The Geologic Time Scale. The geologic time scale. Image by Jonathan R. Hendricks for the Earth@Home project. Note that the geologic time scale above is not scaled to time and mostly represents the Phanerozoic Eon. Mosts of geologic history (88%) happened during the Precambrian, which is represented by Hadean, Archean, and Proterozoic eons.based on lithology or on the geologic time of deposition. The three types of units. Time Units (eon, era, period, epoch, age) are names given to sections of the geologic time scale. The time scale was originally developed by putting formations observed in Western Europe in order from oldest to youngest and by dividing them into groups basedDaylight saving time was first observed in the United States in 1918. It was introduced as a way to make better use of daylight and reduce energy. The beginning and end dates of daylight saving time vary from country to country.

Relative dating is used to arrange geological events, and the rocks they leave behind, in a sequence. The method of reading the order is called stratigraphy (layers of rock are called strata). Relative dating does not provide actual numerical dates for the rocks.Figure 2. Principle of cross-cutting relationships (units numbered in order from oldest to youngest; Southwick and Lusardi, 1997, fig. 2). Magnetostratigraphy is a technique for dating sedimentary and volcanic rocks that uses information on the remanent magnetization within the rock, which correlates to the polarity of the Earth's magnetic field at the time the rock formed.Scientific.

A. Nature of Chronostratigraphic Units. Chronostratigraphic units are bodies of rocks, layered or unlayered, that are defined between specified stratigraphic horizons which represent specified intervals of geologic time. The units of geologic time during which chronostratigraphic units were formed are called geochronologic units.Geologic Time Scale.
