Abstract Damage zones of different fault types are investigated in siliciclastics (Utah, USA), carbonates (Majella Mountain, Italy) and metamorphic rocks (western Norway). The study was conducted taking measurements deformation features such as fractures bands on multiple 1D scanlines along walls. resulting datasets used to plot the frequency distribution constrain geometrical width damage zone for studied faults. damage-zone a single is constrained by identifying changes slope cumulative...

Abstract A new sedimentological technique has been tested in Gelasian cross-stratified, bio-siliciclastic deposits cropping out southern Italy (Lucanian Apennine) to disentangle paleoenvironmental and model reconstructions for shallow-water mixed sediments. The proposed method suggests the use of bioclastic/siliciclastic ratio (bls), Segregation Index (S.I.) evaluate percentage dominant elastic component a deposit, order estimate degree heterolithic segregation between bioclastic...

Abstract Sandstone tidal cross‐strata are the predominant sedimentary feature of strait‐fill stratigraphic successions. However, although widely described in numerous studies, two‐dimensional and three‐dimensional have rarely been reported to occur discrete intervals which laterally adjacent or vertically stacked, meaning this architecture has not yet fully investigated. Understanding processes responsible for changes internal features modern ancient bedforms is essential order predict...

Abstract Fieldwork forms the basis of geoscience studies. However, field activities present limitations for people with mental or physical impairments. This aspect can preclude participation in trips by certain groups students limit their experience. In recent years, new types supporting material and development accessible have been a step forward towards reduction barriers to inclusion equal opportunity. work, normal practices teaching potential solutions (and limitations) foster...

Abstract Paleoceanographic information from submarine overflows in the vicinity of oceanic gateways is major importance for resolving role ocean circulation modulating Earth’s climate. Earth system models are currently favored way to study impact on global-scale processes, but studies overflow-related deposits more suitable understand detailed changes. Such deposits, however, had not yet been documented outcrop. Here, we present a unique late Miocene contourite channel Rifian Corridor...

Abstract Interbedded contourites, turbidites and pelagites are commonplace in many deep‐water slope environments. However, the distinction between these different facies remains a source of controversy. This detailed study calcareous contourites associated deep‐marine from an Eocene–Miocene sedimentary succession on Cyprus clearly documents diagnostic value microfacies this debate. In particular, variability archetypical bi‐gradational contourite sequences their internal subdivision...

An accurate and reliable description of the porosity-permeability relationship in geological materials is valuable understanding subsurface fluid movement. This important for reservoir characterisation, energy exploitation, carbon storage (GCS) groundwater contamination remediation. Whilst between pore characteristics porosity permeability are well examined, further investigation into influence grain on would be beneficial due to inherent grains pores. work aims determine whether...

Abstract Idealized facies of bottom current deposits (contourites) have been established for fine‐grained contourite drifts in modern deep‐marine sedimentary environments. Their equivalent the ancient record however are only scarcely recognized due to weathered nature most outcrop. Facies related erosional elements (i.e. channels) depositional systems not yet properly and outcrop appear non‐existent. To better understand sequences contourites, upper Miocene South Rifian Corridor (Morocco) is...

Abstract Mineral trapping (MT)is the most secure method of sequestering carbon for geologically significant periods time. The processes behind MT fundamentally occur at pore scale, therefore understanding which factors control this scale is crucial. We present a finite elements advection–diffusion–reaction numerical model uses true geometry domains generated from $$\upmu$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mi>μ</mml:mi> </mml:math> CT imaging.

Permeability variations due to sedimentological heterogeneity are important in controlling CO2 migration pathways, plume dynamics, and stratigraphic, capillary dissolution trapping of subsurface storage units complexes. Thus, knowing these parameters is crucial developing a injection strategy that maximizes efficiency. In this study we analyzed the permeability Bunter Sandstone Formation at Endurance site, offshore UK, through integrated facies analysis, minipermeameter measurements, thin...

Gateways, seaways, and straits are physical elements of sedimentary basins that hierarchically distinguished based on their dimensions temporal persistence. The term ‘gateway’ applies to any oceanographic or marine connection, regardless its size (width length), duration, depth (shallow vs. deep water). Seaways broad passages, spanning from 100s 1000s kilometres in width, active the range years 10s kyr geological time. Straits narrower passageways, connecting sub-basins within larger areas,...

Mixed siliciclastic-bioclastic sediments and systems could represent useful analogues for understanding the behaviour impact of plastic in natural environments. Integration knowledge derived from various mixed can enhance our depositional processes, bedform morphology, sedimentary particles (sensu latu) distribution. Similarities how two heterogenous composing lithoclastic-plasticlastic respond to processes suggest that it be worth investigating if knowledges coming benefit each other.

Mixed siliciclastic-carbonate deposits accumulated in the passive continental margin of Arabian plate are commonly found Mesozoic stratigraphic interval southeastern Iraq. As important hydrocarbon reservoirs area, Cretaceous strata have attracted great interests researchers to study their sedimentary features, depositional processes and petrophysical properties. However, in-depth studies considering systematic evolution a mixed succession context sequence stratigraphy its control on...

During the Pliocene, along Apennines front of Southern Italy (Acerenza area), a sector wedge-top basin hosted shallow-marine siliciclastic-carbonate (-bioclastic) sedimentation. Sediments consist mixed arenites and rudites forming an up to 30 m thick unit. Based on recognition textural features, sedimentarystructures, degree segregation between siliciclastic bioclastic particles, facies analysis revealed 10 grouped into 5 associations. They suggest occurrence either wave or current dominated...

Abstract The term base‐of‐scarp is proposed for those submarine deposits controlled by a fault and physically disconnected from their more proximal counterpart located on the footwall, although genetically linked to it. These systems differ conventional fault‐controlled deltas, such as shoal‐ Gilbert‐type, because they are entirely subaqueous lack equilibrium morphology—a steady state in which system grows size without altering its shape. We present field examples of Crati Basin Messina...

Abstract Sand ridges, a common feature of modern open shelves, reflect persistent currents and sediment availability under recent transgressive conditions. They represent the largest bedforms in oceans and, as such, can yield information on long‐term oceanographic processes. However, there is limited number tidal sand ridges documented from rock record, examples regressive are scarce studies describing straits even more rare. This study analyses Gelasian succession within structurally...

Coastal areas are among the most biologically productive, dynamic and valued ecosystems on Earth. They subject to changes that greatly vary in scale, time duration additional pressures resulting from anthropogenic activities. The aim of this work was investigate shoreline evolution main environmental coastal stretch between towns Licata Gela (in Gulf Gela, Sicily, Italy). methodology used included analysis of: (i) over long- medium-term periods (1955–2019 1989–2019, respectively), (ii) dune...

The Palaeozoic carbonate basement of the Offshore Bohai Bay Basin (OBBB) presents considerable potential for hydrocarbon exploration. However, multistage tectonism and complex superimposed palaeo-karstification in area are unclear, which leads to a lack understanding on formation mechanism distribution deep reservoirs. In this study, occurrence fracture-vug network its fillings reservoirs were investigated based borehole cores, thin sections, image logs from southwestern slope OBBB's Bozhong...
