Explorer Geophysical Corner

This month, we further evolve this framework to build a palinspastically quantitative reassembly of continents and continental blocks that were separated during the Mesozoic rifting and subsequent drift in the Gulf of Mexico region -- key features.

One hundred years of petroleum exploration and development in the Los Angeles region have produced a rich legacy of geological and geophysical data -- a legacy that the oil industry has spent billions of dollars to obtain.

An unfortunate fact of geology is that most datasets, including seismic, rarely allow for a unique interpretation of a geological problem.

Earthquakes in the center of the country. It's a great story, but whether true or not, a big question remains: Could it happen again today?

Amos M. Nur swayed from a rope ladder on a rugged cliff by the Sea of Galilee. Nur, a 1998-99 AAPG Distinguished Lecturer, came to this remote location to pursue a 2,000-year-old mystery.

DL Abstract

While there are many habitats that are associated with the deposition of organic-rich marine and lacustrine source rocks, one important pathway is linked to the onset of increased basin subsidence associated with major tectonic events. A key aspect is that this subsidence is spatially variable, with the uplift of basin flanks contemporaneous with the foundering of the basin center, resulting in a steeper basin profile.

DL Abstract

For well over a century there have been conflicting indications of the strength of the crust and of faults and what controls them.  Much of our ignorance comes quite naturally from the general inaccessibility of the crust to measurement--in contrast with our understanding of the atmosphere, which is much more accessible to observation as well as more rapidly changing.  Crustal strength is best understood in deforming sedimentary basins where the petroleum industry has made great contributions, particularly in deforming petroleum basins because of the practical need to predict. In this talk we take a broad look at key issues in crustal strength and deformation and what we can learn from boreholes, earthquakes, active fault systems, and toy models.

VG Abstract

In comparison with the known boundary conditions that promote salt deformation and flow in sedimentary basins, the processes involved with the mobilization of clay-rich detrital sediments are far less well established. This talk will use seismic examples in different tectonic settings to document the variety of shale geometries that can be formed under brittle and ductile deformations.
