Bowring, Samuel A.; Williams, Ian S. Priscoan (4.00–4.03 Ga) orthogneisses from northwestern Canada. Contributions to Mineralogy and Petrology. 1999, 134 (1): 3. Bibcode:1999CoMP..134....3B. doi:10.1007/s004100050465. The oldest rock on Earth is the Acasta Gneiss（英语：Acasta Gneiss）, and it dates to 4.03 Ga, located in the Northwest Territories of Canada.

上石炭紀地質在歐美及中國均以盛產煤炭著名，因此便以石炭紀為此時代地層的名稱，但在美國則以密士西必紀作為下石炭紀，另以賓夕法尼亞紀稱上部石炭紀。[1]

Historically, the 新生代 has been divided up into the 第四紀 and 第三紀 sub-eras, as well as the 新近纪 and 古近纪 periods. The 2009 version of the ICS time chart recognizes a slightly extended Quaternary as well as the Paleogene and a truncated Neogene, the Tertiary having been demoted to informal status.

Paleontologists often refer to faunal stage（英语：faunal stage）s rather than geologic (geological) periods. The stage nomenclature is quite complex. For an excellent time-ordered list of faunal stages, see The Paleobiology Database. [2006-03-19].

Dates are slightly uncertain with differences of a few percent between various sources being common. This is largely due to uncertainties in radiometric dating and the problem that deposits suitable for radiometric dating seldom occur exactly at the places in the geologic column where they would be most useful. The dates and errors quoted above are according to the International Commission on Stratigraphy 2004 time scale. Dates labeled with a * indicate boundaries where a Global Boundary Stratotype Section and Point has been internationally agreed upon: see Global Boundary Stratotype Section and Points - International Commission on Stratigraphy，存于互联网档案馆 for a complete list.

在北美，石炭纪被细分为 Mississippian（英语：Mississippian） and Pennsylvanian（英语：Pennsylvanian） Periods.
Defined by absolute age (Global Standard Stratigraphic Age（英语：Global Standard Stratigraphic Age）).
Though commonly used, the Hadean 不是一个正式的 eon 并且没有商定太古宙和太古宙的下界。 Hadean 有时也被称为 Priscoan 或 Azoic。有时，可以发现冥古界是根据 lunar geologic time scale. These eras include the Cryptic and Basin Groups (which are subdivisions of the Pre-Nectarian era), Nectarian, and Early Imbrian（英语：Early Imbrian） units.
