Comments on progress in understanding brittle rock fracture and chemical change
Structural geology emerged as an applied geoscience discipline providing predictive tools in economic geology. Through the subsequent development of quantitative approaches and in conjunction with compositional and isotopic analytical tools, these techniques have provided fundamental insight into deformation processes that shaped our current understanding of global tectonic and planetary processes. A more recent development within…
A new model accounts for crystal growth patterns and internal textures in quartz cement in sandstone fractures, including massive sealing deposits, thin rinds or veneers that line open fracture surfaces, and bridge structures that span otherwise open fractures. High-resolution cathodoluminescence imaging of bridge structures and massive sealing deposits indicates that they form in association with…
