Description

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Prior to one billion years ago, the geologic history of West Virginia is obscure. The oldest evidences of life found in West Virginia occur in rocks about 600 million years old, in the Antietam Formation of Lower Cambrian age. The oldest exposed rock, the Catoctin greenstone, began to form between about 1,100 and 800 million years ago. Lava was deposited in the extreme eastern part of the State. About 300 million years later, by the end of Cambrian time, a shallow sea covered essentially all of West Virginia. Marine deposition took place throughout most of this and the succeeding Ordovician Period. The Taconic orogeny near the end of Ordovician time formed a high mountainous area east of West Virginia. Near the end of Devonian time, the sea was rapidly retreating westward and the continental red beds of the Hampshire Formation were being deposited over most of the State.show more
