Compaction of Igneous Cumulates

小行星9417144 本研究采用定量方法研究火成岩堆积层的压实作用。 拟议的研究将包括开发压实的数字模型，可用于确定若干参数的重要性，这些参数包括：积云密度随高度的变化、积云堆内热量损失和产生的速率以及晶体积累的速率。 该理论模型将有助于理解层压，散装主要和微量元素组成，矿物组成，和液体流体组成所示的辅助相之间的相关性。 最初的模型将被设计为广泛适用于所有类型的岩石形成的晶体积累。

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.
