Disconnected submarine lobes as a record of stepped slope evolution over multiple sea-level cycles [PDF]
Geosphere, 2018 The effects of abrupt changes in slope angle and orientation on turbidity current behavior have been investigated in numerous physical and numerical experiments and examined in outcrop, subsurface, and modern systems.

The influence of basin setting and turbidity current properties on the dimensions of submarine lobe elements [PDF]
Sedimentology, 2020 Submarine lobes have been identified within various deep‐water settings, including the basin‐floor, the base of slope and the continental slope. Their dimensions and geometries are postulated to be controlled by the topographic configuration of the ...

Submarine lobe deposits of the Point Loma Formation, California: Quantifying event‐bed architecture and lateral heterogeneity [PDF]
The Depositional Record, 2021 Over the last several years, numerous outcrop localities have been revisited to add quantitative detail to submarine lobe facies models that previously focussed on facies relationships in a qualitative sense.

Sediment Volume and Grain-Size Partitioning Between Submarine Channel−Levee Systems and Lobes: An Experimental Study [PDF]
Journal of Sedimentary Research, 2018 The width and depth of submarine channels change progressively as the channels evolve. This is inferred to act as an important control on the rate of sediment loss due overbank and in-channel deposition.

Fill, flush or shuffle: How is sediment carried through submarine channels to build lobes?
Earth and Planetary Science Letters, 2022 Submarine channels are the primary conduits for land-derived material, including organic carbon, pollutants, and nutrients, into the deep-sea. The flows (turbidity currents) that traverse these systems can pose hazards to seafloor infrastructure such as cables and pipelines.

McHargue et al Architectural Diversity of Submarine Lobes
, 2019 The most popular model for submarine unconfined lobate deposits has the following attributes: (1) a single feeder channel that delivers sediment, (2) a set of distributary channels present only in the proximal part of the lobate body, and (3) unchannelized tabular deposits present in the middle and distal part of the lobate deposit.

Dimensions and architecture of late Pleistocene submarine lobes off the northern margin of East Corsica [PDF]
Sedimentology, 2008 AbstractSandy lobe deposits on submarine fans are sensitive recorders of the types of sediment gravity flows supplied to a basin and are economically important as hydrocarbon reservoirs. This study investigates the causes of variability in 20 lobes in small late Pleistocene submarine fans off East Corsica.

Sedimentology, Stratigraphic Architecture, and Depositional Context of Submarine Frontal-Lobe Complexes [PDF]
Journal of Sedimentary Research, 2014 Copyright © 2014, SEPM (Society for Sedimentary Geology).Frontal lobes develop during discrete periods of progradation in deep-water systems, and commonly form on the lower slope to base of slope. In reflection seismic datasets, they are identified as high-amplitude reflectors that are cut as the feeder channel lengthens.

Autogenic controls on hybrid bed distribution in submarine lobe complexes [PDF]
Marine and Petroleum Geology, 2017 Hybrid beds, the deposits of sediment gravity flows that show evidence for more than one flow regime (turbulent, transitional and/or laminar), have been recognized as important components of submarine lobe deposits. A wide range of hybrid bed types have been documented, however, quantitative analysis of the stratigraphic and geographic distribution of ...
