However, in this formation they are abundant and of forms that had already developed through a substantial part of all evolution that has taken place during the history of the earth. During Middle and Late Devonian time the Acadian Orogeny, with the main uplift to the northeast, resulted in a further source for the predominantly clastic marine deposits of these epochs. [2][3] Although Rodinia began to break up between 850 and 750 million years ago, it was not until about 600 million years ago that the Iapetus Ocean began to open up between Laurentia and its neighbors along the region uplifted during the Grenville orogeny. Important lake deposits, predominantly clay, were thus laid down in the Monongahela River basin. The Taconic orogeny near the end of Ordovician time formed a high mountainous area east of West Virginia. Permission to reproduce this material is granted if acknowledgment is given to the West Virginia Geological and Economic Survey.

Early in the succeeding Pennsylvanian Period, the area dropped to near sea level and for more than 50 million years continued to sink at about the same rate that deposition was taking place.

The Appalachian Orogeny began roughly 270 to 225 million years ago, building the present-day Appalachian Mountains. These highlands formed the main source of sediments for the succeeding Silurian Period and part of the Devonian Period. The basement rock of West Virginia was formed during the Grenville orogeny, approximately 1,140 to 980 million years ago, when the land mass today known as Laurentia, the ancestral North American craton, collided with other land masses to produce the supercontinent known as Rodinia.

Divergence of the New River system that formerly drained northwestward caused the deposition of similar deposits in the old Teays River channel between Charleston and Huntington. Most of the state was uplifted, important deposition of sediments ceased, and a gradual process of erosion commenced. Drainage was diverted westward into the Ohio River system. Michael.
