Current Research (Cont.) Martinez Major NSF
initia- tives such as the Ridge2000 Program
have 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.

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.

Future Directions Hey in addition to continuing
my research in the 3 areas mentioned above, I'm
revising the Cox and Hart textbook, Plate
Tectonics How it Works. Martinez Studies of
several (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
expand 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).
