The goals of the project are to collect new data from basin analysis studies; geochronology and structural analysis of stratigraphic sections, key faults and shear zones; and to collect paleomagnetic data from within the suture zone to test assumptions about paleogeography and measure the time-space distribution of rotations within the suture zone. These data will provide a new integrated geologic framework to test end-member hypotheses (oroclinal vs. scissor-like closure) and provide new constraints on the 4D evolution of this suture zone with implications for linking surface geology with mantle structure beneath Asia, regional lithospheric structure, and preconditioning for intraplate deformation.

This project aims to understand how rifting, subduction, and terrane accretion have shaped lithospheric structure beneath New England through integrated geophysics and geology. A major focus of this project is the NEST (New England Seismic Transects) experiment, a deployment of ~25 broadband seismometers that is configured to resolve crustal targets on length scales that are appropriate for direct linkage with geological structures, including frontal thrusts of basement massifs and the Taconic Mountains in western New England and New York, and the Connecticut Valley border fault system in central New England.
