石英

Beginning with areal geologic background, the authors have discussed the features of quartz vein at Rujigou mining area Ningxia, such as lithology, contact correlation with wall rock, scales, space-time distribution, attitudes, assemblage, mineral inclusion, and have compared the quartz vein with the veins within other coalfields and coal measures.

笔者从地质背景入手，较详细的论述了汝箕沟矿区石英脉的岩性、与围岩的接触关系、规模、时空分布、产状、组合、矿物包裹体等发育特征，比较了该区石英脉与诸多煤田和煤系中脉岩的差异。

SHRIMP U-Pb concordia ages of the cores of rounded zircons are 620 and 219 Ma, suggesting that the parental magma for the quartz diorite porphyry may have been derived from partial melting of basement materials of the South China block that had been modified by ultrahigh-pressure metamorphism.

具有细微震荡环带岩浆锆石的SHRIMP U-Pb年龄(117.7±1.6 Ma)显示该石英闪长斑岩体的形成时间为早白垩世；浑圆状锆石核部SHRIMP U-Pb谐和年龄为620 Ma和219 Ma，这表明该石英闪长斑岩的母岩浆可能起源于经历了超高压变质作用改造的华南地块基底物质的部分熔融。

Based on synthetic information, the authors infer the silicic alterative zones locate in both sides of quartz porphyry intrusive body.

综合信息推断出硅化蚀变带出现在石英斑岩侵入体两侧，经过工程控制在石英斑岩南北两侧发现两条矿带，证实找矿模型正确，并发现金矿脉两条，计算储量为5.2 t。

Background: China is abundant in quartz sand.

一、项目背景：我国的石英砂资源较为丰富，但石英砂在加工过程中产生的尾泥尾砂，不仅占用大量的土地，而且对沿河流域的生态环境造成了严重影响。

I plant mainly produces quartz sand, quartz powder, mica products.

金矿化主要呈自然金和少量其它金矿物显微包体形式，存在于各阶段黄铁矿、黄铜矿与石英晶粒间，少数产于石英或其它硫化物中。

Ore bodies consists of Au-bearing quartz vein s and the alteration rocks between them and ore grade depends on number of the quartz vein.

矿床由含金石英脉与其间蚀变岩组成，品位高低决定于含金石英脉的数量。

The Rose Quartz Kingdom is not the only mineral that holds pink tones of creation; Rhodocroshite, ruby, and pink tourmaline are other minerals hosting the pink ray.

玫瑰石英王国（译注：玫瑰石英即粉水晶）不是唯一的掌握着粉红光音调的矿物；红纹石、红宝石和粉红电气石也掌握着粉红光线。

P72 Formation process of roddings: B type lineation is formed by the fold rolling of the thin-bedded vein quartzite or quartzite intercalated in the rocks.

Q 0 10cm 2。杆状构造形成过程：B型线理，由岩层中夹薄层脉石英或石英经褶皱的辗滚作用而形成。

Shagou vein-type Ag-Pb-Zn ore deposit in the south margin of North China Craton is composed of vein and replacement ore types.

豫西沙沟薄脉状Ag-Pb-Zn硫化物矿床位于华北地台南缘熊耳山地区，由硫化物石英脉和石英-碳酸盐-云母蚀变岩这两种矿化类型组成。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
