Seismic traveltime inversion of wide-angle data for strongly-varying structure: Central Chilean margin and the subducting Juan Fernandez Ridge
This thesis presents the results of traveltime inversion of seismic wide-angle reflection/refraction data for strongly varying media. The two-dimensional velocity structure along two lines across the central Chilean margin ...
A sequence stratigraphic analysis of the late Jurassic-Turonian in the context of the evolution of the West Siberian basin
During the Triassic, Siberia was a basin approximately 1800 kilometers wide filled by red beds and the widespread Tunguska basalts. Rifting occurred in the northern part of the basin. The western part of the Siberian basin ...
The present location of the Nubia-Somalia-Antarctica triple junction
I estimated 75 previously unavailable sea-floor spreading rates from shipboard and airplane magnetic profiles. To estimate the location of the Nubia-Somalia-Antarctica triple junction along the Southwest Indian Ridge (SWIR) ...
Structural and tectonic interpretation of deep seismic reflection data offshore Spain and Portugal: A tectonic rifting model
A portion of new seismic reflection/refraction data collected over the Iberia margin were processed and interpreted, resulting in the recognition of two previously unknown normal faults in the deep crust. These faults, ...
Near-surface seismic imaging at a porphyry copper mine
In June 1996, a 2-D high-resolution seismic survey was conducted at an open pit porphyry copper mine in southwest New Mexico. The local geology consists of a Miocene conglomerate, overlying Precambrian to Eocene basement ...
