We investigate transfer of nonclassical correlations through one-dimensional quantum networks for several schemes by employing concurrence and local quantum uncertainty as the measures and the extended Werner-like states as the initial resources. The exact dynamics of quantum correlations are derived, and the differences of dynamics between concurrence and local quantum uncertainty are analyzed. Besides, the influences of node number and initial parameters on the generation of quantum correlations between the two end nodes are discussed. Moreover, we explore the effects of duplex encodings and double channels on distribution of quantum correlations.
