Comparativo study of six granitoid complexes associated with transcurrent faults in the State of São Paulo, Brazil, concerning their architecture and magmatic cycles is presented. Three of these complexes are calc-alkaline (Itaqui, São Roque, Cantareira) and the other three are rapakivi ones (São Francisco, Sorocaba, Itu). The architecture of the complexes is the result of the coalition of severa! magmatic phases with the following temporal emplacement sequence: 1. Early Phase; 2. Main Phase; 3. Early Lateral Accretionary Phase; 4. Phase of Stocks and Circular Intrusions; 5. Final Lateral Accretionary Phase. Also the magmatic units whiçh built up the complexes belong to at least two magmatic cycles with or without an intra-cycle mafic dike phase. The recurrence of the architecture style and the presence of successive magmatic cycles in ali complexes independently of their serial character is discussed in terms of magma emplacement mechanisms, the presence of collecting magma chambers successively tapped and recharged and the reactivation-phases of the transcurrent faults to which the complexes are associated.

ZusammenfassungDie Puna NW-Argentiniens ist strukturell in ein pal~iozoisches Grundgebirge und ein jungmesozoisch-k~inozoisches Deckgebirge gegliedert. Das Deekgebirge ist besonders dureh junge Bruchtektonik gepr~igt und wurde vom mittleren Terti~ir his in das Quartiir von versehiedenen Vulkaniten durchsetzt.Diese Vulkanite lassen sich in zwei Gruppen einteilen: Eine stratigraphiseh ~iltere Generation besteht aus typischen Kalkalkali-Serien, wie sic auch in den benachbarten Andenabschnitten vorkommen. Dagegen zeigen die jfingsten Vnlkanite eine Verwandtschaft zu Alkali-Serien und dfirften aus dem oberen Mantel stammen. Es sind Heine, isolierte Vorkommen, die an jungo Bruehstrukturen gebunden sin& Auf den Zusammenhang zwischen diesen kontinentalbasalt4ihnlichen Gesteinen und der quasi-kratonisehen Struktur der Puna wird hingewiesen. AbstractThe Puna of NW-Argentina is divided into a Paleozoie basement complex and a late Mesozoic-Cenozoic sedimentary cover. The sedimentary cover was affected by late fracture tectonics and, from middle Tertiary to Quaternary times, invaded by various volcanics.These volcanics can he subdivided into two groups. A stratigraphically older group of volcanic rocks which belongs to the typical ealc-alkaline rock series that is also found in the adjacent parts of the Andes.A younger group of volcanics which is similar to the alkaline rock series and possibly of upper mantle origin. The rocks of this group form small isolated occurrenecs connected to late fracture zones.Comments are made on the relations between these continental basalt-like rocks and the quasi-cratonie structure of the Puna.
