Dividing Earth History into Time Intervals. Geologists have divided Earth's history into a series of time intervals. These time intervals are not equal in length like the hours in a day. Instead the time intervals are variable in length. This is because geologic time is divided using significant events in the history of the Earth. Humans subdivide time into useable units such as our calendar year, months, weeks, and days; geologists also subdivide time. They have created a tool for measuring geologic time, breaking it into useable, understandable segments. For the purposes of geology, the “calendar” is the geologic time scale. Geologic column and its associated time scale. The end product of correlation is a mental abstraction called the geologic column. It is the result of integrating all the world’s individual rock sequences into a single sequence. In order to communicate the fine structure of this so-called column, it has been subdivided into smaller units. The geologic time scale is a system used by scientists to describe Earth's history in terms of major geological or paleontological events (such as the formation of a new rock layer or the appearance or demise of certain lifeforms). Geologic time spans are divided into units and subunits, the largest of which are eons. This 2012 geologic time scale is an enhanced, improved and expanded version of the GTS2004, including chapters on planetary scales, the Cryogenian-Ediacaran periods/systems, a prehistory scale of human development, a survey of sequence stratigraphy, and an extensive compilation of stable-isotope chemostratigraphy. gsa geologic time scale v. 5.0 cenozoic age epoch age picks magnetic polarity period hist. chro n. quater-nary pleistocene* miocene oligocene eocene paleocene pliocene piacenzian zanclean messinian tortonian serravallian langhian burdigalian aquitanian chattian rupelian priabonian bartonian lutetian ypresian danian thanetian selandian calabrian
