由于这种作用的影响，使钾质煌斑岩的源区地幔处于地温梯度高、氧逸度高的不稳定状态。
Under the influence of the subduction, the source mantle of the potassic lamprophyres has a high geothermal gradient and oxygen fugacity.
低ree组和高ree组煌斑岩分别是交代富集地幔约10%和4%部分熔融的产物。
Low REE group and high REE group lamprophyres are 10% and 4% partial melting of the metasomatic enriched mantle.
