流纹

We now look at this rock is red, of course, not the blood of the ancient craftsmen, because Tiger is the acid rock rhyolite, its original stone is red.

我们现在看这块石头是红颜色的，当然不是古代工匠的鲜血，因为虎丘的岩质是酸性流纹岩，它的石质原本就是红色的。

Igneous rock produced by eruption and solidified on or near the earth's surface; rhyolite or andesite or basalt.

火成岩产生于火山喷发和在地表或接近地表的地方凝固；流纹岩或安山岩或玄武岩的。

According to the fact that dawsonite and ankerite are the authigenic minerals forming at latest in sandstone, CO2 infilling was relatively late, possibly 46.2 ± 2.1 Ma or later.

CO2注入晚于油气大规模充注，最早时间为90Ma，与研究区花岗岩、流纹岩等岩浆岩年龄相差较大。

The tests and studies on the rhyolite filtering material show that the functions of the rhyolite material are superior to that of the arenaceous quartz, and the rhyolite flitering material is worth further studying and developing.

对流纹岩滤料的初步试验研究表明，流纹岩滤料的性能明显优于石英砂，是比较理想的天然无机滤料，具有进一步研究开发价值。

The rock types include rhyolite,dacite and sedimentary volcaniclastic rocks,among which the lava tuff breccia was newly discovered in the 1∶ 50 000 region.

岩石类型为流纹岩、英安岩和沉火山碎屑岩，其中的熔结角砾凝灰岩是本次 1∶ 5万区调中的新发现。

Sub-volcanic rocks include andesitic porphyrite, rhylitic porphyry, cryptoexplosive breccia as well as autobreccia etc.(2) Volcanic lithofacies——through the observation of cores, identification of thin sections and interpretation of well logs and seismic data, there are 8 kinds of lithofacies for the volcanic rocks of Yingcheng Formation are identified: fallout facies, effusion facies, pyroclastic flow facies, base surges facies, lahar facies, eruption-sedimentary facies, subvolcanic facies and extrusion facies.(3) Three types of eruption——i. e. explosion, effusion and surge.(4) Two kinds of eruptive environments——Subaerial (e. g. volcano in Well Shangshen 3) and subaqueous .(5) Three remarkable volcanic apparatus in Shengping-Wangjiatun area——layered, micro-shield and cone volcanoes according to volcanic processes and lithofacies distribution.

次火山岩有安山玢岩、流纹斑岩、隐爆角砾岩及自碎角砾岩等；(2)火山岩相——通过岩芯观察、镜下鉴定、测井与地震资料解释，营城组火山岩中发育8种岩相类型，即爆发空落相、溢流相、火山碎屑流、基底涌流相、喷发沉积相、火山泥石流相、侵出相和次火山相等；(3)火山喷发的形式——有爆发、溢流和涌流三种；(4)火山喷发环境——有陆上(如尚深3井火山)和水下两种；(5)火山机构类型——根据火山作用特点和岩相分布特征，在升平—汪家屯地区识别出三类截然不同的火山机构，即层火山、微型盾火山和渣锥火山。

Rhyolitic volcanic rocks are generally characterized by rich alkali, silicon, aluminum,and poor calcium, magnesium. They have relatively high Rb,Th and rather low Ba,Sr,Ti,P,and exhibit obviouslv negative europium anomaly (δEu=0.16~0.44).The εNd values of the rhyolitic volcanic rocks range from -5.93 to -2022.Basalts and rhyolites in different cycles show clear geochemical variance.

流纹质岩石总体具富碱、富硅、富铝，贫钙、贫镁特征，其Rb、Th等元素的含量较高，而Ba、Sr、Ti、P等元素含量则明显偏低，并具显著的铕负异常（εEu=0.16'0.44），岩石的εNd值变化于-5.93~~-2.22.I、II旋回玄武岩和流纹岩在地球化学特征上均具明显变异。

Xiangshan volcano-intrusive complexes is the wall rock of the biggest volcanic-rock uranium ore deposit in China, and the main body is rhyolitic porphyroclastic lava, accompanied by hypahyssal or ultra-hypabyssal intrusive rocks such as dacite-porphyry and granite-porphyry Jiulongzhang volcano-intrusive complexes are dominantly rhyolitic welded tuff, accompanied by dacite-porphyry and quartz monzonite-porphyry, and so on, and the uranium resources are being assessed.

相山火山－侵入杂岩是华南地区最大的火山岩型铀矿赋矿围岩，其主体岩石为流纹质碎斑熔岩，浅成－超浅成侵入岩有英安斑岩、花岗斑岩等；九龙嶂火山－侵入杂岩的铀资源潜力尚待评价，主体岩石为流纹质熔结凝灰岩，浅成－超浅成侵入岩有英安斑岩、石英二长斑岩等。

The activities of Wangtian′e volcano lasted for three periods:①The Changbai period volcanic rocks consisting mainly of trachybasalt with small amount of alkalic basalt and basaltic trachyandesite;② The Wangtian′e period can be further divided into early and late periods, the early period volcanic rocks consisting of basaltic trachyandesite and trachyte, the late period volcanic rocks cosisting of alkalic rhyolite;③The Hongtoushan period volcanic rocks consisting of alkalic rhyolite.

望天鹅火山活动从早到晚分为三期：①长白期以粗面玄武岩为主，少量碱性玄武岩和玄武质粗安岩；②望天鹅期又分早晚两个亚期，早期玄武质粗安岩和粗面岩，晚期碱性流纹岩；③红头山期碱性流纹岩。

Flow lines --lines on the surface of painted sheet, caused by either incomplete leveling of the paint or telegraphing of imperfections on the metal surface.

流纹线—在彩涂板表面上的线。由涂料的不完全流平造成的或在钢带表面的不完全性造成的。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
