The Fankou deposit is hosted by carbonate rocks of Devonian, the Guitou group in Lower Devonian (D1-2gt) mainly developed quartz sandstone with purple and gray, the color of it changed from purple and gray throught hyrothermal alteration to gray-white; the Dong gangling group in Middle Devonian (D2d) mainly developed shale, dolomite, the stripes of limestone, it was the transitional layer between the lower of sandstone to the upper of carboninte, and one of the ore-bearings stratigraphy; oolite limestone, dark-grey of the nodular limestone, argillaceous limestone, dolomitic limestone and dolimite developed in the Tian ziling group in Upper Devonian (D3t), it was the majorest stratigraphy, hyrothermal solution case the dolomitization; the Mao zifeng group in Upper Devonian (D3m) mainly developed dark shale and siltstone; the Meng Gongao (C1m) and Ce shuizu group (C1c)in lower Carboniferous developed marlstone and carbonaceous shale; the Hutian in upper Carboniferous (C2ht) developed pink
