Based on intensive petrographic, petrologic, fluid inclusion and geochemical work of the past 2 years (see progress report), we will now try to constrain in detail the late-stage evolution of the Mont Saint- Hilaire complex during which an unusual mineral wealth developed. Representative mineral chemistry and stable carbon and oxygen data of late-stage carbonates and detailed mineral chemistry data of Na-Al-silicates will be collected. These will serve as key tools for reconstructing intensive parameters like temperature, pH and activities of silica, NaCl and H2O of late-stage assemblages. We will compare these data to intensive parameters in the earlier crystallized rocks from Mont Saint-Hilaire (see progress report). Relating the conditions reconstructed for the magmatic stage to the postmagmatic hydrothermal stage, continuous and discontinuous behavior in evolutionary trends will be distinguished. We will thus try to distinguish between open and closed system episodes and compare our results to similar assemblages from other alkaline complexes in order to understand and – where possible – quantify the chemical and physical parameters which control the development of these unusual late-magmatic/hydrothermal mineral assemblages.

在过去2年大量岩石学、岩石学、流体包裹体和地球化学工作的基础上（见进度报告），我们现在将试图详细地限制Mont Saint- Hilaire杂岩的晚期演化，在此期间，一种不寻常的矿产资源得到了发展。收集晚期碳酸盐具有代表性的矿物化学和稳定的碳氧数据以及na - al硅酸盐的详细矿物化学数据。这些将成为重建后期组合的温度、pH和二氧化硅、NaCl和H2O活性等密集参数的关键工具。我们将把这些数据与圣伊莱尔山早期结晶岩石中的密集参数进行比较（见进度报告）。将岩浆期和岩浆期后热液期重建的条件联系起来，区分演化趋势的连续性和不连续行为。因此，我们将尝试区分开放和封闭系统片段，并将我们的结果与其他碱性复合体的类似组合进行比较，以便了解并在可能的情况下量化控制这些不寻常的晚岩浆/热液矿物组合发育的化学和物理参数。
