2. 1. Overview Cenozoic Quaternary (Pleistocene and Holocene) Neogene Palaeogene 0 Ma 1.6 Ma 23 Ma 65 Ma Mass extinction Temperature falls Growth of North Atlantic, Himalayas, Alps.

3. 2. Global tectonics + India collides with Asia further East.

4. 3. British Geology Erosional limit of Cenozoic sediments UK Lavas Igneous centres Isolated basins

5. 4. North Atlantic Region Iceland Hotspot LIP active 60-58 Ma 1 2 3 Moine Thrust Great Glen Fault Highland Boundary Fault Skye Rhum Ardnamurchan Mull Arran Northern Ireland Igneous centres exhumed through erosion. Lavas above are gone, preserved further West.

6. 5. North Sea Deltas Regional crustal extension affects N. Sea. Up to 3 km extension, with extensive basin formation. Local uplift in Highlands supplies sediment. Large deltas form. Central Graben UK Oil fields: Forties, Ekofisk, Montrose Deep sea muds Turbidites

7. 6. Southern England Records local deformation of Alpine Front. eg. Isle of Wight monocline. Also records deposition in isolated basins, sometimes terrestrial, sometimes connected to North Sea or Atlantic.. Variations in character of sedimentation related to eustatic sea level change. London Platform Alpine Front London Basin Weald Basin London Clay Bagshot Beds Sea level rise

8. 7. Ice Devensian Ice limit Anglian Ice limit Main Loch Lomond Ice Ice forms in Antarctica - 38 Ma Ice in Atlantic - 3 Ma Glaciation in UK - 600 000 Ya Loch Lomond readvance - 15 000 - 10 000 Ya Modern coastline and topography dominated by ice effects.
