U-Pb zircon ages of a tonalite and a granodiorite dykefrom the southeastern part of the Bindal Batholith,central Norwegian Caledonides
An elongate tonalite pluton and a c.10 m-thick granodiorite body in the southeastern part of the Bindal Batholithand Helgeland Nappe Complex, Nord-Trøndelag, have yielded U-Pb zircon ages of 429 \u00B12 and 430 \u00B12 Ma, respectively. These dates are interpreted to represent the crystallisation ag...
