Tectonic subsidence analysis of the Williston Basin
… of North American intracratonic basins whose subsidence is poorly understood. The Basin is circular in shape and contains nearly 5 km of preserved sedimentary rocks at its center; ranging from Cambrian to Tertiary in age. The Basin's subsidence is investigated quantitatively using the …

Cyclostratigraphy of Late Cambrian cyclic carbonates: An interbasinal field and modelling study, U.S.A.
… produced by eustacy beyond that provided by subsidence. Residual eustatic curves derived from subsidence analysis are useful for correlating the longer-term Late Cambrian sea level events and changes in the rate of sea level rise and fall can be used to define shorter-term events. Combining …

Continental Deformation: Collisional Orogenesis to Passive Margin Processes
… accompanying model to the entire Himalaya; and a subsidence analysis of the northern abyssal Gulf of Mexico (GoM), which I use to evaluate numerical models of North American dynamic topography. GPS shows southern Tibet creeps south at the same rate river terraces are deformed at the range front. …

Hazard Identification and Coastal Stratigraphy in Crescent Harbor, Northeast Whidbey Island, Washington
… overlain by intertidal mud, indicating rapid subsidence. Analysis of the modern-day position of depositional facies indicates subsidence from a high marsh to a tidal-flat environment representing an estimated 1.7 m elevation change. The timing of subsidence fits within the dates of a rupture …

Tectonic history of Billings and southern McKenzie Counties, southwestern North Dakota
… structures. Isopach map patterns, along with subsidence analysis were used to identify episodes of tectonic activity within the area. </p><p> Although the subsidence of the Williston Basin was the principal regional tectonic activity, the structural features in Billings and McKenzie Counties …

Controlling factors of two Middle Triassic carbonate platforms: Latemar and Rosengarten (Dolomites, Northern Italy)
Integrated facies and subsidence analysis enable the identification and quantification of controlling factors on carbonate platform evolution. Palaeo biologic evolution as intrinsic factors, subsidence and accommodation change as extrinsic factors are the most important controlling factors on …

Modelling of Subsidence in Geothermal Fields
Subsidence is an environmental issue at New Zealand geothermal fields, particularly Wairakei. It has resulted in submissions to geothermal resource consent hearings, subsequent operational consent conditions and long-term monitoring programs. Wairakei geothermal field has a complex subsidence …

MAGANOM : a computer program for the modeling and interpretation of marine magnetic anomalies with an example from the Cayman Trough, northwest Caribbean Sea
… Evaluation of opening rates based upon crustal subsidence analysis and magnetic anomaly interpretation shows the Trough to have opened at less than half previously proposed rates. Depths to basement show that the crust has subsided from the present axis in two stages, a younger stage …

Epeirogeny of South America and Evolution of Parnaíba Basin, Northeast Brazil
… direct consequence of intensified Andean uplift. Analysis of the Parna\'iba cratonic basin of northeast Brazil is carried out to evaluate long-term evolution of vertical motions and to understand the mechanisms driving this basin's subsidence. Joint interpretation of a deep seismic reflection …

Triassic to Neogene Evolution of the Andean Retroarc: Neuquén Basin, Argentina
… timing of the transition from post-rift thermal subsidence to foreland basin deposition in the northern Neuquén Basin and then assess volcanic activity and composition during various tectonic regimes. The Aconcagua and Malargüe areas (32°S and 35°S) are located in the northern segment of the …

Nuevo modelo Madrid para la estimación de asientos producidos en túneles con tuneladoras epb de gran diámetro
… frame of Madrid (city and surroundings) and analysis of geotechnical features, mainly the ones related to on-site deformability of soils. - Description of the different extensions developed in Metro de Madrid in order to understand the importance of setting up a future model (in spite of …
