Fisson track dating
The greatest basaltic thicknesses are recorded in Heimefrontfjella and H. 2) Late Paleogene cooling is attributed to the transition from green house to icehouse conditions and ice-sheet initiation at the Eocene-Oligocene boundary.
Post-Jurassic denudation of at least 2 km in some places is suggested....
WUSEM shows reliable results when used in photomicrographs presenting almost isotropic objects.
Here, we investigate the post-emplacement kinematics and exhumation history of the Almora klippe.New ZFT cooling ages along ~50-kmlong orogeny perpendicular transect across the Almoraklippe range between 13.4 ± 0.6 and 21.4 ± 0.9 Ma.Published AFT ages and 40Ar–39Ar ages from the Almora–Dadeldhura klippe range 3.7 ± 0.8–13.2 ± 2.7 and 18.20–25.69 Ma, respectively.South of the Mazatag Ridge a significant eolian deposit accumulated ~500 yr ago, but this has been deflated in more recent times.Comparison of the modern river data with those previously measured from Cenozoic foreland sedimentary rocks shows that no sediment similar to that of the modern Yarkand River is seen in the geologic record, which is inferred to be younger than 11 Ma, and probably much less. 17 Ma, somewhat after that of the Pamir and Songpan Garze of northwestern Tibet, dated to before 24 Ma.
