Within the context of prospecting operations of pegmatite bodies hosted in granites in the Ponte da Barca region, we sought to detect lithologic interfaces from which the relationship between the spatial and structural organization of the outcropping pegma‐ tite bodies could be established, by combining field work and remotely sensed data analysis. The evidence of curvilinear alignments in LANDSAT imagery, especially well ‐marked in the images obtained from the application of classification algorithms, are compatible with the 1 Sinergeo, Lda – Edifício IEMinho, Lugar de Casal, 4730 -575, Soutelo, VILA VERDE; geral@sinergeo.pt 2 DCT, Universidade do Minho – Campus de Gualtar, 4710 -057, BRAGA; caal.gomes@gmail.com 3 GGC, Lda Rua Cunha Jr., 41 B s 1.6, 4250 -186, PORTO, jhc@ggconsult.com.pt 236 existence of concentric planar or plan ‐linear fluidalities, possibly inherited from ballooning plumes. We thus verified a spatial correlation between the pegmatite outcrops and ballooning plumes peripheries, which separate different domains of phenocristaline clustering.
