Petrology of the late-Carboniferous Punta Falcone gabbroic complex, northern Sardinia, Italy

The Punta Falcone gabbroic complex in northern Sardinia, Italy is a parental magma formation that came from the introduction of high-alumina basalt into partially uncrystallized granite magma. The interior and marginal interaction zones in the gabbroic complex feature varied structures due to the low pressure and closed-system crystallization that happened in the interior zone. Cumulus crystals and trapped liquids abound in the chamber, creating different rock protrusions. Chemical and physical processes like crystal fractionation and thermodynamic instability also aid in the structural formation of the gabbroic complex.
