Abstract: Density and Distribution of Microfractures in Sandstones: Importance to Diagenesis

Summary

Systematic, quantitative measurements of quartz-lined micro-fractures in more than 20 siliciclastic units show that these structures are ubiquitous in quartz-cemented rocks. Theories of quartz-cement development need to take these features into account because they imply that quartz cementation is associated with fluid flow and high pore-fluid pressure.
