In the context of FDM on a structured grid, is the discretization of differential operators for multiblock meshes the same as curvilinear meshes?

For curvilinear meshes we introduce x = x(\xi,\eta). With this in hand for d/dx (in 2D):

\frac{\partial}{\partial x} = \frac{1}{J} \left[\frac{\partial}{\partial \xi} \frac{\partial y}{\partial \eta} - \frac{\partial}{\partial \eta} \frac{\partial y}{\partial \xi}\right]

My question is whether or not I can apply the same type of methodology when solving my problem on a multiblock mesh. Apologies for my ignorance!
