1 Sedimentary Geology Introduction

2 Professor Bruce Hart Earth and Planetary Sciences, FDA 332, Telephone: Office Hours: By appointment

3 T.A.s Tim McCullagh Dirk Schumann

4 Time Classes: Monday and Wednesday, 11:30am-12:30pm, FDA Laboratories: Wednesday, 2:30- 5:30pm, FDA N.B. Two field trips will be held during term, requiring extended time periods on these days (to be discussed in class).

5 Grading 30 % laboratory exercises/field reports 10 % term projects/presentations 0-20 % mid-term examination % final examination

6 Academic Integrity McGill University values academic integrity. Therefore all students must understand the meaning and consequences of cheating, plagiarism and other academic offences under the Code of Student Conduct and Disciplinary Procedures (see for more information).

9 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

10

11 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)

12 Why Sedimentary Geology? Employment

13 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

14

15 Sponge Encrusting algae Marine cement

16 Capitan Limestone Reef Reconstruction

18 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

22 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
