Continental rifts evolve along two possible paths. In one, a rift successfully evolves into
seafloor spreading, leaving the rift structures buried beneath thick sedimentary and volcanic …

Uncertainty exists in the configuration and extent of the Midcontinent Rift System (MRS)
because of deficiencies in geophysical data and limited information from outcrops and …

The amalgamation of Laurentia's Archean provinces ca. 1830 Ma was followed by~ 700 my
of accretionary orogenesis along its active southeastern margin, marked by subduction of …

Seismic wave speed is controlled by a number of factors, including temperature and
chemical composition, as well as the presence of volatiles and partial melt. Tomography …

Broadband seismograms from the EarthScope Transportable Array and Superior Province
Rifting EarthScope Experiment (SPREE) deployments are used to map the crust and …

The Laramide foreland belt comprises a broad region of thick-skinned, contractional
deformation characterized by an anastomosing network of basement-cored arches and …

Continental flood basalt lavas often contain deeply-sourced, thermo-chemically anomalous
material that can provide a potential probe of inaccessible reservoirs. However, continental …

We present a methodology for 1-D imaging of upper-mantle structure using a Bayesian
approach that incorporates a novel combination of seismic data types and an adaptive …

Cratons are generally considered to comprise lithosphere that has remained tectonically
quiescent for billions of years. Direct evidence for stability is mainly founded in the …

Mechanisms responsible for the long-term subsidence of intracontinental basins such as the
Williston Basin in North America remain enigmatic, partly due to the thick sedimentary layer …
