Agate bandwidths are analyzed and shown to consist of spatial chirps. It is shown that (a) bands are created by following an equal volume mode and (b) the spatial chirps are approximately spherical and concentrated at different “disturbance” locations in the individual agate sectors. Results indicate that the sequence of formation started with banding under a nonlinear process in a gel matrix and were secondarily deformed by external forces. View Full-Text
