摘要:地幔交代作用是岩石圈演化的重要方式之一，显性交代可为地幔交代作用提供直接证 据。太行山断裂以东发生了明显的岩石圈破坏，鹤壁地区位于太行山构造带上，产出有大量地 幔捕虏体。本论文在土门金伯利岩中地幔捕虏体内发现了显性交代成因的磷灰石单矿物。通 过体视镜观察、扫描电镜分析和电子探针成分分析工作，证实了橄榄岩捕虏体中发育有被辉石 包裹的磷灰石。这种形态的磷灰石无疑为地幔交代成因，是华北克拉通岩石圈地幔经历显性 交代作用的直接证据，这可能与华北克拉通破坏（岩石圈地幔的减薄）有着密切联系。

Abstract:Mantle metasomatism is one of the important ways of lithosphere evolution. Dominant metasomatism can provide direct evidence for mantle metasomatism . The main destruction area of the North China Craton is to the east of the Taihang Mountain structural belt，and Hebi area of Henan Province is located on the Taihang Mountain structural belt，and there are a lot of mantle xenoliths. In this paper，a dominant metasomatic apatite single mineral was found in the mantle xenoliths of Tumen kimberlite . By means of stereoscopic observation，scanning electron microscopy and electron probe microanalysis，it is confirmed that there are apatite inclusions in peridotite xenoliths. This kind of apatite is undoubtedly of mantle metasoma- tism，which is the direct evidence of dominant metasomatism of lithospheric mantle in the North China Cra- ton，which may be closely related to the destruction of the North China Craton（thinning of the lithospheric
