The northeast portion of the Parana Sedimentary Ba‑ sin is distinguished by structural highs as the known Pitanga Dome, an uplifted structure identified in the last century. It represents a ge‑ ological and evolutionary evidence of the Parana Sedimentary Basin and has undergone inspired studies and intense exploration surveys. This study consists of a gravimetric survey in the Pitanga Dome area, State of Sao Paulo, Brazil. The Bouguer gravity anomalies have been identified and related to the structural high, sedimentary thickness, and the basement morphology. Processing and enhancement tech‑ niques were used for forward modeling based on previous studies. The  three models from profiles sectioning the dome have a sedi‑ mentary thickness varying from 200 to 1.250 meters. The adopted methodology has provided important results determining that the Pitanga Dome can be understood through rational 3D visualization. The area can be interpreted as an undulating basement with thinning of sedimentary rocks related to deep features (structures) in the crust/ mantle limit (Moho uplift). This characteristic is confirmed by the sedimentary layer thickening present throughout the surrounding area. The results also offer important insights and support for further studies concerning the genesis and evolution of this and other uplif‑ ted structures of the Parana Sedimentary Basin.
