Permian Permian The Permian is a geologic period and system which spans 47 million years from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic period 251.902 Mya. It is the last period of the Paleozoic era; the following Triassic period belongs to the Mesozoic era. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the city of Perm. The Permian witnessed the diversification of the early amniotes into the ancestral groups of the mammals, turtles, lepidosaurs, and archosaurs. The world at the time was
Carabobo Field attributed to the formation of the field is when North America separated from Gondwanaland in the Late Triassic/Early Jurassic (~200 million years ago). The rifting in this period is represented by Late Jurassic basalts deposited in the Espino graben. This event led to the northern passive margin of South America. During the Cretaceous Period (~150 million years ago), the passive margin began to subside from organic rich sediments being deposited. This deposition includes the Querecual and San Antonio formations that would become source rocks for the Orinoco Oil Belt. The next tectonic event is referred to as a progressive collision
