查询词典 dike rock

So, here is a good example of a rock, a sedimentary rock but with a white dike.

The ophiolites can be divided into two groups at least; one lies in the Kuhai complex and intersected by Caledonian island granite, which may be attributed to Caledonian or pre-Caledonian ophiolite association; the other lies in the Early Permian — Early Triassic Ma'erzheng Fm. of Buqingshan Gr., including ultramafic rock, basalt, diabase dike and pelagic siliceous-argillaceous association, and Early Permian radiolarian are found in the silicates, which reflect that the time is Hercynian.

其中蛇绿岩组合至少可分出两套，其一就位于变质的苦海杂岩中，被加里东期岛弧型花岗岩侵入切割，可能属加里东期或前加里东期的蛇绿岩组合；其二就位于早二叠世—早三叠世布青山群马尔争组中，包括超镁铁质岩、玄武岩、辉绿岩墙及远洋硅泥质岩组合，其中硅质岩中发现有早二叠世放射虫，说明其形成于海西期。

In meymechite dike and phogopite-plagioclase peridotite dike, MgO content respectively is 28.86%～ 32.78% and 27.28%～ 34.99%., they belong to the ferrguinous ultrabasic rock .

玻质纯橄岩脉和金云斜长橄榄岩脉，它们的MgO含量分别为28.86％～32.78％和27.28％～34.99％，属于铁质超基性岩。

Dioritic enclaves were discovered by the authors in thesubvolcanic rock dike of the northern part of the large collapse volcanic basin in Xiangshan, Jiangxi Province. These enclaves have a typical back vein and a quenched margin,and contain a large number of acicular apatites.

在江西相山大型塌陷式火山盆地北部的潜火山岩岩墙中，笔者发现了闪长质的岩石包体，这种包体具典型的反向脉及淬冷边，且淬冷边内含有大量针状磷灰石。

The Permian dike rock is great development at Kuruktag Region, their rock association is diabase-tjositeplagiophyrite-granite-porphyry, among them, diabse is the most main rock type.

库鲁克塔格地区二叠纪脉岩群非常发育，主要岩石类型是辉绿岩，并有少量的斜闪煌斑岩、斜长玢岩和花岗斑岩。

The SiO2 content of the dike swarms varies from 50.22% to 61.10% and they are basic-intermediate rock series, mainly basic. The Al2O3 content is generally higher than 15% and they are high aluminum basaltic rocks. The lower magnesium index (Mg#=42.77~62.28) and TiO2 content (0.97~2.41%) illuminate that they suffered magnesium-iron minerals' fractional crystallization and that they did not crystallize from original basaltic magma. The values of Na2O/K2O are all above 1, indicating lower K character. Chemically discriminated, these dike swarms are sub-alkaline rock series.

岩墙群的SiO2含量为50.22~61.10%，属于基性和中基性岩类，以基性为主；它们的A12O3含量普遍高于15%，属高铝玄武岩类；具有较低的镁指数（Mg#=42.77~62.28）及TiO2含量（0.97~2.41%），说明它们经历了镁铁质矿物的结晶分异作用，也指示它们不是由原始玄武岩浆结晶；Na2O/K2O都大于1，显示出低钾的特点；岩石化学判别，岩墙群岩石属亚碱性系列。

The analysis of lamprophyrespetrology chemistry reveals that it is a series of high potassium- potassium dike rock,it is abandunt in alkali(K2O,Na2O)and has a large reducing capacity.The diagrams of the major-element variation shows that the geochemical compositions-variations of the major oxides have vague general rules of homologous magmatic fractional-crystallization.the pearce diagram of trace elements shows it intensively enriched in LILE,intensively depleted in coherence elements(such as CrNi.et al).

煌斑岩的岩石化学分析表明，乳山地区与金矿成矿相伴生的煌斑岩为高钾质-钾质的碱性脉岩系，富碱(K_2O、Na_2O)，具较强的还原能力(FeO含量均远高于Fe_2O_3含量)，在哈克图解上，主要氧化物的变异规律表现出岩浆分离结晶演化的特点；微量元素的Pearce图呈现强烈的富集LILE，强烈亏损过渡族元素，稀土元素呈向右倾斜的轻稀土富集配分模式，在有关源区性质判别的图解(Cr-Ce／Sr图解和Ce／Yb-Ta／Yb比值图解)上均显示富集地幔源区的性质。

We divide bedrock rock types in the middle and late Proterozonic Era as well as the Archaean Era into three types ,which are metamorphic rock ,deposition rock and the igneous dike.

将西部低潜山带中晚元古代和太古宙基岩岩石类型划分为变质岩、沉积岩和火成岩脉三大类。
