I will talk about some preliminary elements of an ongoing work on f(R,T)theories of gravity in metric-affine spaces. I will show that these theories can be handled in a similar way as standard metric-affine f(R) theories and, with more generality, any Ricci-based theory of gravity. I will also discuss briefly the conservation equation, the Newtonian limit, and some potential applications of these theories.
