Petrogenesis and tectonic significance of Late Jurassic–Early Cretaceous volcanic-intrusive complex in the Tianhuashan basin, South China

The Late Mesozoic geological framework of South China is characterized by voluminous volcanic rocks and their intrusive counterparts. However, the ages, petrogenesis, and tectonic implications of the Late Mesozoic magmatism in South China, especially those in the Qinhang zone, are poorly constrained. The Tianhuashan basin is one of the important volcanic basins along the southern margin of the Qinhang zone, and is mainly composed of the Daguding...
