Geological mapping of the area around Baltis Vallis, the longest (6,800 km) canali-type channel on Venus, has led to the determination of stratigraphic relations which appear to be consistent over this entire region comprising -20 x 106 km 2 or -5% of the total surface of Venus. The most abundant unit in the study area, plains with wrinkle ridges (Pwr), consists of two subunits separated by the...

[1] The Nilosyrtis Mensae region is important among dichotomy boundary fretted terrain outcrops, as it provides evidence of overprinting of ancient landscapes by a suite of glacial features, providing a composite view of the variety of midlatitude glacial modification processes that can occur during recent Martian ice ages. On the basis of a series of criteria developed for the identification o...

The fossil record of dinosaurs from the Early Cretaceous of Eastern North America is scant, especially since a few stratigraphic units from the east are fossiliferous. Among these stratigraphic units, the Arundel Clay of the eastern seaboard has produced the best-characterized dinosaur faunas known from the Early Cretaceous of Eastern North America. The diverse dinosaur fauna of the Arundel Cla...

Paleotemperature indicators and apatite fission track analysis of Australian continental margin cover sequeRces accreted to the active Banda arc-continent collision indicate little to no heating during rapid late Neogene uplift and exhumation. Thermal maturation patterns of vitrinite reflectance, conodont alteration and' illite crystallinity show that peak paleotemperatures (PPT) increase with ...

We use multichannel seismic reflection profiles to determine the seismic stratigraphy of the flexural moat that flanks the Canary Islands. The moat stratigraphy has been divided into 5 units on the basis of internal character and correlation of distinctive reflections. The deepest units, I and II, which well-ties indicate are Eocene and older, thicken towards the east suggesting they are the co...

Segev, A., Sass, E., Ron, H., Lang, B., Kolodny, Y., McWilliams, M. 2002. Stratigraphic, geochronologic, and paleomagnetic constraints on Late Cretaceous volcanism in northern Israel. Isr. J. Earth Sci. 51: 297–309. Late Cretaceous volcanism in northern Israel is represented by basaltic pyroclastics and lavas at two adjacent localities at Mount Carmel and the Umm el Fahm area. Four Cenomanian a...

Introduction: Improving the temporal constraints of Martian geologic processes is essential for understanding the formational history of the planet and providing adequate context for exploration. Martian surfaces are generally delineated into discrete packages based on morphological, compositional, and/or temporal characteristics, the latter of which are derived through (1) apparent cross-cutti...

The studied area includes Sulaimani, Erbil and Dohuk Governorates where Cretaceous rocks are well exposed in the High Folded Zone of North and Northeastern Iraq. This area is part of the northwestern boundary of Arabian platform near to Iranian border. In these governorates, the study tries to clarify the relations between deep and shallow stratigraphic units (formation or facies) during Cretac...

In the past 10 years an abundance of new models aimed at finding a better or even the ultimate solution for the structure and evolution of the Mediterranean Tethys have been published. These models are based on new geophysical (mainly paleomagnetic) results, refined stratigraphic and facies data, and sometimes even on detailed geochemical analyses. They were constructed with the help of paleaog...
