| English abstract | Lagoa Salgada is located in the northern coast of Rio de Janeiro and is of great scientific relevance for its modern stromatolites. This study aimed to map the types of microbialites, identify damage and threats and provide geoconservation suggestions. Microbialite mapping and sampling was authorized by the administrative body of the Lagoa do Açu State Park - PELAG, where the lagoon is partially located. Petrographic analysis was conducted on stromatolite types according to external morphology. Geology and heritage value data were added to the GEOSSIT platform and analysis of ecosystem services and scientific value was performed based on bibliometrics. Three types of stromatolite were distinguished and mapped (large domal, small domal and branched columnar) with two types of microbial mat (colloform and polygonal). These morphologies suggest different hydrodynamic agents in the growth process and regarding the position in the water column.^ |
