What is an intrusion and what causes it? What is a sill and dike?
What is An intrusion is a layer of igneous rock formed when magma from under the sedimentary rock is injected into the cracks and fissures of the sedimentary rock. A sill are the "veins" of igneous rock that run in the same direction of the sedimentary strata while a dike would be a "vein" running perpendicular to the sedimentary strata.
