Although Grande Ronde Basalt exposures are limited in the study area (Hutter, 1997, Schuster et al., 1997), these rocks undoubtedly comprise a large part of the CRBG section at depth. Grande Ronde Basalt is overlain by Wanapum (15.6 to 14.5 Ma) and Saddle Mountains Basalt (14.5 to 6.0 Ma), both exposed in the study area.
Oceanic lithosphere and basins are the result of plate tectonics, the process that shapes the Earth's surface. This webpage explains how oceanic lithosphere forms at divergent boundaries, how it interacts with continental lithosphere at convergent boundaries, and how it influences the shape and depth of ocean basins.

The cross-sectional area is a geometric property of structural elements such as beams, columns, slabs, etc. and it is used to calculate the axial stresses in Cross-sections. In general it can be said that the greater the dimensions of a cross-section under a given load, the greater the Cross-sectional area and the smaller the axial stress.
