Abstract Subduction zones serve as carbon recycling centers, where vast amassments of geologic accrete or subduct through thermogenic gas windows over millions years. We focus on New Zealand's Chatham Rise, a fossilized accretionary wedge remnant the ∼400 Myr‐active East Gondwanan margin. undertake an amplitude‐variation‐with‐offset (AVO)‐based seismic analysis abiogenic Mesozoic sedimentary sequence (MES) and overlying Sequence Y chalk interval, which span Rise's northwestern slope....
Abstract Bottom simulating reflections (BSRs) interpreted in seismic data are one of the most used indicators for presence gas hydrates. In numerous hydrate provinces, including Hikurangi margin, east New Zealand, distinct and anomalous gaps reflectivity punctuate otherwise continuous BSRs. We undertake a stratigraphic structural interpretation dense grid two‐dimensional reflection to investigate possible causes widespread BSR that occur near hinge area synclines. explain these with...
Characterising an active subduction margin's deeply-buried fluid and pressure regime is imperative when addressing seismogenic potential. Deep, compaction-related expulsion of fluids (e.g. H2O CH4) may fundamentally influence plate coupling by locally modifying the interface's frictional regime. Seismogenesis slip patterns at a interface are often directly controlled occurrence accumulated normal high pressures. As part wider study into potential southern Hikurangi Subduction Margin (HSM),...
