在过去的十年中，能够在严格控制的温度（至 1,700°C）下产生高达 50 kbar 压力的固体介质高压装置的出现，导致了在高压条件下对简单系统和天然岩石的直接实验研究的迅速加速。这些研究在阐明玄武岩之间可能的遗传关系方面取得了丰硕的成果，现在有可能建立一个相当完整和自洽的模型，其中橄榄岩地幔通过部分熔融、岩浆分离和进一步岩浆分馏的过程，可能产生成分从橄榄石黄长岩霞长岩到橄榄石拉斑长岩的液体。
Over the past ten years, the availability of solid-media high pressure apparatus capable of generating pressures up to 50 kbar at closely controlled temperatures (to 1,700°C) has led to a rapid acceleration of direct experimental studies of both simple systems and natural rocks under high pressure conditions. These studies have been most fruitful in elucidating possible genetic relationships among basalts and it is now possible to erect a rather complete and self-consistent model in which a peridotitic mantle, by processes of partial melting, magma segregation and further magma fractionation, may produce liquids ranging in composition from olivine melilite nephelinite to olivine tholeiite.
