摘要: We present an integrated geomagnetic polarity and stratigraphic time scale for the Triassic, Jurassic, Cretaceous periods of Mesozoic Era, with age estimates uncertainty limits stage boundaries. The uses a suite 324 radiomenc dates, including high-resolution 40 Ar/ 39 Ar estimates. This framework involves observed ties between (1) radiometric biozones, boundaries, (2) biozones magnetic reversals on seafloor in sediments. Interpolation techniques include maximum likelihood estimation, smoothing cubic spline fitting, magnetochronology
