Current tufa deposition is evident by up to 1.5 mm thick crusts that have formed on substrate plates placed in the creek for 10 months. Hydrochemistry data indicate that carbonate precipitation along the creek is physicochemically driven by CO2 degassing, whereas photosynthetic carbon assimilation is without detectable effect on the macroscale carbonate equilibrium. However, stable isotope data indicate a minor photosynthetic effect, but only for the lower creek section where the pCO2 already drops to the two-fold of the atmospheric level. Though the initial process of external nucleation on cyanobacterial sheaths in the lower creck section might be promoted of by a photosynthetically-induced microscale pH gradient, the effect is not strong enough to cause a CaCO3 impregnation of the sheaths. The fabric of the laminated tufa crusts in the creek reflects the temporal alternation of porous microspariticPhormidium incrustatum-Phormidium foveolarum-diatom biofilms in spring, micrite-impregnatedPhormidium incrustatum-Phormidium foveolarum-diatom biofilms in summerautumn, and detritus-rich non-calcified diatom-biofilms in winter. By contrast, exopolymer-poor surfaces of cascade tufa mosses show large, euhedral spar crystals. Non-phototrophic bacteria, which occur in large numbers inPhormidium incrustatum-Phormidium foveolarums-diatom-communities, thrive on extracellular polymeric substances (EPS) and dead cells of the cyanobacteria and are unlikely to promote CaCO3 precipitation."],["dc.identifier.doi","10.1007/BF02668163"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/15163"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.relation.eissn","0172-9179"],["dc.relation.eissn","1612-4820"],["dc.title","Fluvival tufa formation in a hard-water creek (Deinschwanger Bach, Franconian Alb, Germany)"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dspace.entity.type","Publication"]]
