Patrimônio geológico e mineiro no nordeste do Brasil

Abstract

The Brazilian Northeast has a unique geological diversity and is part of the national geological heritage. This region, in terms of minerals, rocks, fossils, landscapes (relief), and other elements of geodiversity, presents examples of the most instructive and comprehensive, ranging from ancient rocks of the crystalline basement (> 3 billion years) until the coverage dunes (<5000 years) and recent sediments in their beds of rivers, lakes and lagoons. Many of these examples are potential monuments, which are now awakening, as well as scientific interest-didactic, too touristic, historical and cultural.At themomentwe have all 164 geosites, scattered in different bases, constituting 14 thematic categories, with emphasis on sedimentology, paleontology and geomorphology. There are countless examples of geologicalmining heritage identified but it should be remembered that these are only a small sample of what the Northeast has. Better understand this heritage and protecting it is importance, given that it has the particularity of being unique and irretrievable: once decayed is lost forever!
