摘要
金红石矿床含矿岩石常量元素总体上与玄武岩接近，但以低硅、高钛、高ＣＯ２、高碱度为特征。矿床微量元素与地壳的差别显著。稀土元素较高，分布模式呈轻稀土富集型，Ｅｕ 一般为正常型与碧玄岩最接近。Ｔｉ与Ｂａ、Ｃｏ、Ｐｂ、Ｓｒ、Ｔｈ、Ｖ、Ｙ 及稀土元素呈正相关，与Ｃｒ和Ｎｉ呈负相关。δ３４Ｓ多数与（超）铁镁质岩石接近，最大值小于且靠近现代海水。
The most common elements are close to basalt's in Rocks of containing ore, but SiO 2 is lower and TiO 2, CO 2 and alkalinity are higher. The trace elements are very different from crust's. The rare earth elements are higher, the distribution pattern is light rare earth elements concentration type, Eu is usually normal type, they are closest to basanite. Ti correlates positively with Ba, Co, Pb, Sr, Th, V, Y and rare earth elements, negatively with Cr and Ni. Most of the δ 34 S datum are close to ultramafic rock and mafic rock, the biggest of all is less than and close to modern seas water's.
