Deposits of pyroclastic mass flows at Bibby Hill (Pliocene, James Ross Island, Antarctica)
, 2014 Sedimentological study of the southern slopes of Bibby Hill (relic of a Pliocene tuff cone) allows recognition of twelve lithofacies and three facies associations.

, 1980 Theoretical models of debris flow emplacement suggest that some types of pyroclastic flow can move into and maintain their integrity underwater. These subaqueous flows can be emplaced at high temperature, cooling only tens of degrees centigrade.

Processes and deposits of submarine sediment density flows within the Moroccan turbidite system, offshore NW Africa [PDF]
, 2012 Submarine sediment density flows are a major process for transporting sediment from the continental shelf to the deep-ocean. Understanding submarine flow dynamics relies upon analysis of their deposits (beds) because monitoring them directly is difficult.

The fluidization behaviour of ignimbrite at high temperature and with mechanical agitation
, 2004 Experiments were carried out to study the fluidization behaviour of ignimbrite at high temperature and while being mechanically agitated. Geldart group C behaviour occurs up to 565 degreesC when the material is subjected to increasing gas flow ( without ...

Application of dimensional analysis technique to grading processes in pyroclastic flows
, 1996 The dimensional analysis technique is applied to specific aspects of pyroclastic flow transport and deposition, and particularly to the grading processes of lithic and pumice clasts in moving pyroclastic flows.

Aspects of pyroclastic flow movement and emplacement [PDF]
, 1992 Pyroclastic flows are products of explosive volcanic eruptions. Composed of hot gas and particulates, they move as ground hugging density currents. This study utilized comparisons with similar geologic phenomena (e.g.

The flow and depositional mechanisms of granular matter : experimental and field studies with implications for pyroclastic flows [PDF]
, 2006 This Doctorial Thesis investigates the fundamental problem of flow and deposition processes of unsteady, inertial flows of granular media and elucidates its implications for the behaviour of pyroclastic flows formed in explosive volcanic eruptions.

Debris Fan Produced by Failure of Canyon-Blocking Pyroclastic Flows
Ash-rich pyroclastic flows from the cataclysmic eruption of Mount Mazama (~7700 yr. B. P.), Cascade volcanic arc, Oregon, entered and blocked the narrow, bedrock-lined canyon of the Williamson River approximately 35 to 44 km from the source volcano.

, 2007 International audienceRecognition that the Fisher Tuff (Unimak Island, Alaska) was deposited on the leeside of ~500-700 m high mountain range (Tugamak Range) more than 10 km away from its source played a major role in defining pyroclastic flows as ...
