| 초록 | Causes of lamination, the most salient property of stromatolitic structures, are examined in terms of sedimentary kinetics and stasis using case histories of modern stromatolite-building biota from the Bahama Carbonate Platform, Great Sippewissett Salt Marsh of New England, and Hamelin Pool, Shark Bay, Australia. The findings are compared with fossil evidence preserved in silicified Mesoproterozoic stromatolites of the Gaoyuzhuang Formation, northern China. Multitrichomous cyanobacteria and their responses to sedimentation characterize the conditions of fluctuating sedimentation rates, whereas coccoid cyanobacteria colonize and stabilize sediments during periods of sedimentary stasis. |
