What is an igneous intrusion? - Socratic
2016年4月14日 · Molten rock called "magma" that intrudes or invades shallower rocks. Igneous intrusions consist of molten magma that rises up from the mantel (because they have less density) and intrude into other rocks. They are of two types: 1) intrusive and 2) extrusive. Intrusive rocks move upward in the crust but cool before they break the surface; while extrusive rocks …

Solved The igneous intrusion (V) was examined and scientists
Question: The igneous intrusion (V) was examined and scientists found that this rock had about 25% of the overall Uranium-235 left in the composition of the rock. This fact helps scientists determine how old the intrusion is and in turn will give clues about the age of the rock layers around and beneath the intrusion.
