Geophysical constraints on the thickness of the Holyrood Pluton, Avalon Peninsula, Newfoundland
The vertical extent of the Holyrood Pluton and the surrounding Harbpur Main Group of the northeastern Avalon Peninsula of Newfoundland is estimated using two-dimensional gravity and magnetic models. The models are interpreted to indicate that the maximum thickness of the Holyrood Pluton is 1.8 km an...
