The astronomical theory of paleoclimate change accounts for insolation variations arising from changes in the Earth’s orbit, axial tilt and precession, and is recorded in cyclostratigraphy. The advent of high-resolution, globally distributed paleoclimate records has greatly facilitated the investigation of the astronomically forced paleoclimate system from cyclostratigraphy. Today, state-of-the-art Solar System solutions enable improved calibration of cyclostratigraphy to Earth’s orbital cycles, coupled with new geophysical models of Earth’s tilt and precession back in time. These innovations have facilitated the reconstruction of the geological time scale at unprecedented high resolution and accuracy, and to insights into Earth’s long-term orbital-rotational dynamics and the chaotic nature of the ancient Solar System. This session invites contributions that apply cyclostratigraphy to the study of paleoclimate responses to astronomical forcing across geologic time, the development of astrochronology, Earth-Moon dynamical evolution, and the geologic steering of deep time Solar System solutions.
