Geochemistry of clinopyroxene megacrysts, xenocrysts, and phenocrysts in diab...

We report the major, rare earth, and other trace element compositions of clinopyroxenes from two Leg 140, Hole 504B diabase dikes. These pyroxenes reflect a complex history of...本数据集报道了来自大洋钻探第140航次（Leg 140）504B钻孔（Hole 504B）两处辉绿岩岩脉的单斜辉石（clinopyroxenes）的主量元素（major elements）、稀土元素（rare earth elements）及其他微量元素组成。这些辉石记录了一段复杂的演化历史……
