| 摘 要： | 豫西云梦山组发育了大量的微生物成因沉积构造（MISS）。在地层纵剖面上,毫米级的深色沉积物层和浅色的石英颗粒层交替出现,形成典型的微生物席纹层,代表着微生物席在沉积表面的多次生长和埋藏。深色层包含有泥质物和细砂-粉砂颗粒,被认为是先前微生物席的残留区;浅色层则是较纯净的石英颗粒,由物理沉积作用形成。进一步对纹层区的薄片...

| Abstract: | The Precambrian biosphere includes almost exclusively microbiota.Activities of benthic prokaryotes in response to the sedimentary dynamics could form the characteristic structures known as Microbially Induced Sedimentary Structures(MISS),arising syndepositionally from the interactions of biofilms and microbial mats with the sedimentary grains due to the variations in hydraulic parameters in siliciclastic aquatic environments.Yunmengshan Formation,belonging to Mesoproterozoic Ruyang Group,lies in the south m... |
