Webb11 apr. 2024 · Thus the fault rocks and structures within the VFZ core display evidence for at least four phases of reactivation through repeated localization along pre-existing structures and fault rocks. The earliest fault rocks are cataclasites, indurated fault gouges and pseudotachylites that are interpreted to have formed during sinistral movements … Intrusions are broadly divided into discordant intrusions, which cut across the existing structure of the country rock, and concordant intrusions that intrude parallel to existing bedding or fabric. These are further classified according to such criteria as size, evident mode of origin, or whether they are tabular in shape. … Visa mer In geology, an igneous intrusion (or intrusive body or simply intrusion ) is a body of intrusive igneous rock that forms by crystallization of magma slowly cooling below the surface of the Earth.

In most cases, a body of hot magma is less dense than the rock surrounding it, so it has a tendency to move very slowly up toward the surface.
