This study examines soils in the highly industrialized Dunkerque agglomeration in France. Our work reveals the contamination of urban soils by metals from industrial dust, including Cr, Ni, Mo, Mn, Cd and Zn. While Cr, Ni and Mo are relatively stable in soils, Mn, Cd and Zn are more mobile and may pose environmental and health problems. Our findings highlight the need of careful consideration of future land use near industrial emitters, such as allotment gardens, due to these potential hazards.

This study explores the impact of environmental conditions on the chemistry of coccoliths, calcite minerals produced by marine algae, to better understand past climate changes. By cultivating different species of coccolithophores under various CO2 and pH levels, we have shown that the isotopic composition of certain species varies with CO2 concentration and quantified these variations.

We test a new method to reconstruct past atmospheric CO2 levels based on the geochemistry of pelagic algal biominerals (coccoliths), which recent culture and numerical experiments have related to ambient CO2 concentrations. By comparing the isotopic composition of fossil coccoliths to the inferred surface ocean CO2 level at the time they calcified, we outline a transfer function and argue that coccolith vital effects can be used to reconstruct geological pCO2 beyond the ice core record.

This work examines the effect of salinity changes on the biogeochemistry of the coccolithophores with a palaeoproxy perspective. Although substantial changes in growth rate are observed between cells grown under various salinities, these physiological changes have no significant impact on the oxygen isotope composition of their biominerals. Thus, established coccolith δ18O / temperature calibrations are not complicated by salinity. By contrast, it does influence coccolith δ13C values.

Several agroecological management options foster soil organic C stock accrual. What is behind the persistence of this "additional" C? We used three different methodological approaches and >20 years of field experiments under temperate conditions to find out. We found that the additional C is less stable at the pluri-decadal scale than the baseline C. This highlights the need to maintain agroecological practices to keep these carbon stocks at a high level over time.

This paper presents the application of a numerical method for restoring models of the subsurface to a previous state in their deformation history, acting as a numerical time machine for geological structures. The method is applied to a model based on a laboratory experiment. The results show that using force conditions in the computation of the deformation allows us to assess the value of some previously unknown physical parameters of the different materials inside the model.

We present a workflow that models the impact of stress regime change on the permeability of fractured Latemar carbonate buildup using a displacement-based linear elastic finite-element method (FEM) and outcrop data. Stress-dependent heterogeneous apertures and effective permeability were calculated and constrained by the study area's stress directions. Simulated far-field stresses at NW–SE subsidence deformation and N–S Alpine deformation increased the overall fracture aperture and permeability.

Extensional deformation creates structures that may be reactivated during subsequent shortening. The Achental structure within the Northern Calcareous Alps fold-and-thrust belt is a natural example of a basin margin that was inverted during Alpine orogeny. We have studied the influence of such inherited inhomogeneities in the field and as an analogue model. We find that oblique shortening can create structures outlining pre-existing faults within a single deformation event.

Fourier transform infrared (FTIR) was performed on shale before and after solvent extraction. The extraction yield from shale with THF is higher than other solvents. The organic-C-normalized yield of a mature sample is higher than other samples. The aromaticity of organic matter increases, and the length of organic matter aliphatic chains does not vary monotonically with increasing maturity. The results will help in the selection of organic solvents for oil-washing experiments of shale.

Traditionally, the axial part of the Polish Basin, i.e. the Mid-Polish Trough, was interpreted as the deepest and most subsiding part of the basin during the Cretaceous times. We interpret this area conversely, as representing a landmass – the Łysogóry–Dobrogea Land. Inversion-related tectonics, uplift on the one hand and enhanced subsidence on the other, drove the development of the Szozdy Delta within the axial part of the basin. New heavy mineral data suggest different burial histories.

Here we present new surface elevation constraints for the middle Miocene Central Alps based on stable and clumped isotope geochemical analyses. Our reconstructed paleoelevation estimate is supported by isotope-enabled paleoclimate simulations and indicates that the Miocene Central Alps were characterized by a heterogeneous and spatially transient topography with high elevations locally exceeding 4000 m.

Short summary
Biochemical reactions related to hydrocarbon seepage are known to induce carbonates in marine sediments. Seep carbonates may act as seals and force lateral deviations of rising hydrocarbons. However, crustacean burrows may act as efficient vertical fluid channels allowing hydrocarbons to pass through upward, thereby allowing the vertical growth of carbonate stacks over time. This mechanism may explain the origin of carbonate columns in marine sediments throughout hydrocarbon provinces worldwide.

Basin inversion in central Europe is believed to have started during Late Cretaceous (middle Turonian) and probably proceeded until the Paleogene. Data from different marginal troughs in central Europe point to an earlier start of basin inversion (in the Cenomanian). The end of inversion is overprinted by general uplift but had probably already occurred in the late Campanian to Maastrichtian. Both the start and end of inversion occurred with low rates of uplift and subsidence.

In this work, we combined different imaging and experimental measuring methods for analysis of cross-scale effects which reduce permeability of tight reservoir rocks. Simulated permeability of digital images of rocks is often overestimated, which is caused by non-resolvable clay content within the pores of a rock. By combining FIB-SEM with micro-XCT imaging, we were able to simulate the true clay mineral abundance to match experimentally measured permeability with simulated permeability.

The Kallipetra Basin, formed in the Late Cretaceous on the reworked Pelagonian–Axios–Vardar contact in the Hellenides, is described for the first time. We document how and when the basin evolved in response to tectonic forcings and basin inversion. Cenomanian extension and basin widening was followed by Turonian compression and basin inversion. Thrusting occurred earlier than previously reported in the literature, with a vergence to the NE, at odds with the regional SW vergence of the margin.

