摘要
The nonlinearity between the deposit characteristics and multi-geological factors by BP network simulation is studied.The metallogenic prediction flow chart by BP neural network is set up.Taking Gaosong mining area as an example,the geological background of mine,ore-controlling factors and geochemical characteristics are analyzed.Metallogenic prediction model of multi-geological factors is built.Four scale-I metallogenic prospective areas(ore-forming favorability>0.6) and two scale-II metallogenic prospective areas(0.6>ore-forming favorability>0.5)are delineated and verified in actual situation by exploration.
