| 摘 要： | 豫西地区中元古代汝阳群砂岩中普遍发育微生物形成的沉积构造(Microbial Induced Sedimentary Strutures),简称MISS构造,这些MISS构造在过去通常被误认为前寒武纪后生动物遗迹化石。本文对豫西地区中元古代汝阳群MISS构造的形态、结构及显微构造特征进行了详细地分析研究,结果表明该区发育的MISS构造有4种类型:多边形网状裂隙构造、纺锤形裂隙、鸟足形裂隙和典型的正弦曲线型Manchuriophycus构造。豫西地区中元古代汝阳群微生物形成的沉积构造的发现,不仅表明这些砂岩层面上曾经存在微生物席活动,对今后与一些微生物席活动有关的沉积构造的研究有着重要的借鉴意义,为过去被误认为各种遗迹化石的修定提供了证据,而且对恢复前寒武纪沉积古地理具有重要的意义。

| Abstract: | Microbial Induced Sedimentary structures(MISS) in sandstone beds are abundant in the Palaeoproterozoic Ruyang Group,western Henan Province.In the past,the MISS were regarded as the oldest trace fossils of metazoa in Precambrian.This paper has studied the characteristics of MISS's macroscopic morphologies,structures and microfabrics in the Palaeoproterozoic Ruyang Group of western Henan Province.The results suggest that there are four types of MISS,i.e.,'polygonal reticulation cracks','spindle cracks','bird ... |
