Crustal growth in the Coast Mountains, along the leading edge of the Canadian Cordillera, was the result of processes associated with horizontal flow of material during transpression and subsequent transtension, and the vertical accretion of mantle derived melts. From 85 to 58 Ma, as exotic terranes were translated northward during transpression, the crust was thickened to about 55 km, and melt...

We present a new model for the tectonic evolution of the Tasman Sea based on dense satellite altimetry data and a new shipboard data set. We utilized a combined set of revised magnetic anomaly and fracture zone interpretations to calculate relative motions and their uncertainties between the Australian and the Lord Howe Rise plates from 73.6 Ma to 52 Ma when spreading ceased. From chron 31 (67....

3-D microstructural analysis of 30 porphyroblastic samples from the Variscan orogen in NW-Iberia has revealed four sets of inclusion trails with distinctive geographic trends and relative timing. The chronological and orientational consistency of these microstructures provides a reference frame for the correlation of macroscopic structural successions. The two younger inclusion trail sets corre...

Detailed structural geological and related studies were carried out in a number of critical areas in the Proterozoic basement of eastern Egypt to resolve the structural pattern at a regional scale and to assess the general characteristics of tectonic evolution, orogeny and terrane boundaries. Following a brief account of the tectonostratigraphy and timing of the orogenic evolution, the major st...

[1] Nearly complete coverage of shipboard multibeam bathymetry data at the right‐stepping Menard and Pitman Fracture Zones allowed us to map abyssal hill deviations along their traces. In this study we distinguish between (1) J‐shaped curvatures at their origin, where modeling is addressing primary volcanism and faulting following a curved zone, and (2) straight abyssal hills getting bent in an...

Large-scale strike-slip faults are associated with significant strain partitioning in releasing/restraining bends and often display map-view curvatures ending horse-tail geometries. Such commonly indentation tectonics, where shortening front of indenters is transferred laterally to transpression, the formation transtensional/extensional basins. We investigate how these structurally distinct dom...
