Microbial mats in coastal environmentstidal sediments (Cohen et al. 1984; Cohen and Rosenberg 1989). A noticeable similarity of these environments is their relative low species diversity. Particularly, multicellular organisms are excluded from such environments and it has been conceived that the absence or limited activity of grazing or

Microbial mats in a thermomineral sulfurous cave (Feru and Capotà 1991). Hydrogeologieal studies performed during the last 60 years (Macovei 1912; Ciocîrdel and Protopopescu-Pache 1955; Moissiu 1968; Feru and Capotà 1991) identified a deep captive sulfurous aquifer located in Barremian-Jurassic limestones, extending 15 km to the North and 50 km t

The laminated structure of these vertically stratified benthic ecosystems is the result of the development of the constituent microflora along physical and chemical gradients. Thus, i

Biological versus inorganic processes in stromatolite morphogenesis: Observations from mineralizing tion. In general, all sedimentary laminations reflect periodic interruptions in deposition. For example, in stromatolites formed in detrital sedimentary systems, laminations may arise through variations in current velocity and rates of sedimentation (Farmer and Des Marais 1993). In mineralizing sedi
