Rock Fracture

The Rock Fracture Knowledgebase is an Internet-based repository about rock fracturing and the resulting structures. Assuming a basic knowledge of structural geology and geomechanics, it emphasizes the relationship between structural associations and their formation mechanisms and properties. Starting from basic single structures of joints, pressure solution seams, deformation bands, and faults, the Knowledgebase explores fracture zones, sets, multiple sets, domains, and assemblages with field examples. It goes on to demonstrate how mechanisms and mechanics are related to the formation, distribution, and petrophysical and geostatistical properties of fracture classes. The full content of the Knowledgebase is online by subscription. A preview available from here.

Atilla Aydin received his B.S. degree in Geological Engineering from Istanbul Technical University (Turkey) and M.S. and Ph. D. degrees in Geology from Stanford University (USA). He taught Structural Geology for about 10 years at Purdue University and a graduate course in Faults, Fractures, and Fluid Flow for about two decades at Stanford University, which lead to the inception of this Knowledgebase. At Stanford he was the co-director of the Rock Fracture Project and director of the Shale Smear Project. His research interests include physical processes of rock fracturing, faulting, and fluid flow through fractured rock. He is the author or coauthor of more than 140 refereed papers, many fieldtrip guidebooks, and numerous workshop volumes. A complete list of his journal publications can be found at He is currently an Emeritus Professor at Stanford.

Jian Zhong received her B.S. degree in Geochemistry from the University of Science and Technology of China, M.S. degree in Geoscience and Computer Science from SUNY Stony Brook, and Ph.D. degree in Geology from Stanford University. Her dissertation under the supervision of the senior author was focused on Ontology application and knowledge representation in Structural Geology. She is currently a resident tech mentor in the Silicon Valley.
