火成岩

Three main rock types make up the geology of Singapore: igneous, sedimentary and alluvium.

形成新加坡地质的三种主要岩石类型：火成岩、沉积岩和冲积岩。

A vitreous mineral consisting of sodium aluminum silicate and sodium chloride in crystalline form; occurs in igneous rocks.

一种玻璃质矿物，由钠铝硅酸盐和氯化钠组成，呈晶体状，见于火成岩中。

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。

One of the main purposes of igneous rocks petrography is to get an entire classification of magma and igneous rocks system.

火成岩岩类学研究的主要目的之一在于获得岩浆/火成岩系统的一套完整的分类清单。

During more than one hundred years history of igneous rocks petrography, many petrologists have put forward hundreds of classification plans, tables and diagrams.

在一百多年的火成岩发展史中，许许多多的岩石学家们提出了不下几百个火成岩分类的方案、表格、图解。

New reliable UPb age dates of the extensive Cretaceous igneous rocks in the eastern Himalayas suggest that these rocks were emplaced at about 132 Ma, and may represent the erosional and/or deformational remnants of the newly identified ComeiBunbury large igneous province.

新的可靠的锆石UPb年龄指示喜马拉雅带东部措美地区大面积出露的白垩纪火成岩侵位于132 Ma左右，代表了新近在藏南和澳大利亚南西部识别出的经历了强烈变形和深位侵蚀的ComeiBunbury大火成岩省的残余。

A total of 29 groups of isotope age data such as Sr-Nd isotope age data and Nd model age data of igneous rocks, including granites, volcanic rocks, dyke swarms, cumulates, and ophiolites, formed in different periods of time are reported in this paper, which show the following two features:(1) igneous rocks including ophiolites formed in this area since 800 Ma BP all have high eNd and low Sri, with most Sri values centered in the range of 0.7045 to 0.7060 and eNd values in the range of 1 to 5, and (2) most of the TDM ages are in the range of 800 to 600 Ma, with only a few at 1000 Ma.

收集了本区不同时期形成的各类火成岩，包括花岗岩、火山岩、岩墙群、堆晶岩、蛇绿岩的Sr－N等30组同位素数据，从中可以看到以下两个特征：①研究区从800Mr以来形成的包括蛇绿岩在内的火成岩都有高εNd低Sri的同位素特征，绝大多数Sri集中在0.7065～0.7060之间，eNd集中在1～5之间。②TDM年龄较多集中在800 ～600 Ma，个别为1000 Ma。

In contrast to the compositional polarity for the arc magmatism, the symmetrical lateral zonation for the rifting magmatism is indicated.

指出大陆裂谷带的火成岩常呈组成对称的水平分带，而不同于弧火成岩的组成极性。

By research for deep faults and igneous rocks related to CO2 gas fields, the author considers that magma is the carrier for CO2 gas migration, while the development of igneous rocks is an important sign of the synchronous fault spatio-temporal activity. The 'migration' is one of the most important elements for mantle source CO2 gas accumulation, which means that there are deep faults connected to the mantle, directly or indirectly, and fault activity must be consistent with CO2 gas migration in space and time.

通过对与CO2气田有关的深大断裂、火成岩进行综合研究认为，岩浆是CO2运移的载体，火成岩的发育则是断裂时空同步活动的重要标志，幔源CO2气的成藏要素最为重要的是&运&，即要有直接或间接与地幔相连的深大断裂，而且，作为一条断裂通道的活动要时空同步。

By slow cooling plutons?- And what is a pluton?

慢慢冷却火成岩-什么是火成岩？

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
