Study Notes
Formation of Hydrocarbons Lecture Key Points
- New lithosphere is created at mid-ocean ridges where seafloor spreading occurs
- The subsurface carbon cycle involves organic matter burial and remobilisation as oil and gas
- Many source rocks for oil correspond to the age of mass extinction
- The lecture covers fossil fuels, carbon capture & storage, and plate tectonics
- The primary focus of the carbon cycle is the cycling of carbon between the atmosphere, the oceans, and rocks
- Old lithosphere returns to the asthenosphere at subduction zones
- The surficial carbon cycle involves the transfer of carbon between soil, vegetation, the oceans, and the atmosphere
- The downstream process in hydrocarbon production involves refining
- The upstream process in hydrocarbon production involves exploration and production
- Source rock maturation is crucial for the development of hydrocarbons within a petroleum system
- The East Orphan Basin is known for its significant petroleum potential, particularly in sedimentary rocks
- Basalt is primarily produced at seafloor spreading centers
