9417144 Boudreau This research involves a study of compaction in igneous cumulates utilizing a quantitative approach. the proposed study would include development of numerical models of compaction that can be used to determine the importance of several parameters including: variation in cumulate density with height, the rate of heat loss and generation within the cumulus pile, and the rate of accumulation of crystals. The theoretical model will aid in understanding correlations between lamination, bulk major and trace element composition, mineral compositions, and the liquid-fluid compositions as indicated by accessory phases. Initial models will be designed to be broadly applicable to all types of rocks formed by accumulation of crystals.

9417144 Boudreau 这项研究涉及利用定量方法研究火成岩堆积物的压实。 拟议的研究将包括开发压实数值模型，该模型可用于确定几个参数的重要性，包括：积云密度随高度的变化、积云堆内热损失和生成的速率以及晶体的积累速率。 该理论模型将有助于理解层状、大量主量和微量元素成分、矿物成分以及辅助相所示的液体-流体成分之间的相关性。 初始模型将被设计为广泛适用于晶体堆积形成的所有类型的岩石。
