| 摘 要： | 本文通过大比例尺野外测量及镜下观察，对鲁西寒武系第三统张夏组的附枝菌与附枝菌微生物灰岩特征进行了详细研究。附枝菌是一种树枝状蓝细菌，一般向上生长扩展，形成灌木状附枝菌群落，生长于附枝菌微生物丘内部。而在微生物丘的外部边缘，附枝菌群落呈半闭合的房室状，与肾状菌十分相似。房室状附枝菌群落可能是在微生物丘外部边缘受局部高能微环境（如水流、波浪等）的影响形成的。在其形成后，其保存状态则是由附枝菌的钙化作用及早期成岩作用决定。由于附枝菌构成其微生物岩的生长骨架，且该微生物岩不具备清晰的中型构造，故可称其为附枝菌格架岩，作为对微生物岩分类命名的又一补充。附枝菌格架岩一般生长于台地边缘或台地外部斜坡环境，其生长过程受水动力条件、阳光照射及海水清澈度等影响。 |

| Abstract: | This paper studied in detail the characteristics of Epiphyton and Epiphyton microbialites in the Zhangxia Formation(Third Series of Cambrian),Shandong Province.Epiphyton is dendritic cyanobacteria,which usually grow upward to form bush-like colonies in the interior of the microbial mounds.Chambered Epiphyton colonies,similar to Renalsis in terms of morphology,were found in the outer part of the microbial mounds.Chambered Epiphyton colonies formed due to local high-energy conditions(e.g.,currents or waves) i... |
| Keywords: | Epiphyton chambered framestone Zhangxia Formation Third Series of Cambrian West Shandong |
