Why Sedimentary Geology? Resources Most of the world’s energy supply comes from fossil fuels derived from sedimentary rocks Mineral deposits (e.g., stratabound ores, MVT deposits) Water in aquifers Construction materials
The Hydrocarbon Society In 2001, about 39% of Canada's primary energy production was from natural gas, followed by oil (25%), hydropower (20%), coal (11%), and nuclear power (5%) ~3/4 from sedimentary rocks Oil is the world’s most important energy source (~36% of total consumption)
Why Sedimentary Geology? Employment
Why Sedimentary Geology? Earth and Life History Sedimentary record contains information about past tectonic movements, sea-level change, climates, etc. Sedimentary record hosts the history of life on Earth
Sponge Encrusting algae Marine cement
Capitan Limestone Reef Reconstruction
Why Sedimentary Geology? Environment Sedimentary record contains most of what we know about global change on geologic timeframes Modern sediments can record recent physical/chemical/biological environmental changes Geosphere biosphere interactions Contaminants in aquifers
It was predicted: "When we get the big hurricane and there are 10,000 people dead, the city government's been relocated to the north shore of Lake Ponchartrain, refugee camps have been set up and there $10 billion plus in losses, what then?" Shea Penland, Geologist, Dec. 2000
