Pangaean aggregation and disaggregation with evidence from global climate belts

Abstract

A study of using climate sensitive deposits as a compiled climatic data to locate global climatic belt boundaries through time is developed by the present authors since the 1990s. Global latitudinal belts were presented from Cambrian to Permian as well as the interval from the early Late Cretaceous to the present. However, during the later Permian and into the Early Cretaceous we noted that the failure of the tropical-subtropical belt to penetrate into the interior of Pangaean resulted in the merging of the two arid belts associated with the northern and southern Hadley Cells into one vast, interior arid region. A Pangaeanic paleogeography dominates and obviously affects the climatic distribution from the Late Permian to Early Cretaceous. We employ the dismission and reoccurrence of the global latitudinal climate belts to determine the aggregation and disaggregation of the Pangaean.
