16th Annual Fracture Research & Application Consortium Meeting
Scheduled for Camp Balcones Springs in the the Texas Hill Country September 15th through 17th, the meeting will feature a field workshop on new approaches to spatial organization and an introduction to new software for quantifying fracture clustering. Many SDI students will present their work to a select industry audience of structure and exploration & development experts. See the Events page for more information.
2014 Field Expedition to the Northern Tetons, Wyoming
A successful field expedition to NW Wyoming was concluded in late August. Lauren Copley’s field party examined fractures in Cambrian rocks as part of a National Park Service sanctioned research project. The study is aimed at understanding deformation patterns associated with basement-involved reverse faults. Lauren Copley will present preliminary results of the study at this year’s Geological Society of America meeting in Vancouver. The image, by Eva Laubach, field assistant and expedition photographer, shows the field party preparing to set out, at 5 am under starlight and moonlight, on a 16 mile hike covering more than 5000 ft of elevation gain to view exposures deep in the range. More information and photographs will be provided on the SDI field expeditions page.
2014 International Year of Crystallography
The International Year of Crystallography 2014 (IYCr2014) commemorates the centennial of X-ray diffraction and the 400th anniversary of Kepler’s observation in 1611 of the symmetrical form of ice crystals, which began the wider study of the role of symmetry in matter.
The Structural Diagenesis Initiative is doing it’s part by helping to rewrite the book on how quartz — the most important mineral in the Earth’s crust — grows in fractures:
- Lander R.H., and Laubach, S.E., in press, Insights into rates of fracture growth and sealing from a model for quartz cementation in fractured sandstones. Geological Society of America Bulletin. | A general model for quartz growth in fractures.
- Fall, A., Eichhubl, P., Bodnar, R. J., Laubach, S. E., Davis, J. S., 2014, Natural hydraulic fracturing of tight-gas sandstone reservoirs, Piceance Basin, Colorado.

Recognition for Slow Fracture Opening Account | Citations
According to the Geological Society of America, as of June 2014, the SDI paper describing A 48 m.y. history of fracture opening, temperature, and fluid pressure: Cretaceous Travis Peak Formation, East Texas basin, is the third mostly highly cited recent article in the Geological Society of America Bulletin. The paper by S.P. Becker, P. Eichhubl, S.E. Laubach, R.M. Reed, R.H. Lander, and R.J. Bodnar was published July 2010, in v. 122, no. 7-8, p. 1081-1093. doi:10.1130/B26404.1. The GSA list is here.

The review paper provides a historical perspective on microfracture research and an appreciation of future research directions. Among the topics discussed are experimentally produced microfractures, paleostress and microfractures, scaling of microfracture aperture and length, microfractures in shale, sealing of microfractures, and an assessment of geomechanical and geochemical interaction in microfracture development.
