Upper mantle reflectivity beneath an intracratonic basin: insights into the behavior of the mantle beneath Illinois basin.
Reflectivity images of the lower crust and uppermost mantle beneath the Illinois basin have been derived from reprocessing of several hundred kilometers of industry seismic reflection data using extended vibroseis recorrelation. The recorrelation was based on extending an originally 4-s correlated …

Sound velocity study of natural orthopyroxenes with varying iron content
… to identify the underlying causes of seismic heterogeneity. Such laboratory measurements are essential to determine the structure, composition and temperature variability of the upper mantle. This study presents a systematic characterization of orthopyroxene elastic moduli as a function of …
