| 摘 要： | 本文依据宝鸡岩体颜家河超单元各单元的岩石组构、矿物成分、岩石化学和地球化学等方面的资料，研究了它们由早到晚的变化特征，并将各种特征有机地联系在一起，发现该超单元岩浆从早到晚存在着反序演化的特点，即由偏酸性岩浆向偏基性岩浆演化，并建立了该超单元的岩浆演化模式。

| Abstract: | According to the composition and texture of rock mineral component, rock chemistry and geochemistry of every unit of Yan Jiahe ultra-unit, Bao ji magmatic body, whose characteristics in every stages are studied in this paper. It is found that there is anti-sequence evolution, from much acidic magma to much alkalic magma, in this magpeatic body. As a result,the magmatic evolution model of the ultra-unit is established. |
