Neville Price presents a major breakthrough in our understanding of
the subject of plate tectonics in this new book. In this ambitious
look at the importance of impacts of objects from space on the
earth, he challenges the fundamentals of the theory on which
geoscience has rested for the past 25 years.

In the latter half of the 20th century, earth-scientists gradually
became aware of the scale and effect of bombardment by meteoric
material on Earth. Prior to 1950 only a handful of small craters
were generally accepted as resulting from impact events. Now
"certain" impacts number around 150, with four such features
measuring over 100km in diameter.

Neville Price evaluates the mechanisms that give rise to plate
movements. Generally, such plates move slowly at about the
rate-of-growth of human nails and their tracks are usually smooth,
gentle curves . Major Impacts and Plate Tectonics presents evidence
to show that impacts can cause significant and dramatic changes in
track, which cannot be explained by current theories of plate
tectonics. The book also demonstrates that such major impact events
often coincide with the development of continental flood basalts
and oceanic plateau basalts and frequently coincide with major
stratigraphic stage boundaries and toxicity, which in turn can be
associated with periods of extinction. It concludes that geological
history comprises periods of relatively orderly, evolutionary
change in Earth and life-forms punctuated by catastrophic changes
induced by major impacts that reset the evolutionary clock.
