Allochthonous terranes – suspect and exotic
Allochthonous terranes, suspect terranes, exotic terranes. In 1972 James Helwig introduced the concept of orogenic collage, wherein orogenic belts were
Basins formed by strike-slip tectonics
By the early 1970s, the new tectonics (the plate kind) had established a firm grip on the geological consciousness. Even

Accretionary prisms and forearc basins
Forearc basins are kinematically linked to accretionary prisms. Forearc basins and accretionary prisms are located in the arc-trench gap
Thrust faults: Some common terminology
Some terminology for Thrust faults, duplexes, imbricate fans, and fold-thrust belts. Thrusts are reverse faults having fault plane dips <45o,
Basins formed by lithospheric flexure
Basins formed by flexure of oceanic and continental lithosphere; foreland basin exemplars. What is flexure? The way we define the
Faults – some common terminology
A fault is a plane or linear zone of displacement, where rocks on one side of the plane slip past
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
