TECTONlCS AND PHYSICS Geology, although rooted in the laws of
physics, rarely has been taught in a manner designed to stress the
relations between the laws and theorems of physics and the
postulates of geology. The same is true of geophysics, whose
specialties (seismology, gravimetIy, magnetics, magnetotellurics)
deal only with the laws that govern them, and not with those that
govern geology's postulates. The branch of geology and geophysics
called tectonophysics is not a formalized discipline or
subdiscipline, and, therefore, has no formal laws or theorems of
its own. Although many recent books claim to be textbooks in
tectonophysics, they are not; they are books designed to explain
one hypothesis, just as the present book is designed to explain one
hypothesis. The textbook that comes closest to being a textbook of
tectonophysics is Peter 1. Wyllie's (1971) book, The Dynamic Earth.
Teachers, students, and practitioners of geology since the very
beginning of earth science teaching have avoided the development of
a rigorous (but not rigid) scientific approach to tectonics,
largely because we earth scientists have not fully understood the
origin of the features with which we are dealing. This fact is not
at all surprising when one considers that the database for
hypotheses and theories of tectonics, particularly before 1960, has
been limited to a small part of the exposed land area on the
Earth's surface."
