   What is the geology of Shenandoah National Park?

   • Appalachian Mountains To really understand the geology of Shenandoah National Park, we first have to look at the park’s setting. It is located in the Appalachian Mountains, an ancient mountain range in the eastern United States that started to form roughly 470 million years old, when separate landmasses started to converge.

   What is a metasedimentary rock in Shenandoah National Park?

   • The sedimentary rocks experienced metamorphism andthe rocks of the Chilhowee Group are called metasedimentary rocks. Today in Shenandoah National Park, the rocks of the Chilhowee Group form steep ridges and hollows that are covered in eroded rock debris called talus.

   Why is Shenandoah National Park rounded?

   • Shenandoah National Park is nestled within the Blue Ridge province of the Appalachian Mountains, which extends from Pennsylvania southward. The Blue Ridge Mountains are more rounded than those farther west. This is because these are some of the older mountains in the Appalachian Range, and there has been more time for erosion to occur.

   About half a billion years ago, the rocks that now make up the Shenandoah Valley solidified from ancient tidal flat sediments into vast, horizontal layers of limestone, shale, sandstone, and dolomite.

   The Valley’s abundant limestone is evidence that the area was once under ocean water, long before the tectonic plates collided. Limestone forms in warm, shallow seas when generations of tiny sea creatures die and accumulate on the ocean floor, later to compress into solid rock.

   Many rocks and minerals occupy the Shenandoah Valley besides limestone. Other sedimentary rocks in the region are sandstone, shale, and coal. There are igneous rocks like granite, gabbro, and basalt, and metamorphic rocks like slate, gneiss, and quartzite. Manganese, iron ores, zinc, lead, sulfur, gypsum, and pyrite are relatively common Shenandoah...
