Sedimentary Basin Types Examples

Geologic provinces & common rock types This map shows the distribution of major rock types on the surface of the earth Among the notable aspects of this distribution is the fact that continental cores (shields) are underlain by very old rocks, compared to continental margins, which are typically underlain by young rocks. Note the distribution of volcanoes, and by inference batholiths, around the Pacific Ocean, where oceanic crust is subducting beneath shallower plates.

Geologic provinces & common rock types Rift basins (commonly hidden beneath passive margins) This map shows the distribution of major rock types on the surface of the earth Among the notable aspects of this distribution is the fact that continental cores (shields) are underlain by very old rocks, compared to continental margins, which are typically underlain by young rocks. Note the distribution of volcanoes, and by inference batholiths, around the Pacific Ocean, where oceanic crust is subducting beneath shallower plates.

Passive margin sedimentary basins (Rift basins typically reside beneath Miogeocline, where crust has been thinned)
