From: Gravity modeling finds a large magma body in the deep crust below the Gulf of Naples, Italy
Petro-physical and density model of the large scale low-density volume of the area. It summarizes the density and temperature variation vs. depth through the crust/mantle section (left side), and the hypothesized magmatic processes (center). Right side: Variation with depth of volume of molten fraction, cumulates and country rocks. The layered model (Fig. 4) assumes densities based on this parameter variation with depth.
