Tectonic Regime Identification
Do one of two things with these lettered locations, either:
» Identify the stage of the Wilson Cycle they formed in, or . . .
» Identify what tectonic regime they represent; e.g. DCM, volcanic arc, axial rift. etc.
Each letter is hot; clicking on it will take you to the stage the tectonic feature first formed in. Sometimes their Formation extends over more than one stage.
