“…It is noteworthy that many processes that promote the development of deformations and shifts in topography, engendering changes in accommodation rates that are not directly related to geotectonics, such as halokinesis (e.g., Rojo et al 2020), sedimentary compaction (e.g., Khani and Back 2015), and glacio-isostatic adjustment (e.g., Dietrich et al 2018).…”

Cyclicity and hierarchy in sequence stratigraphy: an integrated approach

With standardized methodology and nomenclature, the sequence stratigraphy aims to characterize multi-scale cyclical units of genetically related rocks into a hierarchical chronostratigraphic framework. From facies to basin scale, the stacking patterns and stratigraphic surfaces are recognized as sequence elements. In parallel, Earth sciences have developed a sophisticated understanding of geological processes (tectonic, climatic, and eustatic) that produce the main cyclicity observed in the sedimentary rock record. This review paper discusses how the elaboration of hierarchical stratigraphic frameworks that incorporate the knowledge of these periodic geological processes -from high-to low-frequencies -as the control of generation and preservation of sequences -from high-to low-resolutions -guarantees objective results in predicting vertical recurrence and the lateral correlation of genetic stratigraphic units. This interpretive approach of cyclic stratigraphic analysis supports the development of effective observable criteria to identify and rank sequences in multiple scales, based on cycle anatomy, recurrence, vertical trends, and mappability. This methodological improvement reduces the inaccuracies and contradictions of traditional conceptual models based on fully preserved three-dimensional depositional systems.

“…The fact that the thickest part of Hardangerfjord delta is located in the hanging wall of F3 ( Fig. 8) and that F3, in addition to a relatively small portion of ØFS5, are the only faults reactivated after the ~70 myr period of inactivity between Late syn-RP1 (?Early Triassic) and syn-RP2 (Middle Jurassic), together suggest that the reactivation of F3 might be triggered by differential sedimentary loading (Fazlikhani & Back, 2015) associated with westward progradation of the Hardangerfjord delta. However, a combination of sedimentary loading and crustal extension during syn-RP2 might also explain the reactivation of F3.…”

Strain migration during multiphase extension, Stord Basin, northern North Sea rift

et al. 2020

In multirifted regions, rift-related strain varies along and across the basin during and between each extensional event, and the location of maximum extension often differs between rift phases. Despite having a general understanding of multiphase rift kinematics, it remains unclear why some parts of the rift are abandoned, with strain accumulating in previously less deformed areas, and how seismic and sub-seismic scale pre-existing structures influence fault and basin geometries. We study the Stord Basin, northern North Sea, a location characterized by strain migration between two rift episodes. To reveal and quantify the kinematics, we interpreted a dense grid of 2D seismic reflection profiles, produced time-structure and isochore maps, collected quantitative fault kinematic data and calculated the amount of extension (β-factor). Our results show that the locations of basin-bounding fault systems were controlled by pre-existing crustal-scale shear zones. Within the basin, rift faults mainly developed at high angles to the Permo-Triassic Rift Phase 1 (RP1) E-W extension. Rift faults control the locus of syn-RP1 deposition, whilst during the inter-rift stage, sedimentary processes (e.g. areas of clastic wedge progradation) are more important in controlling sediment thickness trends. The calculated amount of RP1 extension (β-factor) for the Stord Basin is up to β=1.55 (±10%, 55% extension). During Middle Jurassic-Early Cretaceous (Rift Phase 2, RP2) however, strain localises to the west along the present axis of the South Viking Graben, with the Stord Basin being almost completely abandoned. Migration of rift axis during RP2 is interpreted to be related to the changes in lithospheric strength profile and possible underplating due to the ultraslow extension (<2mm/yr during RP1) and the long period of tectonic quiescence (ca. 70 myr) between RP1 and RP2. Our results highlight the very heterogeneous nature of temporal and lateral strain migration during and between extension phases within a single rift basin.

M., Kováè, M., Hók, J., Šujan, M., Braucher, R., Rybár, S., de Leeuw, A., 2017. Late Mio cene flu vial distributary system in the north ern Dan ube Ba sin (Pannonian Ba sin Sys tem): depositional pro cesses, strati graphic ar chi tec ture and con trolling fac tors of the Piešïany Mem ber (Volkovce For ma tion). Geo log i cal Quar terly, 61 (3): 521-548, doi: 10.7306/gq.1360Aim of the study was to in ves ti gate the de tailed strati graphic ar chi tec ture of the al lu vial Volkovce For ma tion, which was de pos ited in the north ern Dan ube Ba sin dur ing the in ter val be tween 10 and 6 Ma. Two type lo cal ity ex po sures were sub ject to fa cies anal y sis and in ter pre ta tion of depositional pro cesses and >500 bore holes served for cor re la tion of spa tial vari abil ity in the char ac ter of the for ma tion. The study was fo cused on the north ern Blatné and west ern Rišòovce de pres sions, which are partly sep a rated by the Považský Inovec Moun tains horst. It was re vealed, that a mostly grav elly flu vial distributary system of the Piešïany Mem ber was de pos ited in the north ern Blatné de pres sion, partly con fined by the ex posed horst and by in cised palaeotopography. The se quence is com posed of amal gam ated braided river chan nel bod ies with no overbank strata, in re sponse to high sed i ment sup ply and low ac com mo da tion. The palaeo-stream then crossed the horst in its southern part to wards the Rišòovce de pres sion, where there was four times more ac com mo da tion. The sub merged horst acted as a bound ary, where the depositional pro cesses changed to a me an der ing river and sig nif i cant overbank de pos its started to be pre served. Only small streams were pres ent in the north ern Rišòovce de pres sion, which led to very low sed i ment sup ply com pared to the high ac com mo da tion there. The depositional sys tem was af fected mainly by the in cised palaeotopography, by the lo ca tion of sed i ment in put to gether with spa tial dif fer ences in ac com mo da tion rate caused by the ac tiv ity of the Ripòany Fault on the south east ern side of the Považský Inovec Mts.
