The 15 kilometer wide Sovanco Fracture Zone is a dextral-slip transform fault linking the Juan de Fuca and Explorer Ridges in the N.E. Pacific. SEABEAM bathymetry shows that the Sovanco comprises several rhomb-shaped elevated blocks of oceanic crust bounded by northeast- and northwest-trending lineaments. We hypothesize that the northeast-trending lineaments are sinistral strike-slip faults that are reactivated ridge-parallel normal faults. Both the sinistral block-bounding faults and the blocks themselves have rotated clockwise about 30 degrees in response to dextral shear within the Sovanco zone.
