Background: Voyager images of Europa showed evidence of both strike-slip displacement and dilation along cracks [1]. Galileo images confirmed that dila-tion has been common and widely distributed. Large crustal plates have separated, with the space between them filled by new surface material creating dilational bands. Similarly, new surface has also been created along strike-slip faults, where ...

The Gulf of Aden displays an ideal setting to study oblique rift processes since numerous structural data are available onshore and offshore, down to the ocean-continent transition (OCT). We investigate key observations by means of 3D numerical thermo-mechanical experiments on lithospheric scale. The Gulf formed with a rift-normal of -15° azimuth and under the influence of a supposedly 25° tren...

Conjugate, or bimodal, fault patterns dominate the geological literature on shear failure. Based on Anderson's (1905) application of the Mohr-Coulomb failure criterion, these patterns have been interpreted from all tectonic regimes, including normal, strike-slip and thrust (reverse) faulting. However, a fundamental limitation of the Mohr-Coulomb failure criterion e and others that assume faults...

We present a data set of calcite twinning strain results (n = 209 samples; 9919 measured twins) from the internal Alpine nappes northwestward across Alps and foreland to older extensional margin along Atlantic coast in Ireland. Along Northern Ireland, Cretaceous chalks Tertiary basalts are cross-cut by veins offset calcite-filled normal strike-slip faults. Both Irish sample suites 16 with four ...
