DYNAMICS OF CLASTIC SEDIMENTS IN CAVE: POTENTIALITY FOR PALEO-ENVIRONMENTAL STUDY IN BRAZIL

Abstract

aleoenvironmental records are important for understanding the current processes of landscape evolution. The cave environment are protected from the superfi cial evolution having excellent sedimentary records, sometimes analogous to the surface. In this way, clastic sediments are a good source of paleoenvironmental study, being almost unexplored in Brazil. This paper presents a review of sediment records in cave environments, discussing aspects such as alteration, classifi cation, sedimentation processes, diagonal and facies, with the methods used for paleoenvironmental records (Carbon 14, luminescence, statistics and chemical techniques). The potential of this goal in Brazil whas showed by the search for recent articles available on the CAPES portal, based on Web of Science. The topyc is still incipient in view of the number of caves mapped. Results show a timid, but signifi cant increase in research in the last decade. The good response to the use of the proxies covering intervals up to million years is an alternative for Brazilian paleoenvironmental studies given the diffi culty of fi nding such dynamics in a tropical surface environment.
