Description

Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 175.

A Continental Plate Boundary
offers in one place the most comprehensive, up-to-date knowledge for researchers and students to learn about the tectonics and plate dynamics of the Pacific-Australian continental plate boundary in South Island and about the application of modern geological and geophysical methods. It examines what happens when convergence and translation occur at a plate boundary by
  • Describing the geological and geophysical signature of a continental transform fault;
  • Identifying the diverse vertical and lateral patterns of deformation at the plate boundary;
  • Assessing an apparent seismicity gap on the plate boundary fault and fast-moving plate motions;
  • Comparing this plate boundary to other global convergent continental strike-slip plate boundaries;
  • Documenting the utility of the double-sided, onshore-offshore seismic method for exploration of a narrow continental island; and
  • Providing additional papers presenting previously unpublished results.

This volume will prove invaluable for seismologists, tectonophysicists, geodesists and potential-field geophysicists, geologists, geodynamicists, and students of the deformation of tectonic plates.
