IAS meeting - Call for abstracts - Transport and sedimentation of pyroclasts by and in water
************************************************************************************************
Dear
Colleagues,
We would like to draw your attention to a session on Transport
and
sedimentation of pyroclasts by and in water at the 2014
IAS meeting, the
International Association of Sedimentologists. The conference
will be held the
18-22 August 2014 in Geneva, Switzerland.
Session convenors: Martin Jutzeler (National Oceanography
Centre, Southampton,
UK) and Vern Manville (University of Leeds, UK).
Session
description:
Volcanic
systems are amongst the most complex depositional environments
on Earth, where
the diversity of eruption styles and magnitudes influences the
nature, volume
and dispersal of the pyroclastic material and topography
produced, all
superimposed on the characteristics of the receiving
environment, whether
terrestrial or marine. Episodic eruptions can overwhelm existing
sediment
transport and depositional systems resulting in complex facies
successions that
evolve spatially and temporally, with large volumes of
pyroclasts ending up in
oceans or lakes, either directly from primary explosive
eruptions in the form
of pyroclastic flows and tephra fall, or from resedimentation
events such as
lahars and volcanogenic floods. Less well-known and even less
well-understood
subaqueous explosive eruptions can introduce volumes of
pyroclastic detritus
equivalent to their subaerial counterparts directly into the
marine or
lacustrine realm. In subaqueous volcanic settings
resedimentation events are
common, occur on the smallest slope gradients and can be
triggered by
earthquakes, water column disturbances of various sorts, or
seafloor processes.
We seek contributions on facies characterization of
volcaniclastic
accumulations through study of uplifted stratigraphic
successions, submarine sampling,
geophysical exploration, and micro-textural analysis of single
particles. The
emphases of this session encompass the reconstruction of source
environment,
eruption style, transport and depositional process. Case studies
on risk
mitigation are also welcome.
The abstract
submission deadline is April 30, 2014. Full details can
be

Hope to see you in Geneva!
