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?

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

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

Why Sedimentary Geology?

Hazards/Engineering Sediment transport/erosion affect

engineering works (e.g., harbours, navigation routes)

Sediment transport/erosion affect structural stability

Sediment texture (e.g., grain size) affects mechanical properties

Slope instability

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?"
