图9 伏岭花岗岩基于瑞利分离结晶的微量元素模拟 由于Rb、Sr、Ba主要受控于主要矿物,此处分离相不考虑副矿物的影响,FC1分离矿物相组合:35%石英+40%斜长石+15%钾长石+5%黑云母;分离结晶演化趋势线以10%为间隔。各矿物的Rb、Sr、Ba 分配系数引自文献[50]。

Fig.9 Simulation of trace elements in Fuling granite based on Rayleigh separation crystallization Since Rb, Sr and Ba are mainly controlled by major minerals, the effect of accessory minerals is not considered in the separated phase here, and FC1 separates the mineral phase combination: 35% quartz + 40% plagioclase + 15% K-feldspar + 5% biotite; The trend line of separation crystallization evolution is spaced by 10%. The distribution coefficients of Rb, Sr and Ba for each mineral are quoted from references [50].
