshop on Active Deformation Processes in the Seismogenic Zone of a Major Transpressional Plate Boundary Fault

Franz Josef Glacier, New Zealand, 22-28 March 2009

The Alpine Fault, New Zealand, is a dextral-reverse fault that fails in large earthquakes (c. Mw 7.9) every 200-400 years and last ruptured in 1717 AD.  Rock uplift has exhumed a young (<1 Ma), well-preserved sample of the structures currently active in the middle and upper crust.  The remarkable along-strike homogeneity of rock type, rapid rate of slip, and fault geometry and kinematics enable us to examine the progressive evolution of fault zone materials by targeting a single rock mass at two points on its exhumation trajectory: one at the surface, and one in a borehole several kilometres deep.  The transition from brittle to ductile behaviour is inferred to be relatively shallow (4-10 km), providing a unique opportunity to sample mid-crustal materials and study active processes. 

An ICDP-funded workshop will be held at Franz Josef Glacier (West Coast, South Island) on 22-28 March 2009.  Participants will discuss the scientific goals and the technical and logistical challenges of a multi-year deep-drilling experiment.  The principal workshop outcome will be a draft science plan addressing further site characterisation, drilling, and monitoring.  Fieldtrips to the Alpine fault will be held during the workshop. 

We invite applications from members of the international scientific and engineering communities to attend this workshop.  Applications should include full contact details, a summary of your research interests and expertise, and a brief description of your intended contribution.  We particularly seek expertise in the fields of structural geology, tectonics, petrology, hydrological modelling, geochemistry and geochronology, geophysics, earthquake physics, and scientific drilling. 

Participants will be selected by the workshop advisory committee and notified by 30 November 2008.  Accommodation and registration costs will be met by ICDP and limited travel assistance for overseas participants may also be available.  Preference will be given to scientists of ICDP member countries.
