Abstract： For a Calabi--Yau threefold (CY3), it is known that the movable cone is covered by the nef cones of all its birational minimal models. This arrangement is called the movable fan. We study the movable fan of certain CY3s in projective bundles which admits a determinantal contraction to a CY3s with only ordinary double points. Our construction unifies certain examples in literature. This is joint work with Ching-Jui Lai.
