Geochemical features of the Neoproterozoic igneous rocks from the Wudang region and their implications for the reconstruction of the Jinning tectonic evolution along the south Qinling orogenic belt.;

Wudang area in Hubei province is an important metallogenic zone with excellent ore-forming background.
