After finally solving a long lasting administrative problem the IAVCEI field
trips are now listed on the IUGG 2007 web page as of Jan 31, 2007.
The web site is http://www.iugg2007perugia.it/
The list is also included below for your information.
Please note the following. The deadline for abstracts is February 28. Note that
the entire IAVCEI portion of the IUGG meeting will be the second week, July
9-13, therefore most field trips will be post conference. However it is possible
to have trips before the second week of the IUGG conference, such as July 5-8 if
this is the only option.
If you are interested in attending a field trip, please contact the field trip
leaders directly as well as filling out the forms for IUGG. This way by the end
of February we will have a good idea of how many people are interested in each
field trip.

Volcanic activity at Mount Etna
Mount Etna, one of the largest active volcanoes in the Mediterrannean area and
in Europe, shows peculiar petrologic and geochemical features, related to a very
complex structural setting. Its activity is at the base of myths and legends
from classic times and records of its eruptions date back to some centuries b.C.
The volcano is located in a densely populated area, at the boundary between a
thinned crust domain (Ionian Sea) and a continental crust one (Sicily), where
large regional fault systems intersect each other, next to the front of the
south-verging overthrust pile of the Apennine-Maghrebian mountain range. Its
products range from basal tholeiites to members of a Na-alkaline series (mostly
hawaiites – mugearites), thet show evidence for an imprint from a calcalkaline
component. The volcanic sequence is composed of lava flows, air-fall and
(scarse) pyroclastic flow deposits, lahars, erupted by distinct volcanic
centres. The field trip is aimed at giving the opportunity of discussing on the
diverse parameters that control the volcanological and petrological features of
the volcano, and on hazard related problems.

Pyroclastic products of the quaternary age in central Italy: Ignimibritic
deposits and related calderas
The field trip will provide participants an opportunity to examine some of the
most studied pyroclastic flow deposits in the world in their most significant
exposures. The field trip will cover two important volcanic districts in
central Italy: the Vulsini and Vico Volcanic Districts, which belong to the
Roman Comagmatic Province. The planned itinerary will enable partecipants to
observe pyroclastic flow deposits which are characterized by a broad spectrum of
peculiar features in terms of composition, component distribution, grain-size,
degree of welding, structures, depositional sequences, geometries and their
relationships to eruptive and depositional mechanisms and to observe the related
calderas. One of the main goal is to stimulate discussions on the mechanisms
developed during the respective transport and depositional phases .

Calderas types and Ignimbrite types
We propose a 5 days field workshop on the calderas and ignimbrites of the Colli
Albani, Roccamonfina, and Vico volcanoes, along the Tyrrhenian margin. The
volcanoes diplay a full spectrum of ignimbrite types and caldera types, from
piecemeal, to downsag, to lateral sector collapse, with excellent morphologies
and outcrops. The workshop will focus on the volcanotectonics of collapses and
the facies relationships of ignimbrites as a clue into the evolution of the
plumbing system. A main focus will be the quiescent Colli Albani volcano, where
the caldera shows a polyphase history from piecemeal to downsag and excellent
esposures of both the volcanotectonic deformations and the ignimbrites. The
presence of a continuous peri-calderic fissure-related ridge of spatter and lava
ramparts is an almost unique surface expression of a ring-dyke complex.
Furthermore the workshop will discuss the origin of the explosivity of the
mostly K-foiditic Colli Albani magma, its present status, the pre-historical and
historical volcanic and peri-volcanic activity and the influnces on the birth
and growth of the city of Roma.

Volcanic History of Nisyros Island (Greece)
The field trip is focused on the volcanic history of Nisyros. Nisyros (one of
the Dodecanese island, near the Turkish cost) is a nice, fully volcanic, island
topped by a summit caldera of 4 km of diameter. Inside the caldera we will visit
spectacular phreatic craters and related debris flows deposits produced by
numerous hydrothermal explosions during historic times and debate on the
characteristics of the related geothermal system. The today’s caldera is the
result of a number of explosive eruptions; we will see as the present caldera
morphology is controlled by major tectonic trends that determined in the same
way the dikes emplacement and the vent distribution on all the island. The
epiclastic and submarine deposits we will see mark important episodes of the
volcano life as well as the presence of a debris avalanche deposits widespread
in the northern, horse-shaped, sector of the island.

Facies and depositional mechanisms of the Aeolian pyroclasts and lavas as a tool
for the evaluation of volcanic hazard
The five days field trip will mainly focus on the detailed analysis of the
structural and textural features of the Aeolian pyroclasts and lavas, with the
aim of acknowledging the processes governing the eruptive activity. The deposits
of low-medium energy eruptive dynamics of acid and basic magmas (strombolian,
surtseyan and vulcanian) that characterize the younger explosive eruptions of
the Aeolian volcanoes will be analyzed in detail. The wide variability of
pyroclastic deposits that are present in Stromboli, Vulcano and Lipari, and the
broad compositional spectrum of emitted products, offer the possibility to
analyze the depositional facies of a adequate number of eruptions. Particular
emphasis will be given to the reconstruction of the transportation and
emplacement mechanisms of pyroclastic deposits. For some well documented
eruptive sequence, the quantitative assessment of hazard will be proposed.

