Introduction

• Definitions
• Sedimentology the study of the processes of
  formation, transport and deposition of material
  which accumulates as sediment in continental and
  marine environments and eventually forms
  sedimentary rocks
• Stratigraphy the study of rocks to determine
  the order and timing of events in Earth history
• Sedimentary geology ? sedimentology
  stratigraphy
• Sequence stratigraphy the analysis of
  genetically related depositional units bounded by
  unconformities and their correlative conformities

8
Introduction

• Historical development of sedimentary geology and
  key concepts
• Principle of superposition (Nicolas Steno, 1669)
• Uniformitarianism (the present is the key to the
  past) (James Hutton and Charles Lyell, late 18th
  to early 19th century)
• Stratigraphy developed already around 1800
• Sedimentology is a relatively new discipline
  (1960s and 1970s)
• Late 1980s and 1990s revival of stratigraphy
  (sequence stratigraphy)

9
Introduction

• Temporal and spatial scales
• Sedimentology focuses primarily on facies and
  depositional environments (how were
  sediments/sedimentary rocks formed?)
• Smaller temporal and spatial scales
• Stratigraphy focuses on the larger scale strata
  and Earth history (when and where were
  sediments/sedimentary rocks formed?)
• Larger temporal and spatial scales
