What is basin analysis?

What is basin analysis?

• Geologic method
• Defining and describing a sedimentary basin
• Analyze the sediment
• Composition
• Primary structures
• Internal architecture

• Describe basin components
• Backarc
• Forearc
• passive margin
• Epicontinental
• Extensional

5
Controls of basins

• Sediment supply (uplift of source area)
• Subsidence (thrusting, flexing of the
  lithosphere)regional tectonic activity
• Sea level (climate)
• The rates of these processes is more important
  then their magnitude.
