摘要

在埃及西奈半岛中西部阿布泽奈玛地区马图拉地层深灰色至黑色页岩面记录到 18 种浮游有孔虫和 11 种底栖有孔虫。该动物群主要由世界性的白鳍类、边缘鳍藻类、双鳍藻类、康图鳍藻类和异形鳍藻类组成。具有高度分类多样性的浮游物种被用来划分康尼阿克纪和山东安纪,以及界定康尼阿克纪/山东安纪的边界,而底栖有孔虫在年龄划分中的作用较小。通过对这些动物的关系和分布范围进行地层分析,确定了五个生物区;Dicarinella primitiva 或 Huberella huberi 或 Marginotruncana sinuosa 代表康尼阿克纪,Dicarinella concavata 和 Dicarinella asymetrica 代表山顿纪。此外,考虑到 Dicarinella concavata 的出现和 Huberella huberi 的消失,以及 Marginotruncanids(M. renzi、M. sigali、M. marginata、M. pseudolinneiana.... 等)的增加,划分了康尼阿世/山顿纪的边界。此外,在马图拉地层中段发现的黑色页岩被认为是科尼阿克-山口洋缺氧事件(OAE3)造成的。在属于五大洲的几个国家中出现的带有浮游有孔虫的黑色页岩,是使这一事件成为全球性事件的主要推动力。

A New Epistemological Insight of the Coniacian-Santonian Oceanic Anoxic Event (OAE3)
Eighteen planktic and eleven benthic foraminiferal species were recorded from the dark grey to black shale facies of the Matulla Formation in Abu Zeneima area, West-Central Sinai, Egypt. The faunal assemblage is dominated by cosmopolitan whiteinellids, marginotruncanids, Dicarinellids, Contusotruncanids and Heterohelicids. The planktic species with high taxonomic diversity were used to zone the Coniacian and Santonian stages, as well as define the Coniacian/ Santonian boundary, while benthic foraminifera is of minor contribution in age assignment. The stratigraphic analysis of the relations and ranges of these fauna led to the recognition of five biozones; Dicarinella primitiva or Huberella huberi or Marginotruncana sinuosa for the Coniacian, while Dicarinella concavata and Dicarinella asymetrica for the Santonian. Also, the Coniacian/Santonian boundary was delineated, considering the appearance of Dicarinella concavata and disappearance of Huberella huberi, as well as the increase of Marginotruncanids (M. renzi, M. sigali, M. marginata, M. pseudolinneiana….etc.). Furthermore, the black shales found in the middle part of the Matulla Formation were attributed to the Coniacian-Santonian Oceanic Anoxic Event (OAE3). The occurrence of black shales with planktic foraminifera during the Coniacian–Santonian interval in several countries belonging to five continents, was the main impetus to render this event a global event.
