Turn off the North America Batholiths overlay and the Henry Mountains Laccolith Complex polygon, and then turn on and double-click the Problem 5 placemark to zoom down to the south flank of the Mt. Hillers laccolith. The laccolith is composed of gray andesite that has intruded into Mesozoic-age sedimentary rocks and upturned them on the flanks of the intrusion (recall that laccoliths are concordant intrusions that cause the overlying sedimentary layers to fold up in a blister or mushroom-shaped pattern). The sedimentary rocks over the intrusion have been eroded. The Problem 5 placemark highlights a tabular intrusion from the main laccolith that is parallel/concordant to the upturned sedimentary layers. What kind of intrusion is this?
