Their petrogra-phic and geochemical characteristics are similar to monsogabbro and monsodiorite, while the age dating (SHRIMP from zircon in monzogabbro, 250.4 ±2 Ma, coeval to Nui Chua massive 251 ±3 Ma).<br />The modeling of Nui Chua massive‘s forming process shows that Son Dau massive and its satellite at the western part of Nui Chua massive were generated from residual high alkalic magmatic liquids by fractional crystallization. The forming conditions are 750-840 °C and 2-3 kbar. In addition, this area has large ore deposit potential, because of high titanomagnetite and ilmenite content in monsogabbro and monsodiorite.</p>}, number={1}, journal={Vietnam Journal of Earth Sciences}, author={Hùng, Trần Quốc and Poliyakov, G.V. and Shelepaev, P.A. and Hòa, Trần Trọng and Phượng, Ngô Thị and Balykin, P.A. and Izokh, A.E. and Niên, Bùi Ấn and Sukhorukov, P.V.}, year={2012}, month={Jun.}, pages={8–17} }
