Paperback. Condición: New. Print on Demand. This book examines the ancient volcanic rocks found in the South Mountain range of Pennsylvania. The author's findings challenge previous assumptions about their nature and age, identifying them as volcanic in origin and placing their formation in the early Paleozoic era. Through detailed analysis of the rocks' petrography and structure, the author argues that these volcanic formations underwent significant changes over time, including devitrification, which altered their original glassy texture. The book provides a valuable contribution to the understanding of the geological history of the region and the nature of ancient volcanic activity.
