Modern geological interest in the caribbean has centered on its cretaceous to recent orogenic belts that resulted from plate interactions between north and south america. The caribbean is the site of america’s most extensive cretaceous and cenozoic oceanic-continental tectonic zone and has (along with the aleutians) its only real island arcs.
The landscape of northern alberta and the underlying mineral formations are the result of millions of years of geologic events. The periodic inundation and retreat of ocean waters over present-day alberta has been one of the most influential processes on alberta’s geology. At the beginning of the paleozoic era (about 600 million years ago), the deposition and decay of the remains of the trilobites, earth’s first skeletal animals, led to the formation of immense layers.
The mesozoic era focuses mostly on the northern basins and the tectonic and tectono-stratigraphic elements. A brief discussion follows on the mesozoic-cenozoic boundary before discussing the tertiary period.

Since the 1960s the advent and acceptance of the concept of plate tectonics has resulted in great interest in detailed reconstruction of the earth's crust and surface in past geological times. Canadian earth scientists are leaders in this work because of the long emphasis on regional geological studies in canada and because of the diversity and complexity of the country - with its enormous precambrian shield core, its widespread interior-platform sediments, its continent-bounding mountain.
Geology geologists break down the earth’s long history into comprehensible intervals of time. The longest intervals — eons — are divided into eras (paleozoic, mesozoic, cenozoic), which are themselves divided into periods such as the quaternary. The periods are further subdivided into epochs, such as the holocene — our own time.

Early adherents including sir charles lyell (1797-1875) advocating the “present is key to the past” concept (uniformitarianism) and william “strata” smith (1769-1839) producing the world’s first nationwide geological map – the “map that changed the world” – were contemporaries of the canadian sir william logan (1798-1875), founder and first director of the geological survey of canada.
