Chronology


Definition:

  • (n.) The science which treats of measuring time by regular divisions or periods, and which assigns to events or transactions their proper dates.

  • (20) His instinct that there was something there in the association beyond simple chronology is rewarded in the details.

Stratigraphy


Definition:

  • (n.) That branch of geology which treats of the arrangement and succession of strata.

Example Sentences:

  • (1) People are environmentally aware these days but maybe the information is not available to them to show the scale of changes that are happening.” The international team behind the paper includes several other members of the Subcommission on Quaternary Stratigraphy’s Anthropocene working group, which hopes to present a proposal to the ICS later this year.
