摘要
上地幔硅酸盐矿物中的磷含量是磷在地球深部的存在及循环研究的重要内容之一,对于理解和深刻认识上地幔磷的地球化学特征具有重要意义。对石榴子石、橄榄石及辉石中磷的固溶度进行详细的研究将会丰富深部磷循环的研究内容,为理解磷的深部地球化学行为提供科学依据。本文基于天然样品和高温高压实验研究结果,分析总结了上地幔硅酸盐矿物中磷的含量及磷进入硅酸盐矿物结构中的机制,探讨了压力、温度、氧逸度及矿物结构对上地幔硅酸盐矿物中磷含量的影响。
The research on phosphorus contents in silicate minerals in the upper mantle is one of important studies on the existence and circulation of phosphorus in the deep Earth.It is of great significance for deep understanding the geochemical characteristics of phosphorus in the upper mantle.The detailed researches on solid solubilities of phosphorus in garnet,olivine and pyroxene will enrich research contents of the phosphorus cycling in the deep Earth and provide scientific theoretical basis for deeply understanding the geochemical behavior of phosphorus in the deep Earth.Based on previous research results of natural samples and high-pressure and high-temperature experiments,in this paper,we have summarized the phosphorus contents of main silicate minerals in the upper mantle and the mechanism of phosphorus entering into the lattice of silicate minerals,and have discussed the influences of pressure,temperature,oxygen fugacity and mineral structure on the phosphorus contents of silicate minerals in the upper mantle.
