Transpression and transtension zones

Formation of new continental crust in Western British Columbia during transpression and transtension

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...

Abyssal hill deflections at Pacific‐Antarctic ridge‐transform intersections

[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...

Hybridization and Hybrid Zones

Several primate taxa show evidence of natural hybridization, and recent genomic analyses of modern and archaic humans have revealed the prevalence of hybridization during the evolutionary history of our own lineage. Thus interest in understanding how natural hybridization occurs in our closest relatives, the nonhuman primates, has grown rapidly. However, studies of the process and dynamics of h...
