The solubility of spodumene in haplopgranitic melts and its mineralization implication
This study conducted high-temperature and high-pressure experimental studies on the solubility and influencing factors of spodumene in haplogranitic melts using a rapid quenching high-temperature and high-pressure experimental device under conditions of lOOMPa and 650~850℃.These results indicate that temperature is the most important factor affecting the solubility of spodumene in haplogranitic melts,followed by aluminum saturation index.The Na/K ratio of the melt has almost no effect on the solubility of spodumene.Based on existing data,establish the relationship between the solubility of spodumene and temperature,aluminum saturation index(ASI):logLi2O(%)=-0.61 ×(1000/T)+0.53 × ASI+0.10,R2=0.60 Where T is the in Kelvin temperature.This relationship can be used to quantify the crystallization temperature of spodumene or to evaluate the mineralization potential of granitic pegmatites.The results of this study indicate that the mineralization potential of lithium in pegmatite deposits is limited by the lithium content in the initial magma and the crystallization temperature of the pegmatite.
