The geology of the oceanographer fracture zone: A model for fracture zones

Journal of Geophysical Research, 1976
An unreversed refraction experiment located 325 km west of the center of the Oceanographer transform and aligned along the axis of the fracture zone yielded information on the velocity structure of the crust within the fracture zone axis. A layer 2 km thick having a compressional wave velocity of 4.4 km/s overlies a layer with a compressional wave ...

A theory of fracture of materials and its application to geology

Transactions, American Geophysical Union, 1950
A theory of fracture of materials is developed which encompasses shear and tension failure. The probability of fracture occurring across a given surface element in an isotropic medium is assumed to be a general function of the limiting normal and tangential stresses across that element. A modification is later introduced to allow for anisotropy wherein

The axial cleavage fracture 1 Axial cleavage fracturing, a significant process in mining and geology

Engineering Geology, 1965
Abstract The attention is called to the systematic occurrence of fracturing in brittle rock parallel to the major load axis at triaxial differential compressive loading. The axial fracture plane shows the features of the tensile brittle ( cleavage) fracture; this circumstance has led to the nomenclature “axial cleavage fracture”.

Hands-On Exercise in Environmental Structural Geology Using a Fracture Block Model

Journal of Geoscience Education, 2001
A scale analog model of an actual fractured rock reservoir was developed to demonstrate the relative utility of structural methods in predicting groundwater flow directions. Students performed several standard structural analyses directly on the fracture block rather than paper copies of fracture maps as in standard exercises.
