Stretching the lithosphere; Rift basins
Rift basins, ocean basins, and passive margins form a dynamic continuum within the framework of plate tectonics. This post looks […]
Interpreting ancient environments
Classification of sedimentary basins
The rationale for classification of sedimentary basins The formulation of plate tectonic theory in the late 1960s led to a
The thermal structure of the lithosphere
The thermal structure of the lithosphere influences its strength and rheology, and the diagenetic-metamorphic changes in sedimentary basins. Temperature is
Isostasy: A lithospheric balancing act
Isostasy describes the state of balance between the lithosphere and asthenosphere. Isostasy describes the state of gravitational equilibrium in the
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,
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
