During the realizing process of the Project “Geological mapping and mineral resource investigation at 1:50.000 of the Tánh Linh map sheet group”, for the first time the project  authors discovered mafic magmatic blocks of gabbro, norite gabbro at the Núi Đan Mt area, Hàm Thuận Nam District, Bình Thuận Province. Through the study on geological, petromineral and petrogeochemical materials, they have been recognizing the difference between the Núi Đan mafic magmatic formation and divided ones in South Trung Bộ and it has close relation to granitoids of the Late Cretaceous Ankroet Complex. On the basis of collected factual materials, the project authors have been establishing a new magmatic complex - the Núi Đan one.
