Abstract Pangea results from the progressive amalgamation of continental blocks achieved at 320 Ma. Assuming that ancient concept “active” versus “passive” rifting remains pertinent as end‐members more complex processes, we show breakup occurred through a succession episodes characterized by different tectonic evolutions. A first episode passive during Upper Carboniferous and Permian led to formation Neo‐Tethys Ocean. Then beginning Triassic times, two short active associated Siberian...

Abstract: The Late Triassic synrift succession of the Minas sub-basin (Bay Fundy, Nova Scotia) includes a fluvio-alluvial fan-dominated unit (lower and middle Wolfville Formation), transitional fluvio-playa (upper Formation) an upper playa-dominated package (Blomidon Formation). We describe facies development in 240 m thick Formation, examine vertical stacking patterns develop depositional model for this succession. comprises channelized unconfined fluvial deposits interbedded with aeolian...

Abstract The Early Cretaceous hyperextended Mauléon rift is localized in the north‐western Pyrenean orogen. We infer Tertiary evolution of basin through restoration a 153‐km‐long crustal‐scale balanced cross‐section belt, which documents at least 67 km (31%) orogenic shortening Western Pyrenees. Initial shortening, accommodated inversion inherited crustal structures, led to formation pop‐up structure, opposite edges underwent similar with different tectonic reactivation styles, versus....

Abstract Sandstone provenance studies can help constrain palaeogeographic reconstructions and ancient drainage system scales pathways. However, these insights be obscured by difficulties in geochemically distinguishing or adequately characterizing potential sourcelands, failure to identify sedimentary recycling. Triassic basins west of Shetland accumulated ∼2.5 km sand‐rich sediment. The Middle‐Upper Foula Formation represents fluvial, aeolian sabkha facies deposited the northern interior...

Abstract Determining what the controls are on large-scale (> 10 km) horizontal architecture of coarse-grained fluvial deposits is important for understanding subsurface fluid distribution and extraction from these aquifers hydrocarbon reservoirs. This contribution describes sediments an almost continuous lateral profile 27 km long by 115 m high in Upper Triassic Wolfville Formation, (Fundy Basin, Nova Scotia). The extent quality exposure allows development a high-resolution correlation...

The early Devonian, Old Red Sandstone succession at St. Cyrus, NE Scotland, includes the exceptional preservation of a lava field and its associated fluvial drainage system. developed through punctuated eruptions low-volume pāhoehoe lava, fed by tubes. During periods rapid effusion, groundwater systems were able to transmit most recharge in subsurface, probably springs, where there areas localized low permeability, ephemeral lakes developed. Subsequent flows underwent significant interaction...

ABSTRACT Along‐strike variability within a Late Cretaceous to early Palaeocene contractional growth structure and associated alluvial fan deposits is documented at the northern margin of Arc Basin (Provence, SE France). This contribution shows that fans can be used as high‐resolution proxies reconstruct structural segmentation palaeo‐geomorphological evolution source/basin system. Facies‐based reconstruction allows spatial temporal distribution bodies mapped. Relationships between area...

Abstract Permo-Triassic rift basins offer important hydrocarbon targets along the Atlantic margins. Their fill is dominated by continental red beds, comprising braided fluvial, alluvial fan, aeolian, floodplain and lacustrine facies. These relatively lightly explored span both Tethyan domains developed above a complex basement with inherited structural fabrics. Sparse data in offshore regions constrain understanding of depositional geometries sedimentary architecture, further impeded their...

Abstract Architectural-element analysis was developed to describe and reconstruct fluvial system stacking patterns understand the controls on architecture. The architecture of braided systems at scale channel belts is still poorly understood, upscaling from outcrop observations basin-scale remains partly speculative. Nonetheless, predictive sedimentary models are necessary connectivity sand bodies small (outcrop) basin scale. This contribution presents a dataset Late Triassic sandy Fundy...

Abstract Upper Cretaceous-Palaeocene alluvial-fan conglomerates exposed along the northern margin of Arc Basin (Provence, SE France) preserve a continuum between undeformed basinal deposits and syntectonic deposits. Based on distribution facies associations growth structures in deposits, using marker levels erosional surfaces, tectono-sedimentary evolution basin is discussed. On long timescale, stratigraphic pattern mainly records tectonic activity catchment, subordinate out-of-syncline...

The relationship between movement on the Highland Boundary Fault and deposition of Lower Old Red Sandstone in Midland Valley Basin Scotland is controversial. Most models favour mid-Silurian to early Devonian sinistral development a transtensional Basin. To constrain during late Silurian, we examine basal alluvial succession exposed adjacent Fault. A lack synsedimentary fault indicators, coupled with an increase stratal thickness across fault, indicates that was not active sedimentation....

Abstract The Triassic Fundy rift basin in Nova Scotia is a large (>70 km wide) half-graben filled with alluvial, lacustrine and aeolian deposits. A major lithospheric lineament, the Cobequid–Chedabucto Fault Zone (CCFZ), which forms tip of Newfoundland–Gibraltar Zone, occurs within Basin. timing early movement on this important fault zone poorly constrained. We present data from alluvial units that crop out adjacent to CCFZ Minas sub-basin determine initiation movement. use onset fan...

Continental-dominated successions are often poorly constrained stratigraphically due to a lack of robust biostratigraphic markers.
