Paperback. Condizione: New. Print on Demand. This book approaches the long-standing debate over the geological origins of the front of the Bitterroot Range, grappling with a mystery that has attracted speculation since at least 1899. The author incorporates both field and laboratory data to support his conclusion that the banded gneiss rock of the Bitterroot Range front is not the result of faulting as previously hypothesized but rather a granitized sedimentary rock, likely part of the region's Ravalli Group. Although a similar conclusion was reached by another scientist in 1935, this book presents new evidence and delves into the regional geology to firmly establish the sedimentary origins of this rock. The author emphasizes that, due to the rock's prolonged history, many of its original sedimentary features have been obscured by igneous influence yet remain visible for the keen observer in the rock's banding and composition. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
