In this note we introduce the notion of the relative symplectic cone CMV. As an application, we determine the symplectic cone CM of certain T2-fibrations. In particular, for some elliptic surfaces we verify the conjecture in [17]: If M underlies a minimal Kähler surface with pg > 0, the symplectic cone CM is equal to Pc1(M) ∪ P-c(M), where Pα = {e ∈ H2(M;R)|e·e > 0 and e·α > 0} for nonzero α ∈ H2(M;R) and P0 = {e ∈ H2(M;R)|e·e > 0}.
