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. -

Characterization and Hydraulic Behaviour of the Complex Karst of the Kaibab Plateau and Grand Canyon National Park, USA
Characterization and hydraulic behaviour of the complex karst of the Kaibab Plateau and Grand Canyon National Park, USA CASEY J. R. JONES1, ABRAHAM E. SPRINGER1*, BENJAMIN W. TOBIN2, SARAH J. ZAPPITELLO2 & NATALIE A. JONES2 1School of Earth Sciences and Environmental Sustainability, Northern Arizona University, NAU Box 4099, Flagstaff, AZ 86011, USA 2Grand Canyon National Park, National Park Service, 1824 South Thompson Street, Flagstaff, AZ, 86001, USA *Correspondence: [email protected] Abstract: The Kaibab Plateau and Grand Canyon National Park in the USA contain both shallow and deep karst systems, which interact in ways that are not well known, although recent studies have allowed better interpretations of this unique system. Detailed characterization of sinkholes and their distribution on the surface using geographical information system and LiDAR data can be used to relate the infiltration points to the overall hydrogeological system. Flow paths through the deep regional geological structure were delineated using non-toxic fluorescent dyes. The flow character- istics of the coupled aquifer system were evaluated using hydrograph recession curve analysis via discharge data from Roaring Springs, the sole source of the water supply for the Grand Canyon National Park. The interactions between these coupled surface and deep karst systems are complex and challenging to understand. Although the surface karst behaves in much the same way as karst in other similar regions, the deep karst has a base flow recession coefficient an order of magnitude lower than many other karst aquifers throughout the world. Dye trace analysis reveals rapid, con- duit-dominated flow that demonstrates fracture connectivity along faults between the surface and deep karst. -

Geochronology, Geology, and Listric Normal Faulting of the Vulture Mountains, Maricopa County, Arizona
Arizona Geological Society Digest, Volume XII, 1980 89 Geochronology, Geology, and Listric Normal Faulting of the Vulture Mountains, Maricopa County, Arizona by WA. Rehrigi, M. Shafiqullah2, and P.E. Damon2 Abstract Geologic mapping and geochronologic studies in the Vulture Mountains near Wickenburg, Arizona, have led to the recognition of a large, northeast-trending batholith of 68.4-m.y. age that intrudes complex gneissic and granitic rocks of probably Precambrian age. Over- lying the denuded crystalline terrane is a sequence of late Oligocene to Miocene ( .'26 to 16 m.y.) volcanic rocks (vitrophyres, ash-flow tuffs, welded tuffs, breccias, agglomerates, and lava flows) that vary locally. Nearby source areas are suggested. A swarm of north- to north-northwest-trending porphyritic dikes intrudes the volcanics and crystalline basement. Overlying this volcanic sequence in angular unconformity is a thin section of basal conglom- erate and basalt lava flows dated at 13.5 m.y. B.P. The older, tuffaceous sequence is generally calc-alkalic but with a high proportion of rhyolites that are exceptionally rich in potassium and silica. These silicic units are peral- kaline or nearly so, and those with K20/Na2O >3 are ultrapotassic. Initial strontium ratios average 0.7081, whereas an initial ratio for the younger basalt sequence is significantly lower at 0.7054. The silicic volcanics have been severely tilted on multiple, low-angle listric normal faults. The youngest basalt flows are relatively flat lying and postdate this deformation. By geo- logic and radiometric criteria, the transition from tilted silicic volcanics to untilted basalts occurred between about 16 and 14 m.y. -

Miller Open-File Report 94-15 ARIZONA GEOLOGICAL SURVEY TUCSON, ARIZONA NOVEIVIBER, 1994 This report is preliminary and lias not been edited or reviewed for conformity with Arizona Geological Survey standards INTRODUCTION The principal geologic feature of the Big Hom and Belmont Mountains is a complexly faulted and tilted series of mostly Miocene volcanic rock that record a period of Middle Tertiary magmatism and extension. These volcanic rocks vary widely in composition, but basaltic and rhyolitic rocks are most abundant (Figure 1). Intrusive equivalents of these volcanics exposed in the Belmont Mountains are dominantly granitic.

It has occupied a criti- cal structural position in the western Cordillera since Mesozoic time. In the Cretaceous through early Tertiary, it stood just east and north of major fold and thrust belts and also marked the northern end of a broad, gently (~15o) north-plunging uplift (Kingman arch) that extended southeastward through much of central Arizona. Mesozoic and Paleozoic strata were stripped from the arch by northeast-flowing streams. Peraluminous 65 to 73 Ma granites were emplaced at depths of at least 10 km and exposed in the core of the arch by earliest Miocene time. Calc-alkaline magmatism swept northward through the northern Colorado River extensional corridor during early to middle Miocene time, beginning at ~22 Ma in the south and ~12 Ma in the north. -

Xeroriparian Systems Used by Desert Mule Deer in Texas And Arizona1 Paul R. Krausman2 , Kurt R. Rautenstrauch3 and Bruce D. Leopold4 Abstract.--We examined desert mule deer (Odocoileus hemionus crooki) occurrance in xeroriparian systems in Arizona and Texas. Most deer in Arizona were located in washes. Most deer in Texas were located between washes. Xeroriparian areas are important habitat components for desert mule deer when they provide forage, thermal cover and travel lanes.
