铁橄榄石

It is made of Magnesium and Iron Silicate, and it is a member of the Chrysolite mineral family.

它是由镁，矽铁，它是一个成员橄榄石矿物家庭。

Since olivine is silica-unsaturated, quartz and olivine never coexist in the same rock. Therefore, in mantle peridotite and other ultramafic rocks, primary quartz can never be found.

由于石英和非饱和SiO_2的橄榄石不能共生，因此在地幔橄榄岩和超镁铁岩中不存在原生石英。

III. silicate mineral contain iron, include olive stone , black column stone , common picrite etc.

三、含铁硅酸盐矿物：有橄榄石、黑榴石、十字石、黑柱石、普通辉石等。

III. silicate mineral contain iron mosaic tile , include olive stone, black column stone, common picrite etc.

三、含铁硅酸盐矿物：有橄榄石、黑榴石、十字石、黑柱石、普通辉石等。

The electron microprobe analyses show that there are distinct differences between two types of olivine in the aspects of the FeO/MnO ratio, the species of inclusion minerals, the concentrations of Fe an Ni in kamacite and taenite inclusions.

电子探针成分分析结果表明，两种橄榄石中的 Fe O和 Mn O比值，包体矿物种类，包体铁纹石和镍纹石中 Fe，Ni的含量等，均有较大区别。

The original alkalic series of basalic magma evolutes into trachybasalt through crystallization differentiation of olivine and pyroxene, and the trachybasalt is transformed into alkalic rhyolite with remarkable Eu, Sr, Ba, Ti, P nagetive abnormalities through strong crystallization differentiation of plagioclase and also pyroxene Ti Fe oxides and apatite, all together leading to the loss of neutral (SiO 2=57%～63%) andesite and trachyandesite in the volcanic rocks in this area and appearance of bimodal volcanic rock combination feature.

原始碱性系列玄武质岩浆经橄榄石、辉石的结晶分异，向粗面玄武岩演化；粗面玄武岩经斜长石强烈的结晶分离作用，还有辉石、钛铁氧化物和磷灰石的分离结晶作用形成具显著Eu、Sr、Ba、Ti、P负异常的碱性流纹岩，导致本区火山岩缺失中性(SiO2=57%～63%)的安山岩和粗安岩，呈现双峰式火山岩组合的特点。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
