Dinoflagellate cysts from the Upper Triassic (Rhaetian) strata of the Tabas Block, East - Central Iran
Rhaetian strata from the Nayband Formation of the Tabas block, East- Central Iran, were studied palynologically. The materialexamined contained moderately diverse and well-preserved dinoflagellate cyst assemblages which lead to the identification ofRhaetogonyaulax rhaetica Zone. The assigned age of this dinozone (Rhaetian) is justified by plant fossils such as Equisetitesarenaceus, Scytophyllum...
متن کاملFeasibility of time-lapse gravity monitoring of producing gas fields in the Northern Carnarvon Basin, Australia
Figure 1. Model of P-wave velocity (above) and density (below) verses gas saturation for a sandstone reservoir with a porosity of 25%. The velocity was modelled using Gassmann’s equation (1951) with the Reuss average moduli of the fluids. For a gas saturated reservoir, a decrease in gas saturation causes a negligible change in the P-wave velocity for saturations above 20% and more significant c...

متن کاملCritical comment on: A.J. Mory et al. `Woodleigh, Carnarvon Basin, Western Australia: a new 120 km diameter impact structure'
Mory et al. [1] claim to report `a newly discovered basement-cored, multi-ring impact structure' and hint `at a possible Permian^Triassic boundary age for the impact'. They purport that this structure could be as large as 120 km in diameter. This comment emphasizes that these authors indeed identi¢ed a potentially interesting structure, but that the evidence presented is inconclusive and not we...
متن کاملAngiosperm-like pollen and Afropollis from the Middle Triassic (Anisian) of the Germanic Basin (Northern Switzerland)
Here we report on angiosperm-like pollen and Afropollis from the Anisian (Middle Triassic, 247.2-242.0 Ma) of a mid-latitudinal site in Northern Switzerland. Small monosulcate pollen grains with typical reticulate (semitectate) sculpture, columellate structure of the sexine and thin nexine show close similarities to early angiosperm pollen known from the Early Cretaceous. However, they differ i...
