Document Summary

Analytic continuations: transforms the field to how it would look like at different elevations. Up = far away from sources; down= closer to sources. Data transformations: examples (upward continued or low-passed tmi) Residual = orig regional ==> resid = orig upward continued tmi. The application of analysis of geological structures and applying these approaches to regional (and local) geophysical datasets : 3d geometry, overprinting (sequence of events that cause the geometry), *kinematics (movements of the rocks). If you"re a structural geologist/geologist: where do i start, understanding the data how it is processed, converting a dataset that tells me about one physical property of the earth into a geological observation or process. Look like a map think about the end users. Kinematics of faults (we"ll talk about that later). Can the map inform tectonic setting and processes or regional evolution. Should be predictive regional strain fields, dilation sites, alteration zones etc. (assist targeting). Temporally and spatially correlating geological events (over distances).
