Chapter 2 Paleozoic Stratigraphy of the Grand Canyon
CHAPTER 2 PALEOZOIC STRATIGRAPHY OF THE GRAND CANYON PAIGE KERCHER INTRODUCTION The Paleozoic Era of the Phanerozoic Eon is defined as the time between 542 and 251 million years before the present (ICS 2010). The Paleozoic Era began with the evolution of most major animal phyla present today, sparked by the novel adaptation of skeletal hard parts. Organisms continued to diversify throughout the Paleozoic into increasingly adaptive and complex life forms, including the first vertebrates, terrestrial plants and animals, forests and seed plants, reptiles, and flying insects. Vast coal swamps covered much of mid- to low-latitude continental environments in the late Paleozoic as the supercontinent Pangaea began to amalgamate. The hardiest taxa survived the multiple global glaciations and mass extinctions that have come to define major time boundaries of this era. Paleozoic North America existed primarily at mid to low latitudes and experienced multiple major orogenies and continental collisions. For much of the Paleozoic, North America’s southwestern margin ran through Nevada and Arizona – California did not yet exist (Appendix B). The flat-lying Paleozoic rocks of the Grand Canyon, though incomplete, form a record of a continental margin repeatedly inundated and vacated by shallow seas (Appendix A). IMPORTANT STRATIGRAPHIC PRINCIPLES AND CONCEPTS • Principle of Original Horizontality – In most cases, depositional processes produce flat-lying sedimentary layers. Notable exceptions include blanketing ash sheets, and cross-stratification developed on sloped surfaces. • Principle of Superposition – In an undisturbed sequence, older strata lie below younger strata; a package of sedimentary layers youngs upward. • Principle of Lateral Continuity – A layer of sediment extends laterally in all directions until it naturally pinches out or abuts the walls of its confining basin. -

Bryce Canyon National Park
Lees Ferry, Arizona), White (which surround Utah Zion Canyon), Gray and Pink. Most of the Grand Staircase is now contained within the BLM-managed Grand Staircase - Escalante National Monument. The rocks that give Bryce Canyon its distinctive colors are members of the Claron Formation, a mixed Highlights limestone/sandstone layer, and are also found exposed, with similarly intricate forms, in other nearly locations such as Red Canyon and Cedar Breaks. Erosion: Water is responsible for creating the rock shapes in Bryce Canyon National Park. Rain and melting snow flowing down the Pink Cliffs towards the Paria River form ridges, or fins, which subsequently erode into the spires, pinnacles and other shapes (collectively known as ‘hoodoos’) which are left standing. In time these too erode, and the whole process moves very gradually westwards as more of the cliff is slowly worn away. During the long, cold winters, the cliffs are further weakened by freezing water Bryce Canyon National Park expanding in cracks, resulting in more erosion when the ice Bryce Canyon National Park does not contain one main thaws in spring. canyon, but rather a dozen smaller ravines eroded into the east side of a ridge running approximately north-south at Bryce Canyon Trails: As with most national parks, the best the edge of the Paunsaugunt Plateau in southwest Utah.

Michael Kenney Paleozoic Stratigraphy of the Grand Canyon
Michael Kenney Paleozoic Stratigraphy of the Grand Canyon The Paleozoic Era spans about 250 Myrs of Earth History from 541 Ma to 254 Ma (Figure 1). Within Grand Canyon National Park, there is a fragmented record of this time, which has undergone little to no deformation. These still relatively flat-lying, stratified layers, have been the focus of over 100 years of geologic studies. Much of what we know today began with the work of famed naturalist and geologist, Edwin Mckee (Beus and Middleton, 2003). His work, in addition to those before and after, have led to a greater understanding of sedimentation processes, fossil preservation, the evolution of life, and the drastic changes to Earth’s climate during the Paleozoic. This paper seeks to summarize, generally, the Paleozoic strata, the environments in which they were deposited, and the sources from which the sediments were derived. Tapeats Sandstone (~525 Ma – 515 Ma) The Tapeats Sandstone is a buff colored, quartz-rich sandstone and conglomerate, deposited unconformably on the Grand Canyon Supergroup and Vishnu metamorphic basement (Middleton and Elliott, 2003). Thickness varies from ~100 m to ~350 m depending on the paleotopography of the basement rocks upon which the sandstone was deposited. The base of the unit contains the highest abundance of conglomerates. Cobbles and pebbles sourced from the underlying basement rocks are common in the basal unit. Grain size and bed thickness thins upwards (Middleton and Elliott, 2003). Common sedimentary structures include planar and trough cross-bedding, which both decrease in thickness up-sequence. Fossils are rare but within the upper part of the sequence, body fossils date to the early Cambrian (Middleton and Elliott, 2003). -
A Conceptual Hydrogeologic Model for Fossil Springs, Western
A CONCEPTUAL HYDROGEOLOGIC MODEL FOR FOSSIL SPRINGS, WESTERN MOGOLLON RIM, ARIZONA: IMPLICATIONS FOR REGIONAL SPRINGS PROCESSES By L. Megan Green A Thesis Submitted in Partial Fulfillment of the Requirements for the Degree of Master of Science in Geology Northern Arizona University May 2008 Approved: _________________________________ Abraham E. Springer, Ph.D., Chair _________________________________ Roderic A. Parnell, Jr., Ph.D. _________________________________ Paul J. Umhoefer, Ph.D. ABSTRACT A CONCEPTUAL HYDROGEOLOGIC MODEL FOR FOSSIL SPRINGS, WEST MOGOLLON MESA, ARIZONA: IMPLICATIONS FOR REGIONAL SPRINGS PROCESSES L. Megan Green Fossil Springs is the largest spring system discharging along the western Mogollon Rim in central Arizona and is a rare and important resource to the region. The purpose of this study was to gain a better understanding of the source of groundwater discharging at Fossil Springs. This was accomplished by (1) constructing a 3-D digital hydrogeologic framework model from available data to depict the subsurface geology of the western Mogollon Rim region and (2) by compiling and interpreting regional structural and geophysical data for Arizona’s central Transition Zone. EarthVision, a 3-D GIS modeling software, was used to construct the framework model. Two end-member models were created; the first was a simple interpolation of the data and the second was a result of geologic interpretations. The second model shows a monocline trending along the Diamond Rim fault. Both models show Fossil Springs discharging at the intersection of the Diamond Rim fault and Fossil Springs fault, at the contact between the Redwall Limestone and Naco Formation. The second objective of this study was a compilation of regional data for Arizona’s central Transition Zone.