Our study provides insight into the spatial distribution and the controlling factors of small-scale heterogeneity in sandstone media. A comprehensive physicochemical data set is provided, which may help to evaluate the degree of uncertainty that should be considered in field-scale property models.

We use a sediment core from the Gobi Desert (Ejina Basin, NW China) to illustrate the landscape history of the area. During 2.5 million years a sediment package of 223 m thickness has been accumulated. Various sediment types document that the area turned from a playa environment (shallow water environment with multiple flooding events) to an alluvial–fluvial environment after the arrival of the Heihe in the area. The river has been diverted due to tectonics.

The controls on the 20 Myr old Burdigalian transgression in the Swiss Molasse basin have been related to a reduction in sediment flux, a rise in global sea level, or tectonic processes in the adjacent Alps. Here, we readdress this problem and extract stratigraphic signals from the Upper Marine Molasse deposits in Switzerland. In conclusion, we consider rollback tectonics to be the main driving force controlling the transgression, which is related to a deepening and widening of the basin.

The Aar and Mont Blanc regions in the Alps are large granitoid massifs characterized by high topography. We analyse when these granitoids were first exhumed to the surface. We test this by tracking specific garnet grains, which are exclusively found in the granitoid massifs, in the sediments contained in the alpine foreland basin. This research ties in with ongoing debates on the timing and mechanisms of mountain building.

The dolomitized intervals of the Lower Jurassic deposits exposed in the Montagna dei Fiori Anticline (Central Apennines, Italy) have been investigated. Accordingly, two fault-related dolomitization events were recognised and interpreted as having occurred before and during the Apenninic orogeny. The analyses suggest significant involvement of evaporitic fluids in both events, most likely derived from the underlying Upper Triassic Burano Formation in the detachment level.

The formation of dolomite (CaMg(CO3)2), an abundant mineral in Earth's geological record, is still incompletely understood. We studied dolomites embedded in a 100 m thick succession of coastal alluvial clays of Triassic age in the southern Alps. Observation by light microscopy and Sr isotopes suggests that dolomites may spontaneously from concentrated evaporating seawater, in coastal ephemeral lakes or tidal flats along the western margin of the Triassic Tethys sea.

A large quantity a continental material is transported to the oceans by the world rivers. Once in the ocean, these particles can be transported down the continental shelf thanks to underwater avalanches. The repetition of such massive events can form very important sedimentary deposits at the continent–ocean transition. Data obtained during an oceanic cruise in 2010 allowed us to study such a system located offshore of Gabon and to evaluate the importance sediment transport in this area.

A newly discovered type of hydrocarbon leakage structure is investigated following the preliminary works of Ho (2013; et al. 2012, 2013, 2016): blade-shaped gas chimneys instead of classical cylindrical ones. These so-called
Linear Chimneysare hydraulic fractures caused by overpressured hydrocarbon fluids breaching cover sediments along preferential directions. These directions are dictated by anisotropic stresses induced by faulting in sediments and pre-existing salt-diapiric structures.

This study focuses on the assessment of the geothermal potential of two extensive upper Devonian aquifer systems within the Alberta Basin (Canada). Our work provides a first database on geothermal rock properties combined with detailed facies analysis (outcrop and core samples), enabling the identification of preferred zones in the reservoir and thus allowing for a more reliable reservoir prediction. This approach forms the basis for upcoming reservoir studies with a focus on 3-D modelling.

Here, we report on the formation mechanisms of a modern BIF analog in the Cape Vani sedimentary basin (CVSB) on Milos Island, Greece, demonstrating that rare environmental redox conditions, coupled to submarine hydrothermal activity and microbial processes, are required for these types of rocks to form in the modern marine biosphere.

The OPA material has been intensively studied by a variety of multiple scale and non-destructive 3-D X-ray CT investigations, following a consequent top-down approach to identify specific regions of interest. According to the mechanical experiment, it has been observed that the shear failure is located in a clay-rich area. Within the intersecting area of the two main fractures, a so called mylonitic zone with a particle reduction was observed on the open shear failure using CT and SEM techniques.

This study improves our understanding of the evolution of pores in shales for modelling transport properties. 3-D microscopy on early and postmature Posidonia Shales showed similar porosities and pore size distributions. Large isolated pore clusters are within carbonates and clay minerals. Pores form during maturation in the postmature-matrix-filling organic matter. Modelled permeabilities are lowest perpendicular to bedding. They decrease with increasing maturity and are comparable to experimental data.

State-of-the-art synchrotron x-ray imaging was used to observe micron scale transport processes in real time. The 20 Hz 3-D image acquisition rates give experimental data free from motion artefacts, and suitable for detailed quantitative analysis of the dynamic fluid distribution, flow pathways and processes. The method marks a major breakthrough in our ability to capture both sub-second and lower frequency non-equilibrium process in many geological or engineering systems.

This study investigates the experimentally induced effects of CO2 storage on underground reservoir sandstones by applying high-resolution computer tomography and standard petrophysical methods. The results of digital rock physic calculations derived from the µ-CT scans are compared with measurements achieved by the standard methods. Both approaches lead to similar results for coarse- and medium-grained sandstones but differ for fine-grained sediments.

Sedimentary beds can exhibit signs of local deformation in pyroclastic strata. Patterns are reviewed and trigger mechanisms interpreted.
During an eruption, basal granular flows can have a fluidized behavior, inducing over- or underpressure at the bed interface. Basal shear can overturn strata. Large blocks ejected ballistically deform the ground when landing. Explosions at the vent produce shock waves that can destabilize a bed. These syn-eruptive triggers are specific to explosive volcanism.
