Abstract： Yifen-Fengxin area in Jiangxi province is an important granite type lithium mining area in China. Gangkou granite lithium deposit in Fengxin county is located at the eastern end of the Yifeng-Fengxin lithium mining field. By summarizing the regional geological background， metallogenic geological conditions and geological characteristics of the Gangkou mining area， it is found that the prospecting indicators for this type of deposit are mainly ore-forming geological body indicators， structural indicators， alteration indicators， and heavy sand mineral indicators.

Keywords： lithium deposit; geological characteristics of deposit; prospecting indicators; Gangkou granite lithium deposit

江西省奉新县港口花岗岩锂矿（以下简称港口矿区）大地构造位置位于江南隆起带九岭逆冲隆起南缘，北部和南部分别为武功山隆起和九岭隆起，中部为萍乐坳陷带，隆起与坳陷之间自北往南发育宜丰—景德镇、萍乡—广丰两条区域性深断裂控制着区内地层岩相分布[1]。（剩余2630字）
