Stratigraphic correlation date range

Fossil assemblages were traditionally used to designate the duration of periods. Since a large change in fauna was required to make early stratigraphers create a new period, most of the periods we recognize today are terminated by a major extinction event or faunal turnover. A stage is a major subdivision of strata, each systematically following the othe… Web11 Apr 2024 · A broad age population range between ∼3600-3450 Ma, recorded in the detrital zircon spectra of the metapelite sample CB11C and micaceous quartzite sample CH5B (Figs. 5 b and d, Supplementary data table S2a), is also encountered in both quartzite (CA34) and calc-silicate gneiss (CG2L and C46) samples of the Sukma Group …
