AIJINGSHAN STRONTIUM DEPOSIT IN LISHUI,JIANGSU: A MULTI PARAMETER ORE HUNTING MODEL

江苏溧水爱景山特大型锶矿床位于溧水火山岩盆地的边缘，受Ｆ２断层、龙王山组晶屑凝灰岩、安山玢岩控制。根据锶矿为强电阻体，矿石与围岩电性差异大，龙王山组晶屑凝灰岩中锶的平均含量高（１６２１×１０－６），安山玢岩含锶量更高（４５９７×１０－６），矿区生物地球化学异常显著，常见的植物生态呈现变异现象等特征，研究归纳出溧水爱景山锶矿床综合技术方法找矿模型，在所预测的远景区中，发现了锶矿。

Situated on the margin of the Lishui volcanic basin, Jiangsu, the Aijingshan strontium deposit is controlled by the F 2 fault and the crystal tuff and andesitic porphyrite of the Longwangshan group. The deposit is known for higher resistivity of the ores than the wall rocks, high mean content (1612 x 10 -6 ) of strontium in the tuff and ever higher (4597 x 10 -6 ) in the porphyrite, and prominent biogeochemical anomaly associated with the plant ecologic variation in the mining area. All these parameters were analyzed and summed up in order to establish a multi parameter ore hunting model with which new strontium mineralizations have been hunted in the prospective area.
