【 摘 要 】

The coastal plains consist of extremely dynamic environments that contain sedimentary packages of relevance for the coastal studies. These sedimentary packages denote characteristics of the transport agents and the deposition environments, being these characteristics of fundamental importance for the knowledge of the local geological history. Therefore, the objective of this work is to characterize, through the textural analysis, the Quaternary sediments and depositional environments of the coastal plain that represents the depositional lagoon-barrier IV system in the lagoons of Esteves, Faxinal and Mãe Luzia, southern Santa Catarina, Brazil. The study polygon consists of a barrier area and a retro barrier area. The barrier area consists of sandy sediments from eolic and shallow marine environments, and the back barrier area by sand and mud sediments of lagoon environments.
