[en] The calc-alkaline typology of the Moncoutant and Le Tallud quartz-diorites, confirmed by new major and trace element data, and the zircon U-Pb ages obtained on Le Tallud pluton show that these intrusions represent the NW extension of the ''Limousin Tonalitic Line''
[en] New geological, structural and geochemical data show the presence of at least four magmatic units in the Neuvy-Bouin massif. U/Pb zircon age (340±4 Ma) obtained on the Largeasse granites indicates that in the Neuvy-Bouin pluton the magmatic activity began during Visean times. The emplacement of the Largeasse granites is followed by the aluminopotassic two-mica granites of Pougne-Herisson and by two mica leucogranites. The small high-K calc-alkaline granite body discovered in the Neuvy-Bouin pluton represents the first occurrence of this type of magmatism in the area
