AB Direct evidences or magmatic convective flow in granitic pluton are scarce. The possible complex historyof magma cooling in pluton can delele partially or completely this registration. We describe a complexelliptical structure in a porphyritic monzogranite and the granitic fabric around this. We distinguish threezones based on the study of their morphology and internal Structures (cross-cutting layering, curvedschlierens, lobulated mafic-leucocratic laminate). We propose a model of verticall flow pipes with motionor magma generation point. Three possible convective build  the elliptical structure. This model issimilar those proposed in the literature for snail and ladder dike structures. Fabric defined by K-feldsparsmegacryst in the inmediatelly surrounding is basically linear to 355·010º
