ORDOVICIAN:

ORDOVICIAN Baltica Early moved south Late - moved north toward Laurentia

ORDOVICIAN:

ORDOVICIAN Baltica Early moved south Late - moved north toward Laurentia Oceans Early regression Mid- to Late transgressions again

SILURIAN:

SILURIAN Baltica - to equator and headed north

SILURIAN:

SILURIAN Baltica - to equator and headed north Laurentia - rotating

SILURIAN:

SILURIAN Baltica - to equator and headed north Laurentia rotating Taconic Mountains eroding Acadian-Caledonian Orogeny beginning

SILURIAN:

SILURIAN Baltica - to equator and headed north Laurentia rotating Taconic Mountains eroding Acadian-Caledonian Orogeny beginning Siberia - left equator - headed north

LATE PALEOZOIC:

LATE PALEOZOIC Permian 245-286 Pennsylvanian 286-320 Mississippian 320-362 Devonian 362-418

LATE DEVONIAN:

LATE DEVONIAN Baltica and Laurentia collision continued forming Laurussia

LATE DEVONIAN:

LATE DEVONIAN Baltica and Laurentia collision continued forming Laurussia Siberia closing on north Laurussia Ellesmere Orogeny (Franklinian)

LATE DEVONIAN:

LATE DEVONIAN Baltica and Laurentia collision continued forming Laurussia Siberia closing on north Laurussia Ellesmere orogeny (Franklinian) Antler orogeny in western N. America

ANTLER OROGENY:

ANTLER OROGENY Antler Orogeny Idaho, Nevada, (California)

ANTLER OROGENY:

ANTLER OROGENY Antler Orogeny Idaho, Nevada, (California) Collisions of N. America with island arcs in Devonian-Mississippian (Pennsylvanian)

MISSISSIPPIAN:

MISSISSIPPIAN Mississippian used in N. America - lower Carboniferous in other places

MISSISSIPPIAN:

MISSISSIPPIAN Mississippian used in N. America - lower Carboniferous in other places widespread epicontinental seas

MISSISSIPPIAN:

MISSISSIPPIAN Mississippian used in N. America - lower Carboniferous in other places widespread epicontinental seas uplift again in Appalachian area (Baltica)

MISSISSIPPIAN:

MISSISSIPPIAN Mississippian used in N. America - lower Carboniferous in other places widespread epicontinental seas uplift again in Appalachian area (Baltica) Antler Orogeny continued from Devonian - more island arcs

MISSISSIPPIAN:

PENNSYLVANIAN:

PENNSYLVANIAN Alleghenian Orogeny - continued uplift of Appalachian area

PENNSYLVANIAN:

PENNSYLVANIAN Alleghenian Orogeny - continued uplift of Appalachian area Ouachita Orogeny - syncline in Oklahoma, Arkansas, Texas - collision produced mountains in Pennsylvanian

PENNSYLVANIAN:

PENNSYLVANIAN Alleghenian Orogeny - continued uplift of Appalachian area Ouachita Orogeny - syncline in Oklahoma, Arkansas, Texas - collision produced mountains in Pennsylvanian deltas and coal swamps in eastern North America and Europe

COAL DEPOSITION:

COAL DEPOSITION sand, mud, etc. from Appalachian and Ouachita Mountains

COAL DEPOSITION:

COAL DEPOSITION sand, mud, etc. from Appalachian and Ouachita Mountains numerous small oscillations in sea level

COAL DEPOSITION:

COAL DEPOSITION sand, mud, etc. from Appalachian and Ouachita Mountains numerous small oscillations in sea level coal formed from accumulated vegetation in lagoons and coastal swamps - similar to present day Dismal Swamp (VA, NC) or backwaters in LA

COAL DEPOSITION:

COAL DEPOSITION forests covered swampy land - vegetation died, sometimes killed by flooding

COAL DEPOSITION:

COAL DEPOSITION forests covered swampy land plants covered with water and sediment - low oxygen - protected from decomposition

COAL DEPOSITION:

COAL DEPOSITION forests covered swampy land plants covered with water and sediment - low oxygen - protected from decomposition carbonization or distillation - leaves carbon

COAL DEPOSITION:

COAL DEPOSITION forests covered swampy land plants covered with water and sediment - low oxygen - protected from decomposition carbonization or distillation - leaves carbon (plant peat lignite bituminous anthracite)

GLACIATION IN GONDWANA:

GLACIATION IN GONDWANA in South America at least 10 glacial episodes (up to 17 episodes)

GLACIATION IN GONDWANA:

GLACIATION IN GONDWANA in South America at least 10 glacial episodes (up to 17 episodes) slow movement of Gondwana over South Pole

GLACIATION IN GONDWANA:

GLACIATION IN GONDWANA in South America at least 10 glacial episodes (up to 17 episodes) slow movement of Gondwana over South Pole Africa - Late Devonian and Carboniferous South America - Mississippian - Permian Australia - Permian

CORDILLERA:

CORDILLERA western North America eastward moving island arcs collide

CORDILLERA:

CORDILLERA western North America eastward moving island arcs collide Mississippian - Antler Orogeny Permian and later - Sonoma Orogeny
