Whole rock geochemical data from the Alpine Fault Zone. These data have been generated from systematic sampling through the Deep Fault Drilling Project - Phase 1 rock cores and from analyses of cuttings retrieved during the Deep Fault Drilling Project - Phase 2. Geochemical analyses on the fault rocks to understand the conditions at which they were deformed. The dataset is associated with the UK component of a major international campaign, the Deep Fault Drilling Project (DFDP). to drill a series of holes into the Alpine Fault, New Zealand. The overarching aim of the DFDP to understand better the processes that lead to major earthquakes by taking cores and observing a major continental fault during its build up to a large seismic event.

The dataset consists of a spreadsheet containing whole rock geochemistry (Major and trace elements, Hf isotopes) from 7 samples and zircon U-Pb, O, Hf isotope and trace elements compositions (>200 spots on zircons from 7 samples) analysed by Ion Microprobe (NERC EIMF) and MC-LA-ICP-MS (NIGL). The samples are Eoarchaean amphibolite-facies mafic gneisses and a pegmatite as well as granulite-facies mafic gneiss and migmatite (melano- and leucosome) from the Kapuskasing uplift in Ontario, Canada.
