We present a robust compilation (1120 data in almost 30 years of research) of fission-track and (U-Th)/He studies and their implications to the understanding of Brazilian geomorphology development. Brazil has a complex geological evolution, involving multiple orogenic and taphrogenic episodes that shaped cratons, orogens, and basins together through time. The thermochronology data set is inconsistently distributed, most of it is concentrated in coastal regions, mainly in the southeastern region; while the intracontinental portions lack studies. The available data set suggests a complex reactivation scenario near the coast to a more stable situation inland. The Mantiqueira and Borborema provinces show a great Early Cretaceous denudation event and a less important Permian to Jurassic, and Paleogene denudation events. The cratonic areas show different patterns, with denudation related to the Devonian to the Jurassic. The data suggest that elastic thickness, structural network, and drainage system play an important role in the morphotectonic control of Brazilian landscape evolution.A termocronologia de baixa temperatura se concentra na compreensão da história térmica da crosta superior, onde ocorrem os processos morfotectônicos. Apresentamos uma compilação robusta (1120 dados em quase 30 anos de pesquisa) de estudos de rastros de fissão e (U-Th)/He e suas implicações para a compreensão do desenvolvimento da geomorfologia brasileira. O Brasil tem uma evolução geológica complexa, envolvendo múltiplos episódios orogênicos e tafrogênicos que formaram crátons, orógenos e bacias juntos ao longo do tempo. O conjunto de dados de termocronologia é distribuído de forma inconsistente, a maior parte concentrada nas regiões litorâneas, principalmente na região sudeste; enquanto as porções intracontinentais carecem de estudos. O conjunto de dados disponíveis sugere um cenário de reativação complexo perto da costa para uma situação mais estável no interior. As províncias da Mantiqueira e da Borborema apresentam um grande evento de desnudamento do Cretáceo Inferior e eventos menos importantes de desnudamento do Permiano ao Jurássico e do Paleógeno. As áreas cratônicas apresentam padrões diferenciados, com denudação relacionada ao Devoniano ao Jurássico. Os dados sugerem que a espessura elástica, a rede estrutural e o sistema de drenagem desempenham um papel importante no controle morfotectônico da evolução da paisagem brasileira.engUniversidade Federal de Minas GeraisUFMGBrasilIGC - DEPARTAMENTO DE GEOLOGIAJournal of the geological survey of BrazilAtribuição 3.0 Portugalhttp://creativecommons.org/licenses/by/3.0/pt/info:eu-repo/semantics/openAccessGeocronologiaRochas - Propriedades termicasThermochronologyThermochronometryApatiteFission-track(U-Th)/HeThe state of the art of low-temperature thermochronology in BrazilO estado da arte da termocronologia de baixa temperatura no Brasilinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://jgsb.cprm.gov.br/index.php/journal/article/view/158Tiago Amâncio NovoTobias Maia Rabelo Fonte-BoaJúlia Mattioli RolimAna Carolina Fonsecaapplication/pdfreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGORIGINALThe state of the art of Low-temperature Thermochronology in Brazil.pdfThe state of the art of Low-temperature Thermochronology in Brazil.pdfapplication/pdf3869395https://repositorio.ufmg.br/bitstream/1843/52340/1/The%20state%20of%20the%20art%20of%20Low-temperature%20Thermochronology%20in%20Brazil.pdf19317762cc5a8cfad7807b99024f2315MD51CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml; charset=utf-8914https://repositorio.ufmg.br/bitstream/1843/52340/2/license_rdff9944a358a0c32770bd9bed185bb5395MD52LICENSElicense.txtlicense.txttext/plain; charset=utf-82118https://repositorio.ufmg.br/bitstream/1843/52340/3/license.txtcda590c95a0b51b4d15f60c9642ca272MD531843/523402023-04-20 18:12:14.594oai:repositorio.ufmg.br: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ório InstitucionalPUBhttps://repositorio.ufmg.br/oaiopendoar:2023-04-20T21:12:14Repositório Institucional da UFMG - Universidade Federal de Minas Gerais (UFMG)false
