How landscapes become strata: advances in linking surface processes to the stratigraphic record
Session ID#: 251539
Session Description:
Sedimentary strata are the product of past surface processes. Deciphering the stratigraphic record is crucial to: (1) reconstruct ancient landscapes and environments; (2) understand sedimentary processes across planetary surfaces; and (3) quantify landscape responses to tectonic and climatic change. This session welcomes contributions that focus on reconstructing—or advance our ability to reconstruct—paleoenvironment histories and surface processes on Earth and other bodies from sedimentary rocks. Topics of interest include, but are not limited to: the influence of climatic, tectonic and/or anthropogenic forcings on landscapes evolution and stratigraphic development; depositional signatures of discrete events; mechanisms governing the preservation or shredding of environmental signals in the stratigraphic record. We encourage contributions that tackle these challenges using fieldwork, remote sensing, physical experiments, and/or numerical models.
