It is indicated that source materials of type of lateritic gold deposit are rich-SiO 2 (quartz, SiO 2),rich-Fe and rich-Au ores or rocks.

分析指出，本类红土型金矿的矿源物质是高硅质(石英SiO2)、富铁质的富金矿石。

Combined with available data, it is comidered that the sourcerock of biotite--leptynite might be intermediate-acid volcanic material of ca.2.7 Ga, and that of migmatized leptite and quartzite might come from granitic crust older than 3.0 Ga. The iron formation was formed on the continental crust base at about 2.7 Ga, and was immediately metamorphosed for the first time.

结合已有的研究资料可以认为，黑云变粒岩的原岩来自2.7 Ga左右的中酸性火山物质，浅粒岩和石英岩的原岩来自3.0 Ga以上的花岗质地壳物质；含铁建造形成于陆壳基底之上，形成时间约2.7 Ga，并于2.5—2.7 Ga之间发生首次变质作用。

We think main metamorphic rock types of this area include mited granite ,mixed metamorphic rock,leptite,etc.

认为变质岩中混合花岗岩、混合岩化变质岩、变粒岩、浅粒岩、黑云斜长片麻岩等为本区的主要变质岩类型；沉积岩以云岩、硅质岩和石英砂岩为主；火成岩脉主要为辉绿岩、煌斑岩和闪长玢岩。

The zircon was dated by using the technique of single-zircon stepwise evaporation-deposition with a thermal ion mass spectrometry (Bernd Kober, 1986 and 1987). The zircon ages are 2.60-2.54 Ga for biotite-leptynite, 3.36-2.62 for mimatized leptite, and 3.53-3.08 Ga for quartzite from the iron formation.

用热离子质谱计双带源蒸发—沉积测定单个锆石晶体年龄的方法对弓长岭含铁建造中黑云变粒岩、混合岩化浅粒岩和石英岩中的锆石作了测定，获得了2.60—2.54 Ga，3.36—2.62 Ga和3.53—3.08 Ga等年龄数据。

Differences in composition of the magmatic rocks and their geological and structural setting are the main factors resulting in differences in geological characters between the 414 deposit and Limu orefield.

在这些矿区范围内，均发育规模不等的黑钨矿石英脉型矿床。本文试图通过两矿床与成矿有关的花岗岩体及矿床特征的对比研究，说u近戊矿床成矿待

The growth of C. japonica grow well in the Limy dolomite, then in quartz sandstone, sandstone and shale with coal, purple sandstone and metamorphic sandstones, but poor in the quaternary clay.

日本柳杉在灰质白云岩上生长最好，在石英砂岩、煤系砂页岩、紫色砂岩、变质砂岩上居中，而第四纪粘土生长较差。

Content variety of clast is big, quartz is 20-75％, feldspar is 0-38％, lithoclast is 1-50％, and matrix is 22％.

碎屑含量变化大，石英为20-75％、长石0-38％、岩屑1-50％、杂基22％。

The diagenetic characteristics of Chang 6 sandstone of the Upper Triassic in Yanchi-Jiyuan area of the western Ordos Basin show that this set of sandstones are in the early A period of the late diagenetic stage at present and controlled by the acidic diagenetic environment, where the abundant diagenetic phenomena including widespread dissolution of feldspar and lithoclast, secondary enlargement of quartz and well-developed early chlorite film can be observed.

对鄂尔多斯盆地西部盐池-姬塬地区三叠系延长组长6砂岩成岩作用特征的研究表明，该套砂岩目前处于晚成岩阶段A期的早期，受酸性成岩环境控制。长石类易溶颗粒普遍发生溶蚀。石英次生加大发育。特别是早期形成的绿泥石粘土膜非常发育。

Lithologically, the content quartz is lower than those of feldspar and detritus, and the cement is dominated by clay, which gives the feature of low compositional maturity and low textural maturity.

馆上段储层岩性以岩屑质长石细砂岩为主，其次为中细砂岩和粉砂岩，岩石中石英含量低，而长石、岩屑含量高，胶结物以泥质为主，表现出低成分成熟度和低结构成熟度的特点。

Colored by iron, Amethyst is a variety of macrocrystalline Quartz that occurs in transparent pastel roses to deep purples.

各种各样的紫水晶都是粗结晶石英，因内含的铁物质而变成色彩多姿，颜色由透明如水的粉红色过渡到深紫色。

On closer examination, though, this is not a vote for multilateralism but just the opposite.

仔细审视后我们发现，这并非是对多边主义投出的赞成票，而是恰好相反。

Uncovering their weak spots, so I can defeat them.

揭露出他们的弱点，这样我就可以打败他们了。
