Geological calendar.
Geological principles state that if a fragment of rock is included, that is entirely surrounded by rock, it must be older than the surrounding rock. This is because it had to be present for the rock to form around it.

Earth’s tilt and the sun’s alignment over the equator determine both the solstices and equinoxes. The equinoxes mark the times when the sun passes directly above the equator. Cenozoic Era.

Information about future and past GSA events, including GSA Connects, Section meetings, and special events.How long is the geologic calendar? Earth’s age is approximately 4.5 billion years so that’s why we use billions, millions, and thousands of years as time markers. Typically, we use abbreviations like ‘Ga’ (giga-annum), ‘Ma’ (mega-annum), and ‘Ka’ (kilo-annum). For example, 2.5 Ga refers to 2.5 billion years ago.

The present-day state of play is reviewed, both in the refinement of the geological calendar and the finesse that has been attained.
The geologic calendar is not as neat as the astronomical calendar, but it has the same purpose of organizing time into recognizable units. (See Image 1.) There are four Eras. Each Era is characterized by geological changes brought about by water, wind, earthquakes, or volcanoes and by the development of plant and animal life.
