Deconvolving episodic age spectra from zircons of the Ladakh Batholith, northwest Indian Himalaya

White, Lloyd; Ahmad, Talat; Ireland, Trevor; Lister, Gordon; Forster, Margaret

Description

We present U/Pb SHRIMP dates of zircons from 7 key samples of the Ladakh Batholith to reconcile the many, often conflicting ages that have been proposed according to various geochronological techniques. Various crosscutting magmatic phases were dated to determine the age of granitoid emplacement. Our results indicate that granitoid emplacement occurred between 66Ma and 46Ma. The final phase of magmatism is characterized by the emplacement of crosscutting fine-grained granite (leucogranite), and...[Show more]
