By: Lehi F. Hintze and Bart J. KowallisFrom page iii, About this Book: This is a completely revised (with color added) version of the most widely used book on the geology of Utah in print. This book supplements the published geologic maps of Utah (Hintze, 1980, 1997, 2000f) by providing a third dimension, thickness, to the many map units whose areal extent is shown on the maps. The book also summarizes how these map units relate to Earth's plate tectonic system.
Much new information regarding Utah's geologic past has been discovered in the years since the first edition of this book was published. This version of the book includes information on our understanding of plate tectonics, our knowledge of Precambrian rocks, concepts and ages of volcanic events in the last 30 million years, this history of Lake Bonneville within the last 30,000 years and the activity of the Wasatch Fault within the last 5,000 years. Several new stratigraphic charts have been added.
The book is directed primarily toward students in geology, but professional geologists working in Utah will find the stratigraphic and correlation charts useful. Other interested persons will find the broad sweep of Utah's geologic history fascinating.
It is with a deep sense of loss that we acknowledge the death of Dr. Lehi F. Hintze on July 1, 2014, at the age of 93.
