Explore the geological connections between sedimentation patterns in the Western Interior Basin and the mid-Cretaceous Peninsular Ranges orogeny in this 20-minute conference presentation. Learn from Robert S. Hildebrand's virtual talk delivered at the national GSA Meeting in Portland, Oregon in 2021, where he examines how mountain-building processes influenced sedimentary deposition across western North America during the Cretaceous period. Discover the mechanisms linking orogenic activity in the Peninsular Ranges to broader sedimentary basin development, gaining insights into the complex interplay between tectonics and sedimentation during this critical period in North American geological history.
