Pyroclastic density currents (PDCs) are mixtures of two components, namely solid particles
and fluid (gas) phase. They macroscopically behave as dense, multiphase gravity currents …

The term sediment gravity flow was introduced to describe the major flow types involved in
resedimentation processes and was defined as the flow of sediments or sediment–fluid …

Submarine sediment density flows are one of the most important processes for moving
sediment across our planet, yet they are extremely difficult to monitor directly. The speed of …

The complexity of flow and wide variety of depositional processes operating in subaqueous
density flows, combined with post‐depositional consolidation and soft‐sediment …

Now enhanced with colour photographs and illustrations, this thoroughly revised fourth
edition of Sedimentary Structures enhances its status as a major textbook in geology. Since …

Ignimbrites are vast, landscape-modifying deposits composed mainly of pumice fragments
and ash. They derive from the most. hazardous types of explosive volcanic eruptions and …

Under the prevailing turbidite paradigm, the term turbidite (ie, deposits of turbidity currents
with Newtonian rheology and turbulent state) is used very loosely and is commonly applied …

Supercritical‐flow phenomena are fairly common in modern sedimentary environments, yet
their recognition and analysis remain difficult in the stratigraphic record. This fact is …

Naturally occurring high-discharge flows of water and sediment in open channels
(ie,``floods''), vary over a wide and continuous spectrum of sediment concentration and …

Submarine gravity flows are a key process for transporting large volumes of sediment from
the continents to the deep sea. The location, volume, and character of the sediment …
