| 摘 要： | 金刚石母岩可以是榴辉岩、辉石岩、橄榄岩等多种岩石,它们与金刚石都是在地幔深处形成的,并上侵最终固结于地壳中。母岩中的金刚石等矿物在地壳中又发生准稳定生长。地壳中金伯利岩和钾镁煌斑岩岩浆作用对金刚石母岩侵入体进行改造,使原生金刚石发生破碎、溶解、再生长等一系列变化,并形成巨晶、劣质金刚石和黑金刚石等新类型,这些现象不是在金刚石母岩形成之初发生的。 |
| 关 键 词： | 褶皱带 稳定地块 金刚石远景 层状侵入体 金伯利岩筒 原生岩浆 |

| Abstract: | The data reported in this article show that rocks containing diamonds such as eclogite, pyroxenite, and peridotite have undergone different p-T conditions before they were brought up to the surface. Diamond was originally formed at deep in the mantle. It was then transformed to its final stage in the crust where the metastable growth of diamond and associated minerals has taken place. During kimberlite and lamproite magmatism xenoliths of diamondiferous rocks were engulfed by ascending magma. The inherited diamonds were transformed by processes including dissolution, replacement, and overgrowth. |
| Keywords: | fold belt craton diamond potential layered intrusion kimberlite pipe primary magma |