Monte Vulture Volcano (Basilicata) and the Umbria and Latium Italian extrusive
carbonatites
The trip will focus on the volcanic history of Monte Vulture, 400 km south of
Perugia. We will spend three days looking at the deposits of this relatively
small apparatus characterized by alternating phase of building and disruption
and by a notable, tectonically controlled, scattering of volcanic vents and
variable eruptive styles. The final stadium of Vulture activity ended at 130-140
ka bp, and is characterized by a swarm of diatremic structures that produced
melilite bearing rocks and extrusive carbonatites, with abundant peridotitic
nodules. A number of others intrusions, diatremes and volcanic centers (San
Venanzo, Colle Fabbri, Polino, Cupaello and Oricola) composed by
melilite-bearing rocks, including kamafugites and extrusive carbonatites, are
scattered along the Appennine and we will visit them during the first two days
of the field trip, along the road for approaching Monte Vulture .

Neapolitan volcanoes: Vesuvius and Campi Flegrei
This field trip will be devoted to the illustration of the volcanic and
deformational history of the active Neapolitan volcanoes (Somma-Vesuvio, Campi
Flegrei, Ischia), and the evolution and present state of their magmatic feeding
systems. The trip will give the opportunity to visit various types of volcanoes
such as stratovolcano (Somma-Vesuvio) and caldera (Campi Flegrei, Ischia).
Sedimentological, textural and structural features of the rocks as well as the
petrological signature of the erupted magmas will be presented and discussed in
order to infer the characteristics of the eruptions and their relationships with
magma withdrawal dynamics. All three active volcanoes have erupted in historical
times and have deeply influenced the life of the inhabitants of the regions.
Therefore the trip will go through archaeological, historical and artistic
testimonies of such a relationship. The Pompeii and Herculaneum excavations are
known world-wide. Other aspects on which we will focus are volcanic hazards and
risk, and mitigation actions for volcanic crisis preparedness and management. In
particular, the current criteria used for preparing the hazard maps of these
volcanoes will be illustrated and discussed.
General information: 4 days; departure and arrival point is Napoli; travel by
bus and boat; the degree of physical effort is low; weather will be dry and
warm.

Volcanic and plutonic association in the Miocene-Pliocene Tuscan Magmatic
Province
Plutonism and Volcanism in the Tuscan Magmatic Province (Central Italy)
The Tuscan Magmatic Province is an outstanding natural laboratory for
understanding geological and structural features related to the emplacement
of plutonic and volcanic complexes, and to study dynamical and geochemical
mechanisms acting during magma interaction.
The aim of the field trip is to provide a crustal section through the
Miocene-Pliocene intrusive complexes and the Pliocene-Pleistocene volcanic
rocks of the Tuscan Magmatic Province. It will be focused on magmatic
structures in granitic rocks and origin of pluton zonation, magma
emplacement in the shallow crust, enclaves and magma mixing/mingling in
granitoid and volcanic rocks, compositional diversity of magmatism versus
source rocks, crustal melting and origin of silicic melts. The variability
of mantle- and crust-derived magmas coexisting in space and time in the
Tuscan Magmatic Province will provide the basis for deep discussions about
possible end-members involved in the interaction processes, also in
relationship with the geodynamic style of the region from Miocene to
Recent.
The field trip is organized starting with an excursion on monzogranites of
Monte Capanne (Island of Elba), continuing with volcanic rocks cropping out
in the area of San Vincenzo and Roccastrada, and then focusing the last
part of the field trip on volcanic rocks cropping out in the area of Amiata
and Radicofani.
Duration: 3 full days plus travel time from Perugia to South Tuscany

Phreatomagmatic volcanic field in a Mio/Pliocene lacustrine basin: Pannonian
Basin
The volcanic erosion remnants in the Pannonian Basin are grouped into volcanic
fields such as the Bakony- Balaton Highland, Little Hungarian Plain, Burgenland-
Slovenian and Southern-Slovakian Volcanic Field. These volcanic fields were
active in late Miocene to Quaternary time and are located in the territory of
Hungary, Austria, Slovenia and Slovakia. The five day lasting field trip will
lead to volcanic remnants of these volcanic fields which are built up by around
at least 100 alkaline basaltic eruptive centers as variable eroded scoria cones,
tuff rings, maars, maar volcanic complexes, shield volcanoes, mesa flows and
shallow subsurface intrusive complexes (dykes and sills). The field trip gives a
detailed view into the architecture from the root zones to the unmodified
landforms of phreatomagmatic volcanoes. Also the different structures due to the
influence of water availabiliy during eruption can be observed at different
sites. Here the basic characteristics of the volcanology of the volcanic fields
in the Pannonian Basin is given on the basis of a general review of the past
researches as well as the results of ongoing physical volcanological researches
in the region. It is demonstrated that the distribution of volcanoes in the
Pannonian Basin is structurally controlled by old structural elements in the old
pre-volcanic rock units. The geographical distribution of different types of
vents such as phreatomagmatic versus magmatic vents are in relationship with the
general hydrogeological characterisitcs of the pre-volcanic rock units.
