GEOL 716 Lecture 3: Sequence Stratigraphy

2. Sequence Stratigraphy
A framework of genetically related stratigraphic facies geometries and their bounding surfaces used to determine depositional setting

3. Sequence Stratigraphy
Subdivision & interpretation of sedimentary record using a framework surfaces seen in outcrops, well logs, & 2-D and 3-D seismic.
Include:
Surfaces of erosion & non-deposition (sequence boundaries)
Flooding (trangressive surfaces [TS] &/or maximum flooding surfaces [mfs])
This framework used to predict the extent of sedimentary facies geometry, lithologic character, grain size, sorting & reservoir quality
