The lagoonal and shallow marine sediments of the Penarth Group in UK span Triassic–Jurassic boundary. These contain several disturbed levels with soft sediment deformations (SSDs), such as synsedimentary faults, injective domes, recumbent folds slumps that are recognised most basins from SW England South Wales to NW Northern Ireland. Field observations, notably close link SSDs active attest an ...

Abstract A 200 m thick drill core penetrating the Givetian Hahnstätten Reef in southwestern Lahn Syncline (Rhenish Massif) was investigated. range of different depositional environments is described based on lithofacies and microfacies analysis. All all, nine types (FTs) are distinguished, which can include subfacies types. The majority these ultrapure carbonates represented by lime mudstone fe...

a r t i c l e i n f o a b s t r a c t Keywords: dolomite authigenic carbonate magnesium isotopes calcium isotopes Monterey formation Authigenic carbonates in marine sediments frequently have carbon isotope ratios that reflect local organic carbon processing rather than the δ 13 C of the global DIC (dissolved inorganic carbon) reservoir, but their contributions to ancient sedimentary sections ar...

Architecture of slopeand basin-floor-fan systems in growth-faulted subbasins along the south Texas Gulf Coast developed as a result of interplay between synsedimentary tectonics and sedimentation during third-order sea-level lowstands. These subbasins, or intraslope basins, have not been adequately explored for their slope and basin-floor-fan potential, as have the intraslope basins in salt-dom...

The Dalradian Supergroup of largely clastic metasediments in Scotland and Ireland is a well-known record Neoproterozoic to Cambrian sedimentation on the Laurentian margin. Its apparent long duration, from ∼ 800 500 Ma, has encouraged search for tectonic breaks unconformities within sequence. One suggestion that break occurred upper part Argyll Group, specifically Easdale Subgroup. Here we repor...
