These data are supplementary material to “Lithospheric 3D gravity modelling using upper-mantle density constraints: Towards a characterization of the crustal configuration in the North Patagonian Massif area, Argentina” (Gómez Dacal et al. 2017).

The North Patagonian Massif (NPM), in central Argentina, includes a plateau of an average altitude of 1200 m.a.s.l. mostly surrounded by basins that stand between 500 to 700 m below it. Geological observations and previous works indicate that the present-day elevation of the plateau was reached in the Paleogene by a sudden uplift that did not involve noticeable deformation. To gain insight into the causes of the uplift and the geodynamic development of the area, it is necessary to characterize the present-day configuration of the lithosphere.
The lithospheric-scale 3D model was developed by integrating all the available data of the area (e.g. regional and global models of different layers, seismic data, xenoliths) to build an initial structural model. Details on the datasets used for each model layer are listed in the main article. Furthermore, the initial model was tested against the gravity observations with the objective of assessing the depth of the crust–mantle discontinuity (Moho). The density model was built with IGMAS+ software (Interactive Geophysical Modelling Assistant, Götze and Schmidt, 2010). During the construction of the initial density model, we tested different mantle density scenarios obtained using P- and S-wave velocities from tomographic models, converting them into densities and comparing the conversions with densities obtained from xenoliths.
