The following symposium may be of interest to readers of the Geotectonics list: ______________________________________________________ 7th International Conference on Fluvial Sedimentology Nebraska, USA, August 6-10th 2001. 2nd circular: Papers are invited for the following special symposium: "Alluvial and tectonic system interactions" Convened by: Jon Holbrook (Missouri State, USA) [log in to unmask] Anne Mather (Plymouth UK) [log in to unmask] Martin Stokes (Plymouth, UK) [log in to unmask] Registration and abstract submission can be done online at: http://www.unl.edu/geology/ICFS.html If you intend to submit an abstract for the session then please e.mail it to the session convenors (above), as well as the abstract co-ordinator (Joe Mason: [log in to unmask]). We hope to see you all in Nebraska Jon, Anne & Martin ______________________________________________________ "Alluvial and tectonic system interactions" Alluvial systems are sensitive to even the subtlest tectonic perturbations, and may adjust through incision, aggradation, shifting, and/or morphological changes. Alluvial systems are also the main instrument in the destruction and modification of tectonic landforms. Unravelling these alluvial-tectonic feedback relationships is pivotal to comprehending both alluvial and tectonic systems. This session will address recognition of sedimentologic and geomorphologic evidence for tectonic control, at a range of geographical (river reach to sedimentary basin) and temporal (modern to ancient) scales. Papers are particularly encouraged which quantify the causes and rates for natural feedback between tectonic and alluvial systems, and/or illustrate how these data can/should be used to help constrain regional and/or local tectonic parameters (e.g. distribution, orientations, structural styles, deformation rates and periodicities, etc.).
