Difference in depositional behavior of hypopycnal and hyperpycnal flows in the context of continental margins
… characterized in terms of the difference between hyperpycnal and hypopycnal conditions. The former prevails when the incoming flow is denser than the water of the receiving basin; the flow plunges to the bottom of the lake and forms a bottom density flow. The latter prevails when the incoming flow …

The Effects of Basin Slope and Boundary Friction on the Character and Plunge Location of Hyperpycnal Flows Entering a Laterally Unbounded Basin
This thesis focuses on the behaviour of hyperpycnal plumes in river mouth discharges. The plunging of high density flows in two dimensional channels has been extensively studied before. A fundamental assumption in these studies is that the flow is laterally confined. These studies allow the flow to …

Thin-bedded Facies Analysis of a Ferron Storm-dominated Delta Front and Prodelta: Cretaceous Ferron Sandstone, Utah
… (tempestites), ignitive turbidity currents, or hyperpycnal flows. This study quantitatively evaluates the proportion of each facies types within heterolithic strata at the base of the sandier lithofacies to better characterize the relative proportion of formative processes. Mud along shelves has …

Taphonomy and Palaeoecology of multi-element skeleton invertebrates: a genetic model for exceptional preservation
… whose origin is related to turbidity currents(hyperpycnal flows) generated by a flood-dominated fluvio-deltaic system entering in lagoonal or protected shallow marine settings. Two taphofacies are recorded: tf1 consists of a high density of articulated remains, which constantly show convex down …

CONTRASTING PROCESSES OF DEPOSITION IN THE LATE CRETACEOUS PANTHER TONGUE SANDSTONE OF CENTRAL UTAH: THE ROLE OF AUTOGENIC VERSUS ALLOGENIC PROCESSES, AND THE IMPORTANCE OF HYPERPYCNAL FLOW
… system that could produce relatively frequent hyperpycnal flows. Typical characteristics would have included short and steep river systems that have a significant sediment load, aligning with previous interpretations of hyperpycnite-dominated deposits in Panther Tongue outcrops. The rarity of …

Cyclically-Forced Hyperpycnites of the Ancient Colorado River Proximal Prodelta
… of the rhythmites was accomplished via hyperpycnal flows, each couplet likely representing one event in a setting characterized by high overall depositional rates. Time series analysis performed on bed thickness of 265 measured couplets obtained a prominent spectral peak above the 99% …
