Exempel på hur du använder CHRON i en mening

• On November 29, 2018, the journal Science announced the dating of the site by four corroborating methods: negative geomagnetic polarity reported to the Matuyama chron, ESR dating, biochronology (fossil species assemblages) and sedimentation rate.
• Recent magnetostratigraphic dating demonstrates that the Cozy Dell at its type locality was deposited during the chron 20 geomagnetic reversal through the chron 19 reversal - approximately 46 to 42 Ma (million years ago), which is consistent with deposition during Lutetian time.
• The correlation of the magnetization pattern of the ridge and the geomagnetic polarity timescale suggests that the volcanism that created the ridge started ~80 Ma (magnetic chron time 33r) in the Mahanadi Basin and the process continued southwards, ending at ~55 Ma near the Afanasy Nikitin Seamount.
