对北海中部英国板块在560n至580n之间的第四纪地层进行了修订（图1），揭示了比以前已知的更完整的更新世沉积物序列。建立了区域地震地层格架，并对钻孔资料进行了古地磁和微体古生物学分析，确定了下更新世至全新世的沉积物年龄。这与先前的研究结果相反，先前的研究表明，第四纪演替的大部分是上更新世（中至上魏希塞利世）时代。Kurzfassung。英国北部中部地区第4季地层修正-参见zwischen 560 N和58 0 N (siehe Abb. 1)，第1季度沉积纪（dedie第四纪沉积纪）。因此，我们研究了一种新方法，即沉积与更新世（mittleres bis oberes weichsel - glazal）的关系。地震学、地震学、地震学、地震学、地震学、地震学、地震学、地震学、地震学、地震学、地震学等。英国地质调查局（BGS）最初在1969年至1975年期间对北海中部进行了调查，并建立了初步的、非正式的第四纪地层（HOLMES 1977, THOMSON & EDEN 1977）。然而，作为英国大陆架区域1:25万比例测绘计划的一部分，BGS在1980/81年获得了地球物理和地质数据，有必要对地层序列进行重新评估。通过结合新旧资料，完成了对早期地层及其非正式命名法的修订（STOKER等）。)，我们在此提供该研究的摘要。修订后的地层演替见图2，新旧地层术语见表1。新的命名法采用“形成”作为主要的局部单位。然而，由于地层层序是建立在早期工作的基础上的，因此，已有的地质特征是：作者地址：Dr. M.

A revision of the Quaternary stratigraphy in the UK sector of the central North Sea between 560 N and 58 0 N (Fig. 1) has revealed a more complete sequence of Pleistocene sediments than was previously known. A regional seismostratigraphic framework has been established, and palaeomagnetic and micropalaeontological analysis of borehole data has identified sediments ranging from Lower Pleistocene to Holocene in age. This contrasts with earlier studies which suggested that the bulk of the Quaternary succession was of Upper Pleistocene (Middle to Upper Weichselian) age. Kurzfassung. Wie eine quartiirstratigraphische Revision im britischen Sektor der zentralen Nord see zwischen 560 N und 58 0 N (siehe Abb. 1) ergab, ist die quartiire Sedimentabfolge wesentlich umfangreicher, als bisher angenommen wurde. So sind bislang die quartiiren Sedimente nur dem hochsten Pleistoziin (mittleres bis oberes Weichsel-Glazial) zugeordnet worden. Auswertungen seismischer Messungen sowie paliiomagnetische und mikropaliionotologische Analysen fiihrten da gegen zum Nachweis von Sedimenten des tiefen Pleistoziins bis Holoziins. Introduction The central North Sea was initially surveyed by the British Geological Survey (BGS) during the period from 1969 to 1975 and a preliminary, informal Quaternary strati graphy was erected (HOLMES 1977, THOMSON & EDEN 1977), However, the acquisition of geophysical and geological data in 1980/81 by the BGS, as part of their regional off shore 1 :250,000 scale mapping programme of the UK continental shelf, has necessitated a reappraisal of the stratigraphic sequence. By combining the old and new data a revision of the earlier stratigraphy and its informal nomenclature has been completed (STOKER et a!., in press), and we present here a summary of that study. The revised stratigraphic succession is illustrated in Fig. 2 and the old and new stratigraphic terminology is presented in Table 1. The new nomenclature adopts the 'formation' as the primary local unit. As the stratigraphic sequence is based on earlier work, however, pre-existing geo':. Authors' address: Dr. M. S. STOKER, D.
