In the framework of three light Majorana neutrinos, we show how to reconstruct, through the use of 3x3 unitarity, the full PMNS matrix from six independent Majorana-type phases. In particular, we express the strength of Dirac-type CP violation in terms of these Majorana-type phases by writing the area of the unitarity triangles in terms of these phases. We also study how these six Majorana phases appear in CP-odd weak-basis invariants as well as in leptonic asymmetries relevant for flavored leptogenesis.
