| Abstract: | Haoxi Nb-Ta mineral deposits in Guangning County of Guangdong Province occurs in the C- formation of Sinian system strata and the folding structures and faulted structures is a very development in the area. The pegmatite Nb-Ta mineral veins were controlled by a group of horizontal tenso-shear axial-direction fault-fissure systems in the NNE direction folding structures. The faulted structures play double role of controlling and destroying ore-formation. In order to find new pegmatite Nb-Ta ore-deposit, it is very important practical-significances to ascertain the host structure characteristics and the relations between the tectonic epochs and ore-forming. |
