gigayear
A billion (10) years

These syntheses gave a fresh geological, as opposed to solely geophysical, view of the up to multi-megayear and near gigayear mechanism responsble for the palimpsests of a general process of change in the upper crust: a process that we may observe, often apparently frozen because it is so slow, at different steps in the process, in different places within the upper crust.
