The Silver Tip structure in the northern Absaroka volcanic field in Montana consists of a core of Precambrian metamorphic rocks that was differentially uplifted more than 2,500 m during Eocene time. Dikes and sills of rhyodacitic porphyry surround the Precambrian core, which has a diameter of about 4.5 km. A gravity survey along an 11 km traverse in a north-south direction across the structure shows a negative gravity anomaly of over 6 mgal.
