The Dynamics of Faulting and Dyke Formation: with Applications to Britain

Abstract

THIS book can be warmly recommended to geologists, who will read it with great interest and profit. The theory of principal stresses had long been applied by engineers to explain fractures in materials, but it was the author who first applied it in explanation of the main types of rock fractures or faults well known to geologists. From field experience these had been classified into three main types called strike faults, dip faults and oblique faults which conformed to neither of these directions. With increasing knowledge it was found that the majority of those in the first class were overthrusts while those of the second class were mainly normal faults. It was only later that the oblique faults were better understood ; many of these have now been proved to be associated with some horizontal movement parallel to the earth's surface, and they have been called tear faults, transcurrent faults (the name favoured by the author), and a variety of other names.
