The rheology of the lithosphere
The mechanical behaviour, or rheology of the lithosphere. Sedimentary basins are regions of long-term subsidence of, in most cases, […]
Interpreting ancient environments
Defining the lithosphere
Sedimentary basins are lithosphere-scale structures. They occupy the uppermost levels of tectonic plates, responding to deep-seated processes generated at plate
Sedimentary basins: Regions of prolonged subsidence
An introduction to the dynamics of Sedimentary basins. I don’t know about you, but at an outcrop I tend to
Which sequence stratigraphic model is that?
Assessing different sequence stratigraphic models. The concept of unconformity-bound sequences was first proposed by Sloss et al. (1949, Sloss (1963)
Depositional systems and systems tracts
Depositional systems and systems tracts are central to the construction of sequence stratigraphic profiles. Stand back and observe an active,
Stratigraphic condensation – condensed sections
Condensed sections record multifarious interactions of physical, biological, and geochemical processes played out over long time spans, all condensed into
Stratigraphic lapout geometry
This post about lapouts (onlap, toplap, downlap, offlap, truncation) is a companion to Clinoforms and clinothems An important part
Clinoforms and clinothems
Earth’s surface is a time plane. It is a plane of deposition and erosion, of chemical precipitation and dissolution, domicile to countless
Stratigraphic trends and stacking patterns
Stratigraphic trends in outcrop and core, and the role they play in identifying parasequence stacking patterns. Recognition of stratigraphic trends,
Shorelines and shoreline trajectories
A brief look at identifying shoreline trajectories in stratigraphic successions. This post is part of the How To…series on Stratigraphy
