        • An Update on Tourmaline from Luc Yen, Vietnam

          A few pegmatites throughout Luc Yen were found to contain gem-quality tourmaline, and the Minh Tien pegmatite formed 30.58 Ma (Nhung et al., 2007; Huong et al., 2016). Thus, gem-quality tourmaline-bearing pegmatites do not relate to Paleozoic and Triassic magmatic activities in this region but appeared simultaneously with the displacement
