polymetallic metallogenic belt. Many geological explorations have been carried out by Hunan Geological Prospecting Units in this region. And Qibaoshan, Jingchong copper-polymetallic deposit, Huangjindong gold deposit, Longwangpai tungsten and molybdenum polymetallic ore deposit have been found and identified. Moreover, these ore deposits received great attentions and profound studies(LIU Gouqun et al,1999,2000;HU Xiangzhao.2000;WU Guangying et al,2001;JIA Dacheng et al.2002;FU Gonggu et al,2002;Xiao Yongjun et al,2002,2004;MAO Jingwen et al,2004;HE Zhuanli et al,2004), The main achievement is that the close relationship between Yanshanian granites and ore deposits has been proved. However, previous works mainly focused on surface or within 300m of underground. In the recent years, the geological prospecting in this region, especially in the deep prospecting, has little progress due to various reasons. Changchong ore deposits of Liuyang city, located in the southern part of prospecting area of the northeast Hunan. The strata are mainly Lengjiaxi ultramarine gray, graygreen medium-thick-bedded metamorphic sandstone, fine sandstone and silty slate(TANG Xiaoshan,1989). There are 28 granodiorite porphyry dykes, with length of 100 300m, width of 0.55.0m, which generally toward the north FU Gonggu, CHEN Bihe, TAN Shimin and ZHENG Zhengfu, 2014.
