Detailed, high-resolution documentation of forearc basin fi ll is scarce in the literature.In this geological and geophysical study, we investigated the Pleistocene sedimentary rec ord of the tectonically active Hawke Bay forearc domain of the Hikurangi subduction margin of New Zealand. Interpretation of an extensive seismic-refl ection data set that is correlated with marine cores and onshore geological maps identifi es the detailed stratigraphic architecture of the last ~1.1 m.y. This analysis reveals the infl uences and interactions of tectonic deformation, climate, eustasy, and isostasy on forearc basin sedimentation. Eleven ~100 k.y. depositional sequences are recognized in the basin fi ll, thus highlighting the dominance of Pleistocene climate-eustasy on sequence development. The stacking pattern and isopach maps of sequences exhibit an overall retrogradational trend and an arcward migration of depocenters. These trends progressively develop a basinwide diachronous and composite erosion unconformity formed by the lateral succession and landward encroachment of the 12 sequence-bounding unconformities (S12 to S1). Among these, the S5 surface (ca. 430 ka) is an angular unconformity that separates major megasequences of the sedimentary record. The forearc domain evolved from a series of ridge-parallel basins to a succession of connected basins that have progressively developed around major, growing thrust-faulted ridges since ca. 430 ka. This change in basin confi guration and associated signifi cant increase of the preserved sediment fl uxes occurred synchronous with the reactivation of major out-of-sequence thrusts and the completion of the mid-Pleistocene transition.

“…Forearc systems develop on the subducting oceanic lithosphere ahead of the overriding orogenic wedge/magmatic arc (Dickinson, ; Dickinson & Seely, ). From sea to land, these systems are classically composed of a distal trench basin, an outer subduction wedge, including a frontal accretionary prism and a middle prism (structural high) overlapped by trench slope basins, and an inner crustal wedge corresponding to the orogenic wedge/magmatic arc overlapped by a forearc depocenter (Bailleul et al, ; Noda, ). Modern forearc systems are tectonically active and associated with faulting, vertical motions, and volcanism, and they are the site of largest and most destructive earthquakes and tsunamis (e.g., Benavente et al, ; Bilek, ; Hall et al, ; Saillard et al, ; Schurr et al, ; Villegas‐Lanza et al, ).…”

Deciphering the Late Cretaceous‐Cenozoic Structural Evolution of the North Peruvian Forearc System

et al. 2018

The link between plate tectonics and the evolution of active margins is still an ongoing task to challenge since the acceptance of plate tectonic paradigm. This paper aims at deciphering the structural architecture and uplift history of the North Peruvian forearc system to better understand the evolution and the mechanics that govern the Late Cretaceous‐Cenozoic building of this active margin. In this study, we report surface structural geology data, interpretation of seismic reflection profiles, apatite fission track data, and the construction of two offshore‐onshore crustal‐scale balanced cross sections. The structure of the North Peruvian forearc system is dominated by an accretionary style with northwestward propagation of thrust‐related structural highs involving continental/oceanic basement rocks and off‐scrapped sediments. The thrust systems bound thick thrust‐top forearc depocenters mainly deformed by crustal normal to strike‐slip faults and thin‐skinned gravitational instabilities. The sequential restoration of the margin calibrated with apatite fission track data suggests a correlation between uplift, shortening, and plate convergence velocity during Late Cretaceous and Miocene. Pliocene‐Quaternary shortening and uplift of the coastal zone is rather related to the subduction of asperities during convergence rate decrease. The development of crustal normal to strike‐slip faulting and subsidence zones might be the consequence of slab flexure, local basal erosion along subduction fault, and/or oblique subduction associated with sediment loading control. We conclude that the evolution of the North Peruvian forearc system was controlled by subduction dynamics, strong sediment accumulation, and recent ridge subduction, and it recorded the orogenic loading evolution of the Andes over the Cenozoic.

“…Stratigraphy of the Neogene section is spatially and temporally variable, however, and is closely linked to Cenozoic structural development. Out‐of‐sequence thrusting during compression created margin‐parallel, elongate sub‐basins with distinct sediment‐filling histories (Chanier & Ferrière, ; Barnes et al ., ; Field et al ., ; Bailleul et al ., , ; Burgreen & Graham, ). Although sedimentation was dominated by mudstone deposition, sand‐rich turbidites were deposited within bathymetric lows and limestones are locally observed on structural palaeo‐highs (Bailleul et al ., ).…”

“…The basin experienced three phases of Neogene deformation including: (1) a compressional phase from 25 Ma through ca . 15 Ma resulting in extensive reverse faulting and uplift (Chanier, ; Rait, ; Bailleul et al ., ), (2) a mixed compressional and extensional phase, where extension occurred primarily in the Hawke's Bay region from ca . 15 Ma through 5–6 Ma resulting in normal faulting and subsidence, while compression continued in other regions of the basin (Chanier, ; Barnes et al ., ) and (3) a renewed compressional phase from 5–6 Ma through present‐day resulting in reverse faulting and uplift (Chanier, ; Nicol et al ., , ; Nicol & Beavan, ).…”

Basin and petroleum system modelling of the East Coast Basin, New Zealand: a test of overpressure scenarios in a convergent margin

2015

In the East Coast Basin (ECB), an active convergent margin of the North Island, New Zealand, the smectite-rich Eocene Wanstead Formation forms an effective regional seal, creating high overpressure in the underlying Cretaceous through Palaeocene units due to disequilibrium compaction. This study examines the evolution of pore pressure and porosity in Hawke Bay of the ECB based on stepwise structural reconstruction of a stratigraphic and structural framework derived from interpretation of a regional two-dimensional seismic line. This framework is incorporated into a basin and petroleum system model to predict the generation, distribution, and dissipation of overpressure, and examine the influence of faults, erosion, structural thickening, and seal effectiveness of the Wanstead Formation on pore pressure evolution. We find that natural hydraulic fracturing is likely occurring in sub-Wanstead source rocks, which makes it a favourable setting for potential shale gas plays. We use poroelastic modelling to investigate the impact of horizontal bulk shortening due to tectonic compression on pore pressure and the relative order of principal stresses. We find that shortening modestly increases pore pressure. When 5% or greater shortening occurs, the horizontal stress may approach and exceed vertical stress in the last 4 Myr of the basin's history. Shortening impacts both the magnitude and relative order of principal stresses through geological time. Due to the overpressured nature of the basin, we suggest that subtle changes in stress regime are responsible for the significant changes in structural deformational styles observed, enabling compressional, extensional, and strike-slip fault regimes to all occur during the tectonic history and, at times, simultaneously.
