摘  要:一、前言“千尼尔”(chenier)一词源于法文“Ie Chene”,系指被栎树覆盖的意思。“千尼尔”沙岗(海沼沙岭)是位于海岸沼泽平原中的弧立沙脊或介壳碎屑脊,在地层中称谓“千尼尔”砂岩体。“千尼尔”沙岗及其与之相关的滨岸沼泽平原构成“千尼尔”平原。笔者对华北地区南部多条石炭系本溪组(C<sub>2</sub>b)至二叠系山西组(P<sub>1</sub><sup>1</sup>s)完整剖面的剖析及区域资料研究表明,太原组(C<sub>3</sub>t)沉积时期滨海平原发育有“千尼尔”沙岗。The interbedded sediments of the deep-water clastic rocks and clear-water carbonate rocks in the Upper Carboniferous Taiyuan Formation in southern North China are interpreted as the alternating marine and continental sediments which are formed in strand plain, gulf, barrier lagoon and epi-continental shallow marine environments. The“cheniers”developed on the strand plain during the deposition of the Taiyuan Formation owe their origin to frequent storm processes in the light of vertical sequence analysis and associated regional data. Their formation has revealed the complex history of transgression-regression related to sea level rises and falls, and has constructive implications for coal accumulation and subsequent hydrocarbon accumulation and preservation in the peat bogs on the strand plain.
