Current Research Hey Analysis of data from
recent oceanographic expeditions
a) Tectonic/volcanic segmentation and contr
ols on hydrothermal venting along Earth's faste
st sea- floor spreading system, EPR 27-32S
b) ALVIN magnetometer investi- gations of
tectonic windows into superfast spread crust ex
posed at Pito Deep, Easter Microplate
c) Origin of the V-shaped ridges along the Rey
kjanes Ridge south of Iceland (see Fig.)
Current Research (Cont.) Martinez Major NSF i
nitia- tives such as the Ridge2000 Program ha
ve decadal time spans with goals
of investigating a broad range of
interrelated processes at seafloor
spreading centers from mantle pro-
cesses to the magmatic and tectonic
construction of the oceanic crust to
the biological systems that live in
these settings. Hydrothermal activity
is a key process that transfers matter
and energy across these components.
My recent work has focused on the
study of the geologic and geophysical
controls on the occurrence and distri-
bution of hydrothermal activity at back-
arc spreading centers.
Evolution of mantle mineralogy/textures and an
isotropy 08
Current Research (Cont.) Fryer Divergent
(Mid-Atlantic Ridge IODP Exp 305 and Mariana
Backarc Basin) and convergent plate margin
processes, (Mariana forearc) petrogenesis and
metamorphism of the mantle, changing stress
regimes in subduction zones. Recently funded to
examine dredged serpentinized peridotite samples
from numerous forearc sites to study evolution of
the suprasubduction-zone mantle.

subduction, hot-spot mapping. Reconciling late

Wessel et al., 2006 Geometry of the
Hawaii-Emperor seamount chain. The Hawaii-Emperor
Bend dated at 4748 Myr (Chron 21) by allowing
12 Myr for edifice construction. Triangles
recent dates from Sharp and Clague 2002 except
for Nintoku Tarduno et al., 2003.
Future Directions Hey in addition to continuin
g my research in the 3 areas mentioned above, I'm
revising the Cox and Hart textbook, Plate
Tectonics How it Works. Martinez Studies of s
everal (Lau, Manus and Mariana) backarc basins
reveal a broad range of conditions of back-arc
basin development. His work has attracted
attention from major mining companies (Teck
Cominco, Nautilus Minerals - currently funding my
research though sizable gifts (700K) I hope to
continue and expand this academic/industry
relationship in the future. Kroenke Will expa
nd recent studies to include examination of
global tectonism, cause and effect.
  • Future Directions (Cont.)
  • Fryer Studies of arc/backarc basin volcanism
    has been carried out recently in collaboration
    with Japanese colleagues (Shinkai 6500 diving and
    dredging cruises). Studies of origin of island
    arc crust will continue also with Shinkai 6500
    dives. Recently funded studies of effects of in
    situ Archeal communities on peridotitic
    substrates will be carried out at ODP Seafloor
    Observatory Site 1200. I will be Co-chief
    Scientist and first user of WHOI HROV in the
    Mariana Trench (2009). A recently funded study
    of the evolution and regional variability of
    forearc mantle will use dredged samples of
    serpentinized peridotites from the Mariana
    forearc (analysis to include thermal IR,
    mineralogy, micro-Raman mapping, EBSD analysis,
    velocity measurements). I am principal proponent
    (approached to be Co-chief Scientist) of IODP
    drilling expedition to Mariana region in 2009
    (scheduled/funding permitting).
