Crustal structure and tectonic evolution: Central California
Vertical incidence and wide angle seismic data suggest the central California transform margin is underlain at depth by a horizontal detachment surface above which strike-slip and compression occur. The boundary between ...
Turbidite deposition on the Bellingshausen Abyssal Plain: sedimentologic implications
A number of piston cores from the Bellingshausen abyssal plain contain gravel and sand units which are interpreted as turbidites deposited in submarine channels. Middle and outer fan deposits are lacking, although core ...
Marine geology of the northwestern Weddell Sea and adjacent coastal fjords and bays: implications for glacial history
Sedimentologic, compositional, and cleat shape analyses reveal that piston cores obtained on the northwest Weddell See continental shelf penetrated residual glacial marine sediments adjacent to Seymour Island, compound ...
Seismic stratigraphy of the Northwest Gulf of Mexico
Pleistocene sedimentation at the outer continental shelf of the northwest Gulf of Mexico was related to eustatic fluctuations of sea level during the Wisconsin period. Four seismic sequences interpreted from high resolution ...
The use of vertical grain size progressions in establishing the depositional environment of ancient sand bodies
This study demonstrates the validity of using vertical grain size progressions as an environmental indicator for ancient clastic sequences. Previous methods of grain size analysis are shown to be generally unreliable for ...
A structural study of the Hukou and Hsinchu areas Northwestern Taiwan
Northwestern Taiwan, which includes the Kuanyin, Hukou and Hsinchu areas, was initially a part of the continental shelf of the mainland China coast. The Neogene sediments were deposited m gently east-dipping basement in a ...
