PIZANI Ciencias de la Tierra zeolites cyanobacteria Biostabilization microbial activity Bahía Blanca Estuary The influence of microbial activity in carbonatic environments leading to stromatolitebuild-ups is widely known. In siliciclastic environments, however, this influence has been far lessstudied. The present study was carried out in this type of environment and determined theimportance of cyanobacterias in the preservation of sedimentary structures. Similar sedimentarystructures were also recognized in the rock record by other studies. Therefore, if we know theenvironment of formation and conservation of such structures, then the paleoenvironment of therock could be inferred.In the tidal flats of the Bahía Blanca Estuary, microbial mats were identified. Their interaction withsediments, lead to a stabilized flat by shielding from erosion the existing sedimentary structures.Since it is the first time these structures are mentioned in a present-day environment in Argentina,a detailed description of the bio-sedimentological interaction is presented and our results comparedwith others from different climatic zones, namely, temperate humid and subtropical arid. Finallythe occurrence of zeolites, an authigenic mineral, indicated that the sediment would be in the earlystages of diagenesis. 2007 artículo científico 1851-4979 https://www.redalyc.org/articulo.oa?id=381740360002 en http://www.redalyc.org/revista.oa?id=3817 Latin American Journal of Sedimentology and Basin Analysis application/pdf Asociación Argentina de Sedimentología Latin American Journal of Sedimentology and Basin Analysis (Argentina) Num.2 Vol.14 |
