Foram reconhecidos diversos tipos de fragmentos juvenis na matriz das brechas de facies diatrema, incluindo armoured lapilli, frozen droplets e spinning droplets. Este trabalho descreve os spinning droplets e propoe um modelo para sua gerafao em diatremas. Palavras-chave: spinning droplets, kamafugito, diatrema, lapilli ABSTRACT Kamafugitic lavas, dykes and diatremes occur in the Aguas Emendadas Region, southern Goias, forming part of the Late-Cretaceous Rio Verde-Ipora Igneous Province. A variety of lapilli-sized juvenile fragments occurring in the matrix of diatreme-facies breccias were recognised. These include armoured lapilli, frozen droplets and spinning droplets. This work describes the spinning droplets and proposes a model for their formation in diatrene environments.
