Carbonate cementation in Upper Eocene clastic reservoir rocks from the North Alpine Foreland Basin (Austria)

Tectonosedimentary evolution of the basins in Central Alborz, Iran

Evidence of at least ten different tectonic- controlled sedimentary basins can be recognized in the central part of the Alborz Mountains in the Middle part of the Alpine-Himalayan belt. They formed from Neoprotrozoic to recent time as the results of the relative plate motion in southwest of Asia in Tethyan realm. The basins include: (1) Prototethys Late Neo-Proterozoic to Early Ordovician epi-c...

Geochemical study of lower Eocene volcanic ash layers from the Alpine Anthering Formation, Austria

Samples of bentonite layers from altered volcanic ash layers of the Anthering Formation in Salzburg, Austria, which most likely covers the Paleocene/Eocene boundary, were analyzed for their chemical composition. The results of the major and trace element determination confirm the previously suggested appearance from at least two different primary localities. One sample has low abundances in TiO...

Tectonic control on coarse-grained foreland-basin sequences: An example from the Cordilleran foreland basin, Utah

Figure 1. A: Map of Charleston-Nebo salient and northernmost Book Cliffs showing rock units, thrust faults (dashed where buried), key seismic coverage (gray lines), measured stratigraphic sections (1–7; 8 is location of additional Blackhawk sandstone samples), and wells. Rock units: KTs—Cretaceous–Tertiary strata (North Horn and younger formations), Kmv—Cretaceous Mesaverde Group (Blackhawk, Ca...

Chemical Induced Wettability Alteration of Carbonate Reservoir Rocks

Long-term sediment accumulation in the Middle Jurassic–early Eocene Cordilleran retroarc foreland-basin system

The late Middle Jurassic–early Eocene (;120 m.y.) sediment-accumulation history of the Cordilleran foreland basin in northern Utah exhibits a sigmoidal pattern on a rate vs. time plot, with moderate rates of accumulation during late Middle Jurassic, very low net rates during Late Jurassic–earliest Cretaceous, increasingly rapid rates during Earlymiddle Cretaceous, and low rates during Late Cret...
