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
