项目摘要

This study has its aims to establish chronostratigraphy and international correlation of the Cretaceous deposits in the north Pacific regions as well as to consider the establishment of the north Pacific bioprovince from analysis of yielded macro faunas. For this purpose, international field expedition has been carried out in 2002-2004 for the marine Cretaceous deposits on the U.S.Pacific coast. The marine Cretaceous deposits (Great Valley Sequence) widely exposed along the Sacramento Valley, northern California and those in the Talkeetna Mountains, southern Alaska have been studied from the lithostratigraphic, biostratigraphic and magnetostratigraphic points of view. As a result of our field and laboratory studies successively collected fossil samples and sediment core samples, detailed mega-and microfossil biostratigraphic frameworks have been established for the Barremian to Turonian sequence in the North Fork Cottonwood Creek, northern California. Also, five magnetostratigraphic stages, i.e., M5,M3,M1,M0r,C34n (with M-1r reversal horizon) were recognized in the Barremian to Lower Albian sequence. This is the first report of the high-resolution Early to Middle Cretaceous biochronology and magnetostraligraphy in the North pacific regions. We have also recognized the continuous highly fossiliferous marine Campanian to Maastrichtiain strata from the Talkeetna Mountains, southern Alaska.

本研究旨在建立北太平洋地区白垩纪沉积物的年代地层学和国际对比，并从已获得的大型动物群分析中考虑北太平洋生物省的建立。为此，我们于2002-2004年对美国太平洋沿岸白垩纪海相沉积物进行了国际实地考察。本文从岩石地层学、生物地层学和磁地层学的角度，对广泛暴露于加利福尼亚北部萨克拉门托山谷和阿拉斯加南部塔尔基特纳山脉的海相白垩纪（大峡谷层序）矿床进行了研究。通过野外和实验室研究，先后收集了化石样品和沉积物岩心样品，建立了北加州北福克Cottonwood Creek地区Barremian - Turonian层序的大、微化石生物地层格架。在巴雷米亚—下阿尔贝统层序中，识别出M5、M3、M1、M0r、C34n 5个磁地层阶段（具有M-1r反转层位）。这是北太平洋地区早白垩世至中白垩世高分辨率生物年代学和磁地层学的首次报道。我们还认识到阿拉斯加南部塔尔基特纳山脉的连续的高化石海洋坎帕尼亚至马斯特里赫特地层。
