However, they are no more illegitimate than the geophysicist's similar answer to the similar question.
Ask a geophysicist about "geological causation" and you will be told about tectonic plates and flows of undersea lava and so forth.
Creative sedimentary geophysicists will get little technical advice or inspiration from this book, nor should it compete strongly for scarce library funds.
These are fundamental questions which should be of interest to geodynamicists, solid earth geophysicists and structural geologists.
Particularly impressive is the interaction between field structural geologists and igneous petrologists studying ophiolites in the field, with marine geologists and geophysicists.
Seismic data are too often considered the domain of the geophysicist.
Thc incorporation of these and other effects into more complex models will provide challenges in the future for both fluid-dynamicists and geophysicists.
For the geophysicist, these include nuclear magnetic resonance imaging for the investigation of microstructure, and electromagnetic induction methods and autonomous underwater vehicles for measuring sea-ice thickness distribution.
