1 UNIVERSITY OF SOUTH ALABAMA GY 112: Earth History Lecture 36: Plio-Pleistocene Geology Instructor: Dr. Douglas W. Haywick
2 Last Time A) Cenozoic Overview and Tectonics Western North American tectonic provinces Plateaus and canyons
3 Cenozoic Time Frame Phanerozoic Era Cenozoic Mesozoic Paleozoic Years (0 to 65 MA) (65 to 245 MA) (245 to 550 MA)
4 Cenozoic Time Frame Period Quaternary (1.6-0 MA) Cenozoic Tertiary ( MA) Epoch Holocene (10,000 0 years) Pleistocene (1,600,000 10,000 years) Pliocene ( MA) Miocene ( MA) Oligocene (37-24 MA) Eocene (58-37 MA) Paleocene (65-58 MA) Introducing the Epochs (the smallest common divisions of geological time)
5 Mammals diversified Cenozoic Life Most modern orders present by Early Eocene
6 Cenozoic Life Primates modernized in Oligocene Monkeys Apelike primates Aegyptopithecus
7 Cenozoic Life Mammalian carnivores evolved by mid- Paleogene
8 Cenozoic Life Spread of C 4 grasses C 4 plants Incorporate more carbon 13 than C 3 grasses Five times more silica Wears down teeth of grazers
9 Cenozoic Deep Ocean Currents Chalk Board
10 Cenozoic Tectonic Events Final breakup of Gondwanna (Australia separated from Antarctica in the Latest Paleocene earliest Eocene epochs) India began to collide with Asia forming the Himalayan Mountain Range (Oligocene to Recent) Africa started to shift northward, gradually sliding under Europe and uplifting the Alps (Oligocene to Recent) Continued westward movement of North America and South America formed an on again off again land bridge between the two continents. This gave rise to some interesting animal exchanges (see evolutionary events below). North American orogenies become dominated by strike-slip faulting and uplift. Mountain building in the northern part of the Cordilleran mountains (mostly Canada) slows down stop during the Oligocene. Activity shifts to the southern part of the mountain chain (Colorado, Nevada etc.). Major late Tertiary flood basalt eruptions occur in Oregon and Washington state. Hot spot volcanism occurs in the area of Yellowstone (Pliocene to present). Composite volcanic eruptions (some incredibly explosive) periodically occurred and still do (e.g., Mt St Helen s).
11 Tectonic Events Cordilleran region Laramide orogeny New tectonic style
12 Cenozoic Tectonics Eocene Tectonic elements:
13 Cenozoic Tectonics Miocene Tectonic elements:
14 Cenozoic Tectonics Modern Tectonic elements:
15 Cenozoic Tectonics As North America drifts to the WNW, we eventually run over the leading edge of the East Pacific Rise Eocene
16 Cenozoic Tectonics As North America drifts to the WNW, we eventually run over the leading edge of the East Pacific Rise Oligocene
17 Cenozoic Tectonics Uplift As North America drifts to the WNW, we eventually run over the leading edge of the East Pacific Rise And uplift now affects the SW Today
18 Cenozoic Tectonics Key tectonic elements: 1) Farallon Plate (east of East Pacific Rise; east drift) 2) Pacific Plate (west of East Pacific Rise; west drift)
19 Cenozoic Tectonics Key tectonic elements: 1) Farallon Plate (east of East Pacific Rise; east drift) 2) Pacific Plate (west of East Pacific Rise; west drift) 3) Juan de Fuca Plate (east of East Pacific Rise; east drift) 4) Cocos Plate (east of East Pacific Rise; east drift)
20 Cenozoic Tectonics Key tectonic style: simple uplift Laramide Orogeny
21 Cenozoic Tectonics Important Basins 1) Green River Basin 2) Uinta Basin 3) Washakie/Sandwash Basins 4) Piceance Creek Basin All are rich in oil shale
22 Cenozoic Tectonics 1) Basin and Range
23 Cenozoic Tectonics 1) Basin and Range 2) Colorado Plateau 3) Columbia River Plateau Basin and Range
24 Cenozoic Tectonics Basin and Range: Uplifted deformed strata

30 Cenozoic Tectonics Columbia River Plateau: Basalt lava flow covered terrain
31 Cenozoic Tectonics 1) Basin and Range 2) Colorado Plateau 3) Columbia River Plateau 4) Rio Grande Rift
32 Cenozoic Tectonics Rio Grande Rift: Uplifted rifting strata
33 Today s Agenda A) Finish off Cenozoic Tectonics B) Cenozoic temperature and sea level shifts C) Plio-Pleistocene Glaciations (Milankovitch Orbital Variations) D) Sea level changes in our own back yard Web notes 37
34 Cenozoic Tectonics Other interesting Cenozoic (Recent) Tectonics: 1) Yellowstone
35 Cenozoic Tectonics Other interesting Cenozoic (Recent) Tectonics: 1) Yellowstone 2) Crater Lake
36 Cenozoic Tectonics Other interesting Cenozoic (Recent) Tectonics: 1) Yellowstone 2) Crater Lake 3) Composite Volcanoes
