| 摘 要： | 黄骅坳陷古近系沙河街组的生物灰岩发育于沙一段下部的"特殊岩性段"内,其分布具有北区零星、中区集中、南区广泛的特点。沙一段生物灰岩在坳陷北区仅在板桥地区的唐家河一带零星见到;在中区主要见于港西凸起和孔店凸起之间,沿着大中旺-周清庄-王徐庄-扣村一带分布;在南区则分布广泛,主要有4个发育带:沧州发育带、舍女寺发育带、盐山发育带和集北头-灯明寺发育带。综合分析认为,沙一段生物灰岩分布的控制因素主要有古气候、古水体介质条件、古水深、古地形坡度以及陆源碎屑的供给等。 |

| Abstract: | The biogenic limestones are developed in the lower ＂special lithologic part＂ of the first member of the Palaeogene Shahejie Formation in the Huanghua depression.They are scattered only in the Tangjiahe area in the northern part;concentrated in the Dazhongwang-Zhouqingzhuang-Wangxuzhuang-Koucun zone between Gangxi uplift and Kongdian uplift in the central part,and wide-spread in Cangzhou,Shenusi,Yanshan and Jibeitou-Dengmingsi regions in the southern part.The controlling factors of the distribution of the biogenic limestones in the study area include palaeoclimates,fossil water depth and medium conditions,slope gradient of palaeotopography and supply of terrigenous clastics. |
