Abstract

The claystones of Jaguariúna (SP) have been studied in their taphofloristic composition (after their morphology and taxonomy) and some palaeoclimatic and paleoecological inferences are been extracted from it. The morphographic and taxonomic features of the phytofossils and of the lithology suggest a wet tropical climate, in the area, in the lifetime of the paleoflora and its deposition, characterized by a wet tropical forest, different of the semidecidual wide leaf tropical forest, living until recently on that area. By other hand, mineralogical analysis of the kaolinite of the matrix rock have been made, by X-ray Diffraction and SEM, leading to the same inferences on climatical conditions dominants in the deposition site.
