structural and microstructural data will provide insight into the roles
of faulting and fracturing during crustal accretion and evolution of
the oceanic crust, especially at the boundary between volcanics and

Paris, working with Dr. Yohan Guyodo.
"Since I remember I've been always fascinated by the curious and
almost incredible opportunity to observe on land, or even on rugged
mountains, what was long before formed on the ocean floor: the
ophiolites. These rocks contain the history of planet Earth and
express all its strength. The InterRidge Fellowship gives me the
opportunity to study and compare the ocean relict, still preserved in
the ophiolites, with present day seafloor rocks. Somehow, it will be
like bringing back these old rocks, which have been travelling for a
long time, to their original environment”.
Alessio Sanfilippo
Sanfilippo is studying the
petrological processes
controlling the first
phases of generation of
the lower oceanic crust,
tracking the minerals’
chemical evolution from
the mantle to the
primitive gabbroic rocks,
together with Prof. R.
Tribuzio and Dr. M.
Tiepolo at the University
of Pavia. Sanfilippo will
take part in a scientific
cruise to the Mid Atlantic
Ridge and he will work
with Dr. Henry Dick at the Woods Hole Oceanographic Institution,
USA. His proposal is entitled: "The role of the melt supply
variability in the development of a detachment fault system”.
"I have always been attracted by the complexity of the geological
processes constraining the formation of the oceanic crust at
spreading ridges. The detachment faults are an important
component of lithospheric creation along oceanic ridges and
provide windows into the oceanic lithosphere. The InterRidge
Fellowship will enable me to take part in a research cruise to study
the role of magmatism in the development of a detachment faulting
system at the Mid Atlantic Ridge. I am excited by the possibility of
sampling portions of the lower oceanic crust and mantle,
constraining the deep processes that generate the detachment
faulting".
Jessica Till
Till received her PhD from the University of Minnesota in 2011 and
has participated in an IODP drilling expedition to sample lower
crustal rocks in superfast spreading crust. She will visit Imperial
College, London, UK to work with Dr. Adrian Muxworthy on her
Fellowship proposal: "Quantification of Fe-oxide exsolution
microtextures in silicates to constrain cooling history at a superfast
“The lower oceanic crust is an exciting frontier in ocean research
and the microscopic Fe-oxide mineral intergrowths that occur
throughout the lower crust have interested me for years. The
InterRidge fellowship gives me a great opportunity to investigate
the origins of this intriguing mineralogical system. Their textures
could provide a wealth of information about magma emplacement
mechanisms and thermal history at ocean ridges".

Hanchao Jian
Hanchao Jian will work on full-waveform inversion of 3D seismic
data collected at the ultra-slow spreading Southwest Indian Ridge,
which is the first 3D seismic experiment conducted over an ultraslow
spreading ridge. This is part of a Sino-French joint project,
where 40 Chinese and French ocean bottom seismographs were
deployed for a 3D active-source OBS experiment on Chinese R/V
“Dayang Yihao” in March 2010. He is going to work at IPGP on the
analysis of the 3D seismic data and will be jointly supervised by
Prof. Satish Singh (seismologist) at IPGP and Prof. Y. John Chen
(geodynamicist) at Peking University.
"I am interested in the seismic and geodynamic study of mid-ocean
ridges (MORs). The IR/ISA fellowship will give me an opportunity
to investigate the detailed seismic structure and geodynamic