37 Cenozoic Tectonics
38 Plio-Pleistocene Is most notable for rapid, short duration shifts in temperature and ice volume.
39 Plio-Pleistocene Is most notable for rapid, short duration shifts in temperature and ice volume.
40 Plio-Pleistocene Is most notable for rapid, short duration shifts in temperature and ice volume. Why?
41 Plio-Pleistocene Glaciations started around 5 million years ago. Isthmus of Panama Emplaced M years ago Started modern circulation Gulf stream carries salty Atlantic north Cools, sinks Oceanic conveyor belt High latitudes cool
42 Milankovitch Cycles Three major changes in Earth s orbit are linked to glacial oscillations Eccentricity Obliquity Precession
43 Milankovitch Cycles When taken together, the 3 cycles are capable of dropping temperatures globally
44 Milankovitch Cycles When taken together, the 3 cycles are capable of dropping temperatures globally. These cycles have been confirmed via stable isotope analysis of deep sea foraminifera (ice volume).
45 Paleoclimate Phases We now recognize two major Earth climatic phases 1) Greenhouse Earth (no continental glaciers present) 2) Icehouse Earth (continental glaciers present)
46 Paleoclimate Phases Icehouse Earths fluctuate between 2 stages: a) Glacial stage (18 KA) b) Interglacial stage (Today)
47 The Present Ice House Earth Glacial/ interglacial stage Name of stage Time frame interglacial Holocene 0-10 KA glacial Wisconsinian KA interglacial Sangamon KA glacial Illinoisan KA interglacial Yarmouth KA glacial Kansan KA interglacial Aftonian KA glacial Nebraskan > 500 KA
48 The Ice Age Glacial Maximum Extent of continental glaciation Several lines of evidence 1) Erratic boulders
49 The Ice Age 2) Glacial till and basins associated with glaciation 3) Depression of the land Hudson Bay
50 The Ice Age Lowering of sea level Exposed continental shelves
51 The Ice Age Migration of species Mammals crossed Bering Strait on land corridors Vegetation changed in response to global changes
52 The Ice Age Ocean circulation changed during glaciation Glacier in NJ Tundra in Washington, D.C.
53 The Ice Age Great lakes Last glacial maximum 35,000-10,000 years ago Wisconsin Stage Remained when ice sheets melted back
54 The Ice Age Climate impacts were felt globally Steepened temperature gradients Increased aridity Exception: Great Basin Lakes Great Salt Lake
55 The Ice Age Climate impacts were felt globally Sahara expanded Rain forests restricted Isolated gorilla species
56 End of the Ice Age Glaciers began to retreat around 15,000 years ago Waters drained to lakes Sea level rose Tundra shifted northward Deciduous trees migrated northward
57 Transgression Sea Level Lagoonal complexes transgress over coastal plain sediments Regression High sediment supply is causing coast to move offshore Texas
58 In southern Alabama, regressions caused the shoreline to shift 100 miles south. Base level of rivers dropped by 300 feet. Sea Level The Mobile River carved a canyon, the remnants of which are still exposed along the Eastern Shore
59 In southern Alabama, regressions caused the shoreline to shift 100 miles south. Base level of rivers dropped by 300 feet. Sea Level The Mobile River carved a canyon, the remnants of which are still exposed along the Eastern Shore
