abstract = {Let \( M \) be a family of Mumford-type, that is, a family of polarized complex abelian fourfolds as introduced by Mumford in [9]. This family is defined starting from a quaternion algebra \( A \) over a real cubic number field and imposing a condition to the corestriction of such \( A \). In this paper, under some extra conditions on the algebra \( A \), we make this condition explicit and in this way we are able to describe the polarization and the complex structures of the fibers. Then, we look at the non simple \( CM \)-fibers and we give a method to construct a family of Mumford-type starting from such a fiber.},
