Session No. 90: P1. Bottoms Up: Perspectives from “bottom-up” and “top-down” approaches to tectonic reconstructions


Session Chairs:
Chance Ronemus | Department of Geosciences, Jonny Wu, Erin Donaghy, Guido Gianni | Institute of Geophysics, Craig Martin | Department of Earth and Planetary Sciences, Jackson School of Geosciences

Description:

This symposium pairs invited speakers who use “top-down” (i.e., study of rocks at the surface) and “bottom-up” (i.e., geophysics and modeling techniques) approaches to address tectonic histories and processes. We emphasize topics where these perspectives yield both complementary and conflicting information, with the goal of fostering interdisciplinary dialogue toward more integrative tectonic frameworks.
