摘要
洋县铁河石墨矿区大安沟矿段是一个大型晶质石墨矿床,处于秦岭褶皱系印支褶皱带白水江—白河褶皱束的中部,南界以马道断裂为界与康县—略阳华力西褶皱带分开,北界以白水江—留坝断裂为界与南秦岭印支褶皱带留凤关—金鸡岭褶皱束相邻。该石墨矿床赋存于中—上志留统第五岩性层内,属于变成矿床。
Located in the central part of the Baishuijiang-Baihe fold bundle of the Indosinian fold belt that belongs to the Qinling fold system, the Da＇ngou ore block of Tiehe graphite mine is a large scale of crystalline graphite ore body. The Maodao fault separates the graphite mine and the Hereynian Kangxian-Lueyang fold at the south and the Baishuijiang-Liuba fault is the north boundary to the Liufengguan-Jinjiling fold bundle of the Indosinian fold belt in the south Qinling. The graphite deposit locates in the fifth lithographic layer of the Middle-upper Devonian System, attributing to regional altered deposit.
