Wilson Cycle

The processes is driven by Plate TectonicsA simple explanation of the Wilson cycle includes two phases the Opening phase and a Closing phase explained below in Stage A to F figure 1.

Wilson cycle. A Wilson cycle describes a large tectonic cycle lasting for more than 100 million years. The Wilson Cycle explains the process of the opening beginning and the closing end of an ocean. Life cycle of ocean basins - Wilson 1968 Stage Dominant motions Characteristic features Typical igneous rocks Typical sediments Metamorphism Examples 1.

My pre-1968 experience disposed me to try to play a part in testing these ideas. The Wilson cycle begins in Stage A with a stable continental craton. This process not only splits a continent in two it also creates a new divergent plate boundary.

Tuzo Wilson who first described it in 1966 and it outlines the ongoing origin and breakup of supercontinents such as Pangea and Rodinia Scientists have determined this cycle has been operating for at least three billion years and possibly earlier. Wegener theorized that all the continents as they are today were once joined in single large landmass PangeaThe Wilson cycle named after J. One of the first to recognise how plate tectonics could be applied to the geological record was J.

The oldest seafloor material found today dates to only 170 million years old whereas the oldest continental crust material found today dates to 4 billion years showing the.

Plate tectonics is one of the great unifying theories in geology. If you love bikes and love sharing your passion for riding with others have experience working in a bicycle retailer and have outstanding customer service skills then Wilsons may be the place for you. A Wilson cycle describes a large tectonic cycle lasting for more than 100 million years.

The Wilson Cycle is named for J. As the crust continues to thin due to extensional tectonic forces an ocean basin forms and sediments accumulate along its margins. Tuzo Wilson had identified three basic elements of geodynamics.
