| Abstract: | Dongjiankou and Zhashui masses are located in the southern boundary of Shangdan junc-tion belt between north Qinling and south Qinling tectonic belts, which are products of vol-canic activity in the process of Shangdan junction belt subduction and collision duringVariscan-Indosinian. Ring-mottled granite supply the chemical geological composition andevolutional history for the Shangdan junction belt. |

| Keywords: | Dongjiankou ultra-unit Zhashui ultra-unit ring-mottled geological characteristic |
