Palaeo geography

  1. 1. British Isles
  2. 2. Lower Palaeozoic i) Lower Palaeozoic - Britain was south of the equator: evidence for plate collision from Caledonian orogenic belt. turbidites granites, regional metamorphism, thrusts, folds
  3. 3. Lower Palaeozoic i) Lower Palaeozoic - Britain was south of the equator: evidence for plate collision from Caledonian orogenic belt. turbidites granites, regional metamorphism, thrusts, folds
  4. 4. Lower Palaeozoic Ordovician i) Lower Palaeozoic - Britain was south of the equator: evidence for plate collision from Caledonian orogenic belt. turbidites granites, regional metamorphism, thrusts, f olds
  5. 5. Lower Palaeozoic Silurian i) Lower Palaeozoic - Britain was south of the equator: evidence for plate collision from Caledonian orogenic belt. turbidites granites, regional metamorphism, thrusts, folds
  6. 6. Upper Palaeozoic (ii) Upper Palaeozoic - Britain drifts across the equator. tropical seas [limestone] swamp forest [deltas, coal formation] desert conditions 15oN [wind-formed dune-bedded sandstone, evaporites, breccia] Devonian
  7. 7. Upper Palaeozoic (ii) Upper Palaeozoic - Britain drifts across the equator. tropical seas [limestone] swamp forest [deltas, coal formation] desert conditions 15oN [wind-formed dune-bedded sandstone, evaporites, breccia] Carboniferous
  8. 8. Upper Palaeozoic (ii) Upper Palaeozoic - Britain drifts across the equator. tropical seas [limestone] swamp forest [deltas, coal formation] desert conditions 15oN [wind-formed dune-bedded sandstone, evaporites, breccia] Carboniferous
  9. 9. Upper Palaeozoic (ii) Upper Palaeozoic - Britain drifts across the equator. tropical seas [limestone] swamp forest [deltas, coal formation] desert conditions 15oN [wind-formed dune-bedded sandstone, evaporites, breccia] Permian
  10. 10. Mesozoic Britain at 30o - 40oN; separation of Africa from America extensive warm seas [limestone] Jurassic
  11. 11. Mesozoic Britain at 30o - 40oN; separation of Africa from America extensive warm seas [limestone] Cretaceous
  12. 12. Cenozoic opening of north Atlantic; Britain at 50o - 60oN; diverging plate volcanism in NW Britain; glaciation volcanism (flood basalts) glaciation (glacial till) Tertiary
