Rapid early Miocene exhumation of the Ladakh batholith, western Himalaya

Geochronologic Constraints on the Tectonic Evolution and Exhumation of Nanga Parbat, Western Himalaya Syntaxis, Revisited

We examine the timing of deformation and exhumation of the Nanga Parbat-Haramosh massif in the western syntaxis of the Himalaya. This study presents geochronologic and thermochronologic data obtained from basement, shear zone, and intrusive units within the massif to reveal the Cenozoic tectonic evolution of the massif and to document the extent of the Plio-Pleistocene tectonic activity. These ...

Testing Models of Ultra-Fast India-Asia Convergence: New Paleomagnetic Results from Ladakh, Western Himalaya

Rapid India-Asia convergence has led to a major continental collision and formation of the Himalayas, the highest mountain range on Earth. Knowledge of the paleolatitude of the Kohistan-Ladakh Arc (KLA), an intermediate tectonic unit currently situated between the converging Indian and Eurasian continents in Western Himalaya, would constrain the tectonic history and dynamics of Himalayan orogen...

Hybridization of granitic magmas in the source: The origin of the Karakoram Batholith, Ladakh, NW India

Growth and Deformation of the Ladakh Batholith, Northwest Himalayas: Implications for Timing of Continental Collision and Origin of Calc-Alkaline Batholiths.

The calc-alkaline Ladakh batholith (NW Himalayas) was dated to constrain the timing of continental collision and subsequent deformation. Batholith growth ended when collision disrupted subduction of the Tethyan oceanic lithosphere, and thus the youngest magmatic pulse indirectly dates the collision. Both U-Pb ages on zircons from three samples of the Ladakh batholith and K-Ar from one subvolcan...
