Petrological and geochemical studies of lamproites can provide useful insights into the nature of their lithospheric mantle sources, but their geochemical and mineralogical diversity has complicated our understanding of their primary/parental melt composition, volatile (CO₂, H₂O) inventory and magmatic evolution. To help address this issue, we present a detailed study of different generations (primary, pseudosecondary, secondary) of crystal, and melt and fluid inclusions in olivine, Cr-spinel and perovskite from three olivine lamproites in the Ellendale Field of the West Kimberley Province (Australia) in order to understand the composition and evolution of their parental magmas.

Melt inclusions in the different host minerals and from each of these localities are broadly similar to each other and consist of glass, alkali/alkali-earth (Mg-Ca-K-Na-Ba) carbonates, phosphates and chlorides, in addition to minerals typical of lamproite groundmass (fluorapatite, perovskite, phlogopite, diopside, wadeite, Mg-ilmenite, Fe-Mg-Ti-Cr spinel). The dominant volatile species in the melt and fluid inclusions is CO₂ based on Raman data. Heating experiments of melt/fluid inclusions in olivine show significant phase transformations in which the carbonate may separate into an immiscible carbonate-rich sulphate-bearing fraction or exsolve a CO₂ fluid.

Our results indicate that carbonates, along with alkali/alkali-earths, halogens and sulphur, became progressively concentrated in the West Kimberley lamproitic magmas during crystallisation, leading to the entrapment of a complex array of daughter minerals, some not previously reported from lamproites and, in some inclusions, immiscible carbonate melt. The widespread occurrence of daughter carbonates in melt/fluid inclusions in lamproite minerals is at odds with their apparent paucity in the lamproite groundmass. The presence of carbonate and the abundance of CO₂-rich and H₂O-poor melt and fluid inclusions are attributed to the preferential partitioning of CO₂ into the vapour and retention of H₂O in the magma during degassing, coupled with H₂O loss by post-entrapment modification of the inclusions through H⁺ diffusion.

Lamproites 的岩石学和地球化学研究可以为了解其岩石圈地幔来源的性质提供有用的见解，但它们的地球化学和矿物学多样性使我们对其原生/母体熔体成分、挥发性（CO ₂、H ₂ O）存量和岩浆演化的理解变得复杂. 为了帮助解决这个问题，我们详细研究了西金伯利省 Ellendale 矿区的三种橄榄石中的橄榄石、Cr-尖晶石和钙钛矿中不同世代（初级、伪次级、次级）晶体、熔体和流体包裹体（澳大利亚）以了解其母岩浆的组成和演化。

不同宿主矿物中的熔体包裹体和来自这些地方的每一个都大体相似，除矿物外，还包括玻璃、碱/碱土 (Mg-Ca-K-Na-Ba) 碳酸盐、磷酸盐和氯化物典型的灯铁矿基体（氟磷灰石、钙钛矿、金云母、透辉石、钙钛矿、镁钛铁矿、铁镁钛铬尖晶石）。根据拉曼数据，熔体和流体包裹体中的主要挥发性物质是 CO _{2 。}橄榄石中熔体/流体包裹体的加热实验显示出显着的相变，其中碳酸盐可能分离成不混溶的富含碳酸盐的含硫酸盐部分或溶解 CO ₂流体。

我们的研究结果表明，碳酸盐以及碱/碱土、卤素和硫在结晶过程中逐渐集中在西金伯利灯火岩岩浆中，导致夹带一系列复杂的子矿物，其中一些以前从未从灯火石中报道过，并且，在一些包裹体中，不混溶的碳酸盐熔体。灯火石矿物的熔体/流体包裹体中普遍存在子碳酸盐，这与它们在灯火石基体中的明显缺乏相矛盾。_{碳酸盐的存在以及富含 CO 2}和贫H ₂ O 的熔体和流体包裹体的丰度归因于 CO ₂优先分配到蒸气中并保留了 H ₂脱气过程中岩浆中的 O，以及通过 H ⁺扩散对夹杂物进行后包埋改性而导致的H _{2 O 损失。}
