The analysis of the direction of fluidalities marked by potassium feldspar megacrystals and supermicaceous enclaves (biotitic and, occasionally, with some tourmaline) is a criterion that helps in understanding the way in which plutonites are placed. In the case of this Natural Monument, the fluidalities and enclaves observed here have sub-horizontal or even horizontal trajectories, this fact coincides with the installation model of the Plutonite of Bouça de Frade.
