  1. Geologic Calendar (Geology ⛰️)

    The Geologic Calendar is a scale in which the geological timespan of the Earth is mapped onto a calendrical year; that is to say, the day one of the Earth took place on a geologic January 1 at precisely midnight, and today's date and time is December 31 at midnight. On this calendar, the inferred appearance of the first living sing...

  6. Stage (stratigraphy) (Geology terminology ⛰️)

    In chronostratigraphy, a stage is a succession of rock strata laid down in a single age on the geologic timescale, which usually represents millions of years of deposition. A given stage of rock and the corresponding age of time will by convention have the same name, and the same boundaries. Rock series are divided...

  8. Kyr (Geology ⛰️)

    The abbreviation kyr means "thousand years". kyr was formerly common in some English language works, especially in geology and astronomy, for the unit of 1,000 years or millennium. The "k" is the unit prefix for kilo- or thousand with the suffix "yr" simply an abbreviation for "year". Occasionally, the "k" is shown in upper case, as in "100 Kyr"; this is an incorrect usage. "kyr" itself is often considered incorr...

  9. Chronozone (Geology terminology ⛰️)

    A chronozone or chron is a unit in chronostratigraphy, defined by events such as geomagnetic reversals, or based on the presence of specific fossils. According to the International Commission on Stratigraphy, the term "chronozone" refers to the rocks formed during a particular time period, while "chron" refers to that time period. ...

  11. Myr (Geology ⛰️)

    Mya is an abbreviation for million years ago, a unit of time equal to 1,000,000 years, or 31.556926 teraseconds. It is equivalent to one megaannum, based on the metric prefix mega-.
