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.

这项研究包括利用定量方法研究火成岩堆积中的压实作用。拟议的研究将包括发展压实的数值模型，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，积云堆内的热损失率和生成率，以及晶体的积累率。理论模型将有助于理解层压、主体主要元素和微量元素组成、矿物组成以及由附属相表示的液-流体组成之间的相关性。最初的模型将被设计成广泛适用于所有类型的由晶体积累形成的岩石。
