At the 75th Annual Meeting of the North American Commission on Stratigraphic Nomenclature, 22 October, 2020, in connection with GSA 2020 Connects Online, the Commission voted unanimously to accept the revision of Articles 73, 81 and 82 of the North American Stratigraphic Code (North American Commission on Stratigraphic Nomenclature, 2005 with subsequent updates), and concomitant changes to Table 2; specific revisions of the Code are indicated in red color. These replace all older versions of the specified Articles. An application for this revision (Aubry et al. 2019) was published in Stratigraphy more than one year prior to the meeting; thus, the vote on this application for revision follows Article 21 of the Code.
在2020年10月22日举行的第75届北美地层命名委员会年会上，与GSA 2020在线连接有关，委员会一致投票通过了对《北美地层学法典》第73条、第81条和第82条的修订(北美地层命名委员会，2005年及其后续更新)，以及对表2的相应修改;本守则的具体修订以红色标示。这些替换指定条款的所有旧版本。这次修订的申请(Aubry et al. 2019)在会议召开一年多前发表在《地层学》上;因此，对这一修订申请的表决遵循《治罪法》第21条。

ABSTRACT: A new sequence stratigraphic framework for Turonian to Santonian (94-84 Ma) sediments is established using data from the USGS Kure Beach and Elizabethtown cores collected from the Atlantic Coastal Plain of North Carolina (NC). These sediments represent some of the oldest marine units deposited on the southeastern Atlantic Coastal Plain and record the early development of a clastic wedge atop crystalline basement. Sediments were deposited as transitional marginal-marine to marine units in a complex interplay of fluvial, estuarine, and shelf environments. Repetitive lithologies and minimal biostratigraphic control requires an integrated analysis of grain-size data, geophysical logs, biostratigraphy, and 87Sr/86Sr isotopic data to identify systems tracts and establish a sequence stratigraphic framework. From this integrated approach, three Turonian to Santonian sequences in the Elizabethtown core and six in the Kure Beach core are identified. The new sequences from oldest to youngest are Clubhouse II, Fort Fisher I, Fort Fisher II, Collins Creek I, Collins Creek II, Pleasant Creek I, and Pleasant Creek II. Sequences from North Carolina document significant shifts of global and regional sea-level during greenhouse conditions in the early Late Cretaceous. Maximum sea-level rise occurred globally during the early Turonian and is documented from the marine sediments of the Clubhouse II sequence. This sequence is unconformably overlain by terrestrial sediments deposited during a major fall in sea level and maximum progradation of the shoreline, as evidenced by the Fort Fisher I sequence. Global sea-level rise in the Coniacian resulted in the deposition of the Fort Fisher II sequence, which is present only in the Kure Beach core. Local marine circulation and erosion on the shelf is suggested by the absence of the Collins Creek I sequence at Kure Beach; this sequence is present only in the up-dip Elizabethtown core. Activation of a possible buried fault structure along the Cape Fear arch resulted in the formation of a regional depocenter during the late Coniacian to early Santonian and is reflected in the unusual thickness of the Collins Creek II and Pleasant Creek I sequences. The return to a more global sea-level influence occurred in the late Santonian with the deposition of the Pleasant Creek II sequence. A comparison of temporal distribution of sequences in the Elizabethtown and Kure Beach cores to corresponding sequences in New Jersey indicates significant differences in erosional and tectonic processes in the Cape Fear region during the Turonian and Santonian.
摘要:利用美国地质调查局(USGS)在美国北卡罗来纳州大西洋沿岸平原(NC)的Kure Beach和Elizabethtown岩心数据，建立了一个新的Turonian - sanantonian (94-84 Ma)沉积层序地层格架。这些沉积物代表了大西洋沿岸平原东南部最古老的海洋单元，记录了结晶基底上碎屑楔的早期发育。沉积物是在河流、河口和陆架环境的复杂相互作用下作为过渡的边缘海洋到海洋单元沉积的。重复的岩性和最小的生物地层学控制需要对粒度数据、地球物理测井、生物地层学和87Sr/86Sr同位素数据进行综合分析，以识别系统域并建立层序地层格架。通过这种综合方法，确定了伊丽莎白镇岩心的3个Turonian - sanantonian层序和Kure Beach岩心的6个层序。新序列从老到小依次为Clubhouse II、Fort Fisher I、Fort Fisher II、Collins Creek I、Collins Creek II、Pleasant Creek I和Pleasant Creek II。北卡罗莱纳的序列记录了晚白垩纪早期温室条件下全球和区域海平面的显著变化。全球最大海平面上升发生在早Turonian，并从Clubhouse II序列的海洋沉积物中记录。该层序由海平面大幅下降和海岸线最大进积期间沉积的陆相沉积物不整合覆盖，如Fort Fisher I层序所证明的那样。Coniacian的全球海平面上升导致了Fort Fisher II层序的沉积，这种层序只存在于Kure Beach岩心中。Kure Beach的Collins Creek I序列的缺失表明大陆架上的局部海洋环流和侵蚀;这种层序只存在于伊丽莎白镇上倾的岩心中。在Coniacian晚期至Santonian早期，沿Cape Fear拱可能隐伏的断裂构造被激活，形成了一个区域性沉积中心，这反映在Collins Creek II和Pleasant Creek I层序的异常厚度上。随着普莱森特溪II层序的沉积，全球海平面影响的回归发生在晚三东世。Elizabethtown和Kure Beach岩心层序与新泽西州相应层序的时间分布对比表明，在Turonian和sanantonian期间，Cape Fear地区的侵蚀和构造过程存在显著差异。
