摘　　要：FIAS tool has been used extensively by for more than a decade to unravel the deformational puzzle.Orogenic processes have always challenged scientists,as rocks usually reactivate during the repeated cycles of deformation and consequently the evidences in the matrix are misleading.This paper presents results obtained fiom Rockies in Colorado USA.A succession of four FIAS as observed in porphyroblasts that could not have been preserved if they had rotated during the
