O presente trabalho apresenta as principais caracteristicas de cavidades desenvolvidas em quartzitos na regiao sudeste de Diamantina/MG. O procedimento metodologico utilizado consiste em: a) revisao bibliografica; b) trabalhos de campo que incluiram prospeccao e levantamento topografico com grau de precisao BCRA 4C; c) processamento dos dados de campo com a utilizacao dos softwares OnStation e Corel Draw e c) correlacao de projecao horizontal das cavidades desenvolvidas em rochas siliciclasticas na regiao SE de Diamantina e no Brasil. Os resultados obtidos demonstram a presenca de cavidades na regiao SE de Diamantina com projecao horizontal que varia de 9,6m a 593,5m. A maioria das cavidades da area de estudo apresenta morfologia de teto e piso suavemente inclinados, predominantemente concordantes com a direcao de caimento da vertente. Os saloes geralmente possuem morfologias retangulares, triangulares e elipticas horizontais. Palavras-chave : Cavidades em Quartzito, Caracterizacao, Diamantina/MG. Abstract This paper presents the main features of caves developed in quartzite in southeast region of Diamantina/MG. Its methodological procedure consisted of: a) literature review; b) field studies including prospection and topographic survey with a BCRA 4C accuracy degree; c) fieldwork data treating using the softwares  OnStation and  Corel Draw ; and c) correlation of the horizontal projection of the caves developed in siliciclastic rocks in southeast region of Diamantina and in Brazil. The results show the existence of cavities in southeast region of Diamantina with horizontal projection ranging from 9.6 m to 593.5 m. Most caves in this study area present its ceiling and floor morphology gently sloping, mostly concordant with the slope trim direction. The halls typically have rectangular, triangular and elliptical horizontal morphologies. Keywords: Cavities in Quartzite, morphology characterization, Diamantina / MG.
