Thrust Belt Fracture Systems

Randy Marrett and Steve Laubach recently completed initial field work on thrust belt fracture systems in mixed siliciclastic/carbonate rock systems.

Results of the study are posted on the Members side under Case Studies.

We plan to conduct a FRAC field trip and Research Meeting in this area in the near future, as it contains several features of potential great interest for exploration, including an example of superporosity due to fracturing.12/30/04

 
 
Support for Research on Evolution of Fracture Systems
The Jackson School of Geosciences recently announced that the Geology Foundation will support our research on fundamental aspects of fracture pattern development. The title of the successful initiative is Fracture Opening Processes: Chemical/Mechanical Evolution of Fracture Systems. Complete information is posted on the members site. 11/15/04

Field Work '04

Planning is underway for the FRAC field trip in July and for student summer field work.

More information is posted on the Members side. 2/20/04

 

New Fracture Picking Method & Software  GoMezure

A new procedure for fracture picking and new software for extracting structural information from scanned CL ../../images for scaling analysis has been developed by Leonel Gomez.

We are currently testing the software on fracture data sets from Wyoming, Colorado, Venezuela, northeast Mexico, and other areas.

A description of the new methodology and the software will be posted on the Member's Site under Transfer Modules. Instruction in the use of the new software is planned for the workshop associated with the July Research Meeting. At that meeting we will also review progress in automated image mosaic acquisition.

The new methodology and software replaces the procedure based on the OrlandoMagic software. An advantage of the shift is that the fracture mapping and extraction procedures use current, cheap and widely available software as a starting point. The new methodology reduces the time it takes to quantify the properties of interpreted fractures and also gives the user tremendous flexibility to quantify those properties.

Steve Laubach has been named a Jackson Research Fellow for 2004-2005.

Robert K. Goldhammer Chair in Carbonate Geology
 

A new chair has been formally approved in the Geology Foundation. It was established by the Goldhammer Family Foundation in memory and honor of Professor Bob Goldhammer. It will be known as the Robert K. Goldhammer Chair in Carbonate Geology.

The Chair is restricted to faculty doing research in carbonate stratigraphy and sedimentology, but excluding carbonate geochemistry as a principal field of endeavor.
