Abstract

In this paper we utilize the principles of linear elastic fracture mechanics (LEFM), and examine the formation and stability of a system of parallel cracks under a combination of bending and hydrostatic compression, as a possible mechanism for the formation of steeply dipping joint sets. In particular, we develop relationships between the length and spacing of joints, in response to changes in tectonic stresses and strains, and changes in rock fracture toughness. Our results indicate closer joint spacing in rocks with a lower fracture toughness, and wider joint spacing in joints formed at deeper depths. Both of these findings are supported by field observations. (Author abstract. )
