O artigo contém revisão bibliográfica sobre origem e ambiente de formação dos arenitos de praia, assunto hoje em discussão no meio científico. Com base em diversos autores, busca-se apresentar os ambientes de formação e respectivos processos de gênese, tanto físico-químicos quanto por atividade microbiana destacando os processos de cimentação e seu papel enquanto indicadores de antigos níveis marinhos.

Environments of Formation, Processes of Cementation of Beachrocks and Indicators of Sea Level Variations
ABSTRACT
This paper contains a literature review on the origin and environment of formation of beachrocks, a very relevant topic of discussion within the scientific community. Based on various authors, we seek to present the environments of formation and their genesis processes, both physical-chemical and by microbial activity, highlighting on the cementing processes and their role as indicators of older sea levels.
Keyswords: Beachrocks, diagenesis, cementation, sea level.
