The compositional evolution of magmatic-hydrothermal fluids from the SnW mineralized Cornubian batholith was investigated via in situ fluid inclusion LA-ICP-MS microanalysis and reveals a large degree of variation between intrusive stages and at the sample scale, with complexities due to superposition of several mechanisms affecting fluids chemistry during the protracted evolution of the batholith. Despite large ranges of salinities (from <1 wt% to 48 wt% NaCl), the effects of individual processes such as magmatic differentiation, fluid saturation and boiling, fluid mixing and dilution can all be discerned on the basis of fluid inclusion trace element geochemistry combined with detailed petrography and microthermometry.

揭示岩浆分馏、流体相分离和稀释对 Cornubian 基岩岩浆热液成分的影响（英格兰西南部）


通过原位流体包裹体 LA-ICP-MS 微分析研究了来自 SnW 矿化 Cornubian 岩基的岩浆热液流体的成分演化，揭示了侵入阶段和样本尺度之间的很大程度的变化，由于多个因素的叠加而变得复杂。在岩基的长期演化过程中影响流体化学的机制。尽管盐度范围很大（从 <1 wt% 到 48 wt% NaCl），但岩浆分异、流体饱和和沸腾、流体混合和稀释等各个过程的影响都可以根据流体包裹体微量元素地球化学来辨别结合详细的岩相学和显微测温。
