“…Many studies have related the genesis of relict cave levels and their subsequent abandonment to base‐level dynamics, driven by river incision in fluvial valleys or sea‐level oscillations in coastal areas (Plan et al ., 2009; Piccini and Landelli, 2011; Audra and Palmer, 2013; Calvet et al ., 2015; Columbu et al ., 2015; Nehme et al ., 2016; Pennos et al ., 2016; Harmand et al ., 2017; Bella et al ., 2019). The rate of river incision is influenced by several variables.…”

“…In high‐latitude areas where periglacial/glacial processes are the dominant influence on Quaternary valley incision, climatically forced incision and aggradation (Aranburu et al ., 2014) influences the development of cave levels. Each phase of fluvial incision and base‐level fall increased the hydraulic gradient in the chalk aquifer, causing a reorganization of the conduit system (Harmand et al ., 2017). These respond to base‐level fall by the development of new phreatic conduits graded to the lower base level, and/or by vadose incision of the existing passage.…”

Quantifying rates of river incision and continental uplift over Quaternary timescales offer the potential for modelling landscape change due to tectonic and climatic forcing. In many areas, river terraces form datable archives that help constrain the timing and rate of valley incision. However, old river terraces, with high‐level deposits, are prone to weathering and often lack datable material. Where valleys are incised through karst areas, caves and sediments can be used to reconstruct the landscape evolution because they can record the elevation of palaeo‐water tables and contain preserved datable material. In Normandy (N. France), the Seine River is entrenched into an extensive karstic chalk plateau. Previous estimates of valley incision were hampered by the lack of preserved datable fluvial terraces. A stack of abandoned phreatic cave passages preserved in the sides of the Seine valley can be used to reconstruct the landscape evolution of the region. Combining geomorphological observations, palaeomagnetic and U/Th dating of speleothem and sediments in eight caves along the Lower Seine valley, we have constructed a new age model for cave development and valley incision. Six identified cave levels up to ∼100 m a.s.l. were formed during the last ~1 Ma, coeval with the incision of the Seine River. Passage morphologies indicate that the caves formed in a shallow phreatic/epiphreatic setting, modified by sediment influxes. The valley's maximum age is constrained by the occurrence of late Pliocene marine sand. Palaeomagnetic dating of cave infills indicates that the highest‐level caves were being infilled prior to 1.1 Ma. The evidence from the studied caves, complemented by fluvial terrace sequences, indicates that rapid river incision occurred during marine isotope stage (MIS) 28 to 20 (0.8–1 Ma), with maximal rates of ~0.30 m ka−1, dropping to ~0.08 m ka−1 between MIS 20–11 (0.8–0.4 Ma) and 0.05 m ka−1 from MIS 5 to the present time. © 2020 John Wiley & Sons, Ltd.

“…In our study, few evidences for tectonic control of fluvial sedimentation can be found (Allen, Fielding, Rygel, & Gibling, 2013;Harmand et al, 2017). In contrast, climatic variations have undoubtedly been significant in influencing on stratigraphic architectural in many continental settings (Gibling, Fielding, & Sinha, 2011;Maccarrick & Loeys, 2005;Maddy, 2002;Weissmann, Mount, & Fogg, 2002), especially in the evolution of sedimentation in the Junggar Basin in varying degrees (Khadkikar et al, 1999;Mader & Redfern, 2011;Vandenberghe, 2003).…”

This paper presents the current body of knowledge regarding the evolution of a braided–meandering system in the southern Junggar Basin, north‐west China, based on the preserved architecture evidences. The response to climate change was also discussed. Herein, 10 types of lithofacies are summarized, including information of their primary sedimentary structures, characteristic lithology, and geometry. This study focuses on recognizing the architectural elements within the channels (migrating channel: CHm, switching channel: CHs, transiting channel: CHt, and filling channel: CHf), the bar units (downstream accretion: DA, lateral accretion: LA, unit bar: UB, and compound bar: CB), and fine‐grained clastic deposits (floodplain fines: FF and overbank fines: OF). Three representative sections of outcrops were selected, and detailed observation and analysis of these sections revealed 3 stages can be divided: the braided stage, in which the deposits show an evidence of CHm, DA elements which are the mainly architectural elements, multichannel with aggradational filling; The transformation between braided–meandering stage, during which the fluvial system consists of CHt and CHm elements with lateral accretion; and meandering stage which is characterized by dominance of CHm, LA elements, and the channels become isolated and meandering. Finally, this paper concludes with an interpretation of climate events as manifested by the fluvial archives of the colours of sedimentary rocks, special mineral, palaeontology, geochemistry spanning the Middle–Upper Jurassic (between 166.1 and 152.1 Ma).

“…In general, the telogenetic karst environment could vertically be subdivided into an epikarstic, vadose, and phreatic zone (Harmand et al, ). This is also the case for the Majiagou Formation in the Jingxi area, which is evidenced by petrographic analyses.…”

Seepage reflux dolomitization and telogenetic karstification in Majiagou Formation in the Ordos Basin, China

This study investigates the characteristics of the heterogeneous carbonate reservoir of Majiagou Formation in Jingxi area, Ordos Basin, China, to explain the diagenetic control and distribution of high‐quality reservoir intervals. The carbonates of the study area mainly consist of silt‐sized crystalline dolomite, microcrystalline dolomite, and microcrystalline limey dolomite. Both dolomite content and dolomite size gradually decrease both from top to bottom and from slope to basin. Intercrystalline pores exist in the silt‐sized crystalline dolomite, and vuggy pores and fractures mainly developed in microcrystalline (limey) dolomite. Furthermore, typical geopetal infills and three stages of calcite cements could be differentiated. Based on petrographical and geochemical analysis, the reservoir is dominantly controlled by seepage reflux dolomitization and telogenetic karstification. Four reservoir evolutions could be differentiated. The reservoir in the first model is dominated by intercrystal porosity occurring in silt‐sized crystalline dolostone. It experienced strong dolomitization, telogenetic karstification, and shallow as well as deep burial cementation. The reservoir in the second model consists of only a small amount of high‐angle dissolution fissures and vertical dissolution cavities in microcrystalline (limey) dolostone. It experienced relatively weak dolomitization, strong telogenetic karstification, and two important calcite cementation events. The reservoir in the third model is marked by many vuggy pores and dissolution fractures, occurring in microcrystalline (limey) dolostone. The strata experienced relatively weak dolomitization, strong telogenetic karstification, and two weak calcite cementation episodes. The reservoir in the fourth model is dominated by fractures and their related dissolution pores, which developed in microcrystalline (limey) dolostone. These dolostones experienced relatively weak dolomitization, telogenetic karstification, and calcite cementation. From a reservoir point of view, the reservoirs represented by the first and third models, which respectively are composed of silt‐sized crystalline dolomite occurring in the top of the whole dolostone succession and the dolomite affected by telogenetic karstification, are the most vital exploration targets.
