The Phu Khanh Basin is located in the southwestern part of the South China Sea and is a part of the central and southern Vietnamese continental margin, which marks the transition zone between the con-tinental Indochina block and the South China Sea (Figure 1). The basin occupies much of the continental margin off central Vietnam and it is long and wide, extending north to south by approximately 350 km and its width is up to 200 km. It is bounded to the west by a narrow shelf, separated from the Song Hong Basin to the north by the Da Nang Shear Zone and from the Cuu Long Basin to the south by the Tua Hoa Shear Zone (Canh et al., 1994).
