Chemical processes in deformation at low metamorphic grades: pressure solution and hydraulic fracturing.

Abstract

The most common pressure solution structures, such as stylolites in limestones, clearly evolve through complex chemical processes, as do cleavage stripes and associated syntectonic veins which are abundant in terrigenous sedimentary rocks that have been deformed under low grade metamorphic conditions. This review focusses on stripes and veins, drawing together those concepts that need integrated study in order to reach a better understanding of pressure solution.-from Author
