    Abstract:

    Qishan ilmenite deposit in Juxian County is the first evaluated largescale ilmenite deposit. It is located tectonically in the Gongdanshan uplift of the middle part of the Yishu fault belt. The primary rock and orebodies are brownish green, finegrained titaniumbearing magnetiteamphibole pyroxene. Among the five bodies discovered, the No. I, II and III ore bodies were controlled in project. The No. 1 orebody is 1600 m long, with an average of 180 m, a controlled depth of 204 m, and the average TiO2 and TFe grades of 8.68% and 18.46%, respectively. The No. II orebody is 880 m long, with an average width of 160 m, a controlled depth of 120 m, the average TiO2 and TFe grades of 8.33% and 17.07%, respectively. The No. III orebody is 1600 m long, with a width of 25 ~ 67 m, a control depth of 170m, the average TiO2 and TFe grades of 8.86% and 20.13%, respectively. The orebody coefficient varying from 7.06% to 42.0% suggests the orebodies with stable grade. This deposit is characterized by large scale, simple form and easytoexploitation. Based on study on its geological characteristics, it is proposed that this deposit belongs to magma differentiated ilmenite deposit at early period, which formed in the Paleoproterozoic era.
