Programme
Monday October 25th, 2010
The Geohydrologic Cycle (Bodnar: 2 hours) (Time: 9.00 - 11.00)
The whole Earth system can be divided into the following reservoirs for H2O:
atmosphere, biosphere, oceans, surface water, groundwater, glaciers and
polar ice, continental crust, oceanic crust, upper mantle, transition zone,
lower mantle and core. The amount of H2O contained in each of these
reservoirs will be discussed, as well as the fluxes of H2O between
reservoirs and residence times for H2O in the different reservoirs.
Introduction to fluid inclusions and fluid phase equilibria (Bodnar: 5
hours) (Time: 11.00 13.00 and 15.00 18.00)
Identification, analysis and application of fluid inclusions to geologic
problems.

Fluids in near-surface environments, including sedimentary basins and
Mississippi Valley-type deposits (Bodnar: 1 hour) (Time: 9.00 10.00)
As sediments are deposited and compacted during basin evolution, fluids of
varying composition are generated and expelled from sediments during
diagenesis. The compositions of fluids in sedimentary basins and origin of
basinal brines will be discussed.
Deep Crust and Upper Mantle Metamorphic and Mantle Fluids (Bodnar: 1 hour)
(Time: 10.00 11.00)
The compositions of metamorphic and mantle fluids show distinct and
systematic variations as a function of metamorphic grade and host rock
composition. Most metamorphic and mantle fluids are reasonably well
approximated by the COH system, and the fluid speciation is controlled by
the oxygen fugacity.
The Role of Fluids in Deformation and Geophysics (Bodnar: 1 hour) (Time:
11.00 12.00)
The strength of minerals and rocks varies as a function of the amount of
water present. The role of H2O in rock deformation will be discussed, as
well as geophysical techniques for identifying the presence of water in the
crust.
Fluids in magmatic hydrothermal ore deposits (Bodnar: 1 hour) (Time: 12.00
13.00)
Fluids in magmatic hydrothermal systems transport and deposit metals to
generate economic mineral deposits. Our current understanding of the role of
fluids in the ore forming process in orogenic lode gold deposits, porphyry
copper deposits, and epithermal precious metals deposits will be summarized.
Introduction to Melt inclusions (Danyushevsky: 3 hours) (Time: 15.00
18.00)
Melt inclusions are small portions of melt trapped by crystals growing
during magma evolution, and thus can represent ‘snapshot’ of the conditions
that existed during crystallisation. In this lecture, trapping mechanisms of
melt inclusions, their post-entrapment modifications, and experimental
studies of melt inclusions will be discussed.

Using melt inclusions to constrain the origin of phenocrysts in
strongly-phyric volcanic rocks (Danyushevsky: 1 hour) (Time: 9.00 10.00)
An important implication of melt inclusions is to assess whether crystals in
volcanic rocks crystallised from the same magma type as represented by the
transporting melt (i.e., the groundmass of the rock), or are xenocrysts.
Different examples from sudbuction-related volcanic suites will be shown.
Timing crystallisation processes using melt inclusions; Using melt
inclusions to determine komatiite melt compositions; Melt inclusion studies
on Vesuvius (Danyushevsky: 2 hours) (Time: 10.00 12.00)
Post-entrapment re-equilibration of melt inclusions with their hosts can be
used to assess crystallisation rates of individual phenocrysts. Melt
inclusions can be a powerful tool for recovering melt compositions in
ancient volcanic suites, when the groundmass in the lavas is chemically
modified by alteration. A summary of melt inclusion studies of Vesuvius will
be presented.
Thermodynamics and Physics of Melt-Fluid ± Mineral Systems (Webster: 4
hours) (Time: 12.00 13.00 and 15.00 18.00)
Volatile components in silicate melts influence melting temperatures and
melt viscosity. Volatile components also influence the stability of
minerals and fluids and consequently control larger processes including
magma rheology and explosivity. The role of H2O and CO2 in these processes
will be discussed.
