摘要
The Hikurangi Subduction Zone (HSZ), New Zealand, accommodates westward subduction of the Pacific Plate. Where imaged seismically, the shallow HSZ decollement (<10-15 km depth) occurs within or along the upper contact of Late Cretaceous-Paleogene (70-32 million-year-old) sediments. The frictional properties of Paleogene sediments recovered from Ocean Drilling Program Leg 181, Site 1124 were measured at 60 MPa effective normal stress and varying sliding velocities (V = 0.3-30 mu m/s) and temperatures (T = 25-225 degrees C). Velocity-stepping experiments were conducted at temperatures of 25 degrees C, 75 degrees C, 150 degrees C, and 225 degrees C to determine the friction rate parameter (a-b). Paleocene and Oligocene clay-bearing nannofossil chalks (mu = 0.45-0.61) and a middle Eocene clayey nannofossil chalk (mu = 0.35-0.51) are frictionally stronger than smectite-bearing Eocene clays (mu = 0.16-0.31). With increasing temperature, chalks show rate-strengthening to rate-weakening frictional stability trends; clays show rate-weakening and rate-neutral to rate-strengthening frictional stability trends. The results obtained from Site 1124 sediments indicate that: (1) fault-zone weakness may not require pore-fluid overpressures; (2) clays and chalks can host frictional instabilities; and (3) heterogeneous frictional properties can promote variable slip behaviour.
