This book … reevaluates the concept of uniformitarianism
based only on events and processes familiar in human
experience and makes it clear that a
radical expansion of that concept is needed to account for
striking discontinuities in geology, paleontology and
climatology. The contributors demonstrate that
modern geology … has developed to the point where the
consideration of catastrophes … offers insight rather
than confusion.

The Earth’s crust bears
decisive evidence of
ancient catastrophic
processes which have
operated on a regional
and global scale.
This book is a
compendium of geologic
literature challenging
the notion that the
Earth slowly evolved to
its present
configuration.
