Abstract Late Cenozoic was a period of large-scale extension in the Aegean. The is mainly recorded metamorphic core complexes with little data from sedimentary sequences. exception Thrace Basin northern Aegean, which has continuous record Middle Eocene to Oligocene marine sedimentation. In Basin, Oligocene–Early Miocene characterized by north-northwest (N25°W) shortening leading termination sed...

The Cenozoic succession of the East Pisco Basin preserves sedimentary record several episodes deformation forearc crust along Peruvian margin. 1:50,000 scale geological map presented here encompasses an area about 1,000 km2 lying astride Ica River, and contributes to our understanding timing mode basin filling deformation. Our novel two-fold megasequence framework provides a sound basis for est...

New low-temperature thermochronology data from clastic sedimentary rocks in the northern Richardson Mountains, Canada, indicate significant exhumational cooling during late Eocene–early Oligocene time. Apatite (U-Th-Sm)/He (AHe) were collected 19 Proterozoic–Paleocene across a 115 km transect. Eighty-eight single-grain AHe dates range 16–300 Ma and are generally younger than stratigraphic ages,...

This research focusses on the biostratigraphy and paleoecological implications of the carbonatesof the Asmari Formation. The Asmari Formation is located in the Siah Kuhanticline of Izeh, Zagros Basin, SW Iran. It is of Late Oligocene (Chattian) - Early Miocene (Burdigalian) age. In this stratigraphic section, the Asmari Formation overlies the Pabdeh Formation and underlies the Gachsaran Formati...

Understanding which factors have driven the evolutionary success of a group is a fundamental question in biology. Angiosperms are the most successful group in plants and have radiated and adapted to various habitats. Among angiosperms, legumes are a good example for such successful radiation and adaptation. We here investigated how the interplay of past climate changes, geographical expansion a...
