Abstract. The Appalachian chain is a Paleozoic megastructure, bordering eastern North America.

On land the exposed part of the chain stretches more than 3, km from Newfoundland in the northeast to Alabama in the southwest (Fig. To the northwest the chain is adjacent to the Laurentian craton of Precambrian rocks.

This volume contains 36 original papers reporting the results of research performed throughout nearly the entire length and breadth of the Appalachian region, including all major provinces and geographical areas.

The Appalachian Mountains, often called the Appalachians, are a system of mountains in eastern North America. The Appalachians first formed roughly million years ago during the Ordovician Period. They once reached elevations similar to those of the Alps and the Rocky Mountains before experiencing natural erosion.

The Appalachian chain is a barrier to east–west travel, as it forms a Peak: Mount Mitchell. Appalachian Mountains - Appalachian Mountains - Geology: The Appalachians are among the oldest mountains on Earth, born of powerful upheavals within the terrestrial crust and sculpted by the ceaseless action of water upon the surface.

The two types of rock that characterize the present Appalachian ranges tell much of the story of the mountains’ long existence.

Rocks that originated within the peri-Laurentian oceanic realm of Iapetus are widespread and constitute the Notre Dame and Dashwoods subzones (Williams et al. ).
