Faults – some common terminology
A fault is a plane or linear zone of displacement, where rocks on one side of the plane slip past […]

Stereographic projection of linear measurements
Stereographic plotting of linear structures and measurements. Geologists are interested in the orientations of rock and mineral structures. We spend
Nascent conjugate, passive margins
Progression of continental rifting to sea floor spreading creates paired (conjugate) passive margins over which post-rift successions accumulate across crust
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)
