How are batholith formed

Web12 de out. de 2024 · The oldest, foliated granite, yielded a zircon U–Pb age of 417.4 ± 1.7 Ma. Following deformation, equigranular granite intruded at 409.8 ± 1.9 Ma and was cut by megacrystic granite at 404.9 ± 2.6 Ma. Hence, batholith formation lasted up to 16.8 myr, challenging the widely accepted 405 Ma age for the entire batholith.
