Chemistry and fracture pattern development

A review of the role of chemistry in fracture pattern development and of prospects for future research was recently published in Reviews of Geophysics.

As a prestigious review publication by invitation only, Reviews of Geophysics provides a comprehensive overview of geophysics research.

Fracture pattern

Fracture pattern development has been a challenging area of research in the earth sciences for more than 100 years. Much has been learned about the spatial and temporal complexity inherent to these systems but severe challenges remain. The article in Reviews of Geophysics describes how future advances will require new approaches based on a chemical perspective.

Chemical processes play a larger role in opening-mode fracture pattern development than has hitherto been appreciated. A chemical perspective helps solve challenges to understanding subsurface fractures, including how to better use limited subsurface samples, how to interpret ambiguous outcrop analogs, and how to overcome difficulties determining which models are correct from observations.

The paper describes how many tools of chemical analysis, experiment, modeling and theory can be brought to bear on understanding how fracture patterns develop at geological time scales. A major conclusion is that chemical and mechanical investigations together have great potential to solve challenging practical problems in subsurface science.

The theme of chemical-mechanical interaction has been central to the Structural Diagenesis Initiative since the outset.

Four current (Fall 2019) Ph.D. projects are investigating aspects of the role of chemistry in fracture pattern development.

The AGU editors blog features a short article that underscores some of the highlights of the Reviews of Geophysics paper.
