Abstarct: We investigate the geometric properties for Hilbert C*-modular frxames‎. ‎We show that any dual frxame pair in a Hilbert C*-module is an orthogonal compression of a Riesz basis and its canonical dual for some larger Hilbert C*-module‎. ‎This generalizes the Hilbert space dual frxame‎ pair dilation theory due to Casazza‎, ‎Han and Larson to dual Hilbert C*-modular frxame pairs‎. ‎Additionally‎, ‎for any Hilbert C*-modular dual frxame pair induced by a group of unitary operators‎, ‎we show that there is a dilated dual pair which inherits the same group structure‎. ‎Finaly we investigate the structure of g-frxames on Hilbert spaces‎.
