G. Roult et D. Rouland, ANTARCTICA-I - DEEP-STRUCTURE INVESTIGATIONS INFERRED FROM SEISMOLOGY- A REVIEW, Physics of the earth and planetary interiors, 84(1-4), 1994, pp. 15-32
The strategic position of Antarctica and its role have always been see
n as clues to the tectonic and geodynamic history of the southern hemi
sphere. Direct investigations are difficult, and seismology was, and s
till is, a very efficient tool for answering some important questions.
Major seismological results from the beginning of the century to the
present are reviewed, taking into consideration their limitations owin
g to the lack of stations and data. The existing regional Earth models
reviewed are very simple because of poor processing facilities. The a
vailability of high-quality data, obtained with the GEOSCOPE network i
n this part of the southern hemisphere, has recently led to the constr
uction of maps of lateral heterogeneities of Antarctica with an improv
ed resolution. A brief report of our contribution is presented.
