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...

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. ...
