The Rock Fracture Knowledgebase is an Internet-based repository or a modern digital book about rock fracturing and the resulting structures. Starting from basic single fracture types: joints, pressure solution seams, deformation bands, and faults, the Knowledgebase explores further the concepts of fracture zones, sets, multiple sets, domains, and assemblages. It goes on to demonstrate how the formation, distribution, and petrophysical and geostatistical properties of fracture classes are related to their formation mechanisms and mechanics.

A preview of the Rock Fracture Knowledgebase is available from here (in a new browser tab). New readers may start with the Readme page, also available on the footer of all pages. The Readme provides a guided tour or preview of the Knowledgebase using 10 pages as examples. It also provides information on how the Knowledgebase is organized and its navigation options.

The full content of the Rock Fracture Knowledgebase is available for 2-year subscription. Individual subscription for $34.95/2yr is available from Multi-user subscription for academic research groups and libraries is $990/2yr and $1,900/2yr for for-profit corporations. If interested in the academic or corporate subscription, please email and/or, or use the Contact Us form.

Note: Most of the links on the Preview pages are disabled. So, if you click on a link and it does not work, the linked page is not part of the preview. Only the Table of Contents and pages mentioned in the Readme are available for preview.

About the authors

Atilla Aydin was born in a small village in eastern Turkey. Partly because of his good luck, he ended up in lands far away from his birth place. He 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 (California, USA). He taught Structural Geology for about 10 years at Purdue University (Indiana) and a graduate course titled Faults, Fractures, and Fluid Flow at Stanford University for about two decades. The latter led to the inception of this Knowledgebase. He is the author or coauthor of more than 140 refereed papers, the references for which can be found here.

Atilla was the co-founder and co-director of the Rock Fracture Project and the founder and director of the Shale Smear Project at Stanford University. Many field trip guidebooks and numerous workshop volumes out of these projects are now available in digital (pdf) format from the Rock Fracture Project and Shale Smear Project data repositories of the Stanford University Library free of charge.

He is presently Emeritus Professor of Research at the Department of Geological Sciences 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.
