Document Summary
A surface separating different types of rocks is called: a contact. The major difference between volcanic and plutonic igneous rocks is: where they solidify. Which is not a fine-grained rock type? granite. By definition, stocks differ from batholiths in: size. Fragments of country rock that are distinct from the body of igneous rocks in which they are enclosed: xenoliths. Which of the following minerals is part of bowen"s continuous series? plagioclase feldspar. Which of the following minerals is part of bowen"s discontinuous series? olivine, biotite, pyroxene. The difference in minerals among plutonic rocks is caused by: magmatic differentiation, different chemical compositions, different crystallization temperatures. An example of a hot spot where a hot mantle plume is currently lying at a shallow depth beneath the continental crust is: yellowstone national park. Basalt is most often associated with what type of plate boundary? divergent plate boundaries.
