Geology The Scene Today Visitors to Saguaro National Park are often impressed by the rugged mountain landscapes and the saguaro forests of the Sonoran Desert. Major landforms include dry washes and large arroyos, which fill quickly after rainstorms; alluvial fans at the mouths of canyons, which combine to form long, sweeping slopes known as bajadas (ba-HAH-da); and pediments, which form where eroded bedrock extends out from the mountains. The present day scene has been in the making for millions of years. Although imperceptible to our eye, the desert is constantly changing. The ongoing story is told by the rocks. The geology of the Tucson area is complex and the interpretation of the physical evidence is under debate. The Rincon and Tucson Mountains offer very different geologic histories. Visitors ask questions, such as what type of rock is present or how the mountains came to be. Geologists ask the same questions with more specific interest in how the different rocks came together into complex yet systematically arranged mountain ranges. The Building Blocks Rincon Mountain District General Most of the mountains of the southwest have been uplifted on near-vertical faults about 15 million years ago (MYA). However, the Rincon Mountains, along with the Catalinas and Tortolitas, are part of a 3-humped core complex formed earlier. The highest peak in the Rincons is Mica Mountain. It is 8,666 feet in elevation and supports vegetation of the trans-Canadian zone, that is Ponderosa pine and spruce.

Anupma Gupta Assistant Professor Biosphere 2 Center, Columbia University Box 689, Oracle, AZ 85623 USA agupta@bio2.columbia.edu Education Research Interests Anu is a structural geologist interested in the growth of faults, the geologic history around plate boundaries, and earthquake hazards. Her research has taken her from rock quarries in North Carolina, to the site of a future ocean basin in East Africa, to the world of digital elevation models and geographical information systems. Her teaching interests include global change, hydrogeology, and field geology. Prior to her arrival at Biosphere 2, Anu was a faculty member for a Keck Geology Consortium research project in the Coast Mountains of British Columbia.

Putah and Cache Entering Geology of Putah-Cache: Introduction Eldridge M. Moores and Judith E. Moores Plate Boundaries The Putah-Cache bioregion lies within the southeastern part of the northern California Coast Ranges. The California Coast Ranges are internationally famous for spectacular examples of rocks that were deposited and/or modified during ancient and continuing plate boundary activities along the West Coast of the U.S. The Putah-Cache rocks are part of this world-class plate tectonic exhibit. The theory of Plate Tectonics holds that three kinds of boundaries (also called margins) exist between plates: Divergent Boundaries, where plates are moving apart and new ocean crust and mantle is formed by upwelling of new material from the interior; Convergent Boundaries, also called Subduction Zones, where two plates approach one another, and one descends beneath the other (as this happens, some material melts and rises to form granitic bodies, as in the Sierra Nevada, or volcanoes such as Mt. Lassen, Mt. Pinatubo, or Mt. Shasta); and Transform Fault or Conservative Boundaries

Structural Geology Lab Quick Access Main Page Minerals Igneous Sedimentary ... Hydrogeology Last Modified: Overheads shown in Lab Structural Geology is perhaps one of the hardest subjects for beginning geology students to learn. It deals with geologic structures (faults and folds) that form when stresses (tension, compression, shear) act upon a body of rock. The difficulty is that it requires that the student think in 3-D which is a difficult skill to learn. However, there is hope! Knowing a few simple rules (and a lot of terminology) can allow even the beginning geologist to handle some rather complex structural problems. Let's get to it!
