Marcasite at the Permian‐Triassic Transition
Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Distinguishing between Deep-Water Sediment Facies: Turbidites, Contourites and Hemipelagites
The distinction between turbidites, contourites and hemipelagites in modern and ancient deep-water systems has long been a matter of controversy. This is partly because the processes themselves show a degree of overlap as part of a continuum, so that the

Stratigraphy of the central parts of the Palaeoproterozoic Tampere Schist Belt, southern Finland: review and revision [PDF]
The arc-type Palaeoproterozoic volcanic-sedimentary Tampere Schist Belt (TSB), close to the centre of the Svecofennian Orogen, comprises an E-W-striking major synform in its central parts.

Linear-stability analysis of plane beds under flows with suspended loads [PDF]
Plane beds develop under flows in fluvial and marine environments; they are recorded as parallel lamination in sandstone beds, such as those found in turbidites.

Scours, and scour fields, are common features on the modern seafloor of deep-marine systems, particularly downstream of submarine channels, and in channel-lobe-transition-zones.

Grain-Size Analysis of Ancient Deep-Marine Sediments Using Laser Diffraction
Grain-size analysis of siliciclastic sedimentary rocks provides critical information for interpreting flow dynamics and depositional environments in sedimentary systems and for analysing reservoir quality of sandstone.

Supercycle in great earthquake recurrence along the Japan Trench over the last 4000 years
On the landward slope of the Japan Trench, the mid-slope terrace (MST) is located at a depth of 4000–6000 m. Two piston cores from the MST were analyzed to assess the applicability of the MST for turbidite paleoseismology and to find out reliable ...
