Tethyan Trend
The Tethyan Trend refers to an expansive area of fold belts that range from Western Europe to the Australian coast. Formation of this area began with the separation of Eurasia from Gondwana in post-Paleozoic times, resulting in the creation of the Tethys Ocean. Subsequent convergence and collision of the Africa and Eurasia tectonic plates, which began at the start of the Late Cretaceous, caused subsequent uplift and folding. Additional plate convergences of the Philippine, Pacific and Australia plates caused additional deformation in this area (De Graciansky et al., 2011).
