We tested and analyzed the major elements��rare earth elements and carbon and oxygen isotopic of the wall rock alteration in the Hu-Bi copper deposit of Shanxi Zhongtiao mountains�� Major element feature shows that host rocks are rich in Si and Al��but poor in K; siliceous albitite is obviously rich in Na; marble is poor in Na�� REE characteristics show that the ΣREE value in host rocks is very low generally��relatively enriched in light REE��and characteristic in negative Eu anomaly��not obvious in Ce anomaly��LaN /YbN = 1. 70 �� 5. 21��LaN /SmN = 0. 85 �� 3. 8��and GdN /YbN = 0. 72 �� 3. 26�� Carbon and oxygen isotopic research indicates that δ13 CPDB concentrats in �� 4. 3 × 10 �� 3 �� �� 0. 2 × 10 �� 3 between marine carbonate rocks ( 0) and igneous rocks ( �� 5 × 10 �� 3 �� �� 8 × 10 �� 3 ) ��δ18 OPDB concentrats in �� 13 × 10 �� 3 �� �� 18 × 10 �� 3 �� The study suggests that the Hu-Bi copper deposit has the features of the exhalative sedimentary deposit because there are many similarities between the Hu-Bi copper deposit and other typical exhalative sedimentary deposits in geochemistry�� Carbon and oxygen isotopic research shows that C in ore-forming fluids coming from the mantle and marine carbonate rock ( seawater) may have magmatic C added��
