= Siletzia
{c}
An accreted basaltic terrane forming important parts of the forearc basement in the Pacific Northwest. Spatial variations in its thickness, stiffness and permeability can affect the interpretation of <gravity anomalies> and the fluid/stress environment above the <megathrust>. A proposed relation to central Cascadia creep uses gravity, geodetic and paleoseismic observations, rather than lithology alone.<Central Cascadia subduction zone creep by Gina M.
