Structure and stratigraphy of lower Paleozoic rocks, Doonerak Window, central Brooks Range, Alaska
Deep structural levels of the Brooks Range thrust belt, and a unique sequence of lower Paleozoic rocks (informally named the Apoon assemblage) are exposed in a structural high near Mount Doonerak. Previous workers interpreted ...
Estimating subsurface structure through gravity and gravity gradiometry inversion
We use gravity to estimate rifted margin deep structure with an inversion method that links parameters in the shallow parts of the model to those in the deep parts through an isostatic, uniform extension model. The method ...
Seismic-stratigraphic analysis of shelf-margin delta/slope fan and basin floor fan on high-latitude and middle-latitude margins (Ross Sea, Weddell Sea and Alabama/West Florida shelf): Paleoclimatic and eustatic implications
This dissertation consists of three chapters describing seismic stratigraphic studies in three very different continental margin settings. The first chapter discusses the northwestern Ross Sea, the second discusses the ...
Layer-stripping reverse-time migration
Reverse-time migration has proven to be successful for structures with steep dips and strong velocity contrasts. Applying this algorithm to a large scale seismic model requires significant computational expense, particularly ...
Tectonic evolution of the south-central Caribbean based on geochemical data
Northern Venezuela consists of seven east-west trending tectonostratigraphic belts which are from north to south: Dutch and Venezuelan islands (DVI), Venezuelan platform, Cordillera de la Costa-Margarita terrane (CCMT), ...
FACIES OF LATE PLEISTOCENE GLACIAL MARINE SEDIMENTS ON WHIDBEY ISLAND, WASHINGTON
Detailed mapping of over 10 kms of cliff exposure on Whidbey Island, Washington has resulted in the recognition of six major lithofacies within "Everson" age glacial-marine deposits (late-Pleistocene). These lithofacies ...
