| 摘 要： | 豫西鲁山地区汝阳群发育了形态特征多样的大量微生物成因构造，主要为多边形网格状脱水裂痕和纺锤形脱水裂痕。通过对微生物成因构造宏观特征的描述和统计分析，探讨了微生物成因构造与沉积环境之间的关系，认为微生物成因构造的总体特征演化规律与汝阳群趋于稳定的沉积环境演化一致，其形态特征与微生物席厚、暴露时间频繁有着密切的关系。

| Abstract: | Abundant microbially induced sedimentary structures(MISS) are well preserved in the Ruyang Group in Lushan,western Henan.Two types of the sedimentary structures are identified,including the mesh-shaped and fusular structures.The relationship between the microbially induced sedimentary structures and sedimentary environments indicates that the evolution of the microbially induced sedimentary structures coincides with that of the sedimentary environments in the study area.In addition,there is also close relations between the morphology of the microbially induced sedimentary structures,and the thickness and exposure frequency of the microbial mats. |
