Magmatism in the Asunción-Sapucai-Villarrica Graben (Eastern Paraguay) Revisited: Petrological, Geophysical, Geochemical, and Geodynamic Inferences

Figure 9

Earthquakes distribution at the Paraguay and neighbouring regions: open and full circles, earthquake hypocenters >500 and <70 km, respectively [29]. Heavy black lines indicate extensional lineaments: PGA, Ponta Grossa Arch; PAR and PYL, Paraguays and Pylcomaio lineaments, respectively (cf. also inset of Figure 3). The dark grey delineates the rotational subplate trends [24, 95]. ASV: Asunción-Sapucai-Villarrica graben.
