岩浆

The crystallization temperature, pressure and depth of clinopyroxene phenocrysts from the picrite and basalt were calculated on the basis of the clinopyroxene-melt equilibrium principle.

根据单斜辉石-熔体平衡原理计算了苦橄岩中单斜辉石斑晶形成的温度和压力，其变化范围主要集中在1350～1387℃和16.6～21.3kPa，相应的深度为55～70km，大致代表了苦橄岩岩浆房的深度。

The pillow lava was formed as a result of condensation of magma in lake, when it effused again during the intermittent of volcanic activity in the second subcycle.

其是在第二亚旋回火山活动间歇期，岩浆再次溢出，涌流进水体里冷凝而成为陆相环境产物，与海相玄武质枕状熔岩明显不同。

The pillow lava, with affinity of MORB, plots in the field of MORB and IAT, suggesting that the Yushigou ophiolite formed in a tectonic setting like the Middle Ocean Ridge and then were changed by volcanic arc magmatism.

地幔橄榄岩主要是方辉橄榄岩，其主要氧化物成分较为单一，具LREE富集、Eu亏损的U形REE配分模式，亏损强不相容元素；枕状熔岩具典型MORB特征，在构造判别图解上位于MORB和IAT区域，指示蛇绿岩可能形成于类似于洋中脊的构造环境，并受到火山弧岩浆作用的影响。

And the late Triassic bimodal association reflects the characteristics of intracontinental rift setting, the early Jurassic Raohe ultramafic - mafic rock - pillow lava association represent the environmental characteristics of oceanic island, magmatic arc association represent the characteristics of island arc and active continental margin with the background of the plate subduction, middle Jurassic syn-orogenic granodiorite-granite association reflects characteristics of matching and orogensis after continental accretion.

其中晚三叠世双峰式组合反映了板内裂谷成因特征，早侏罗世饶河超镁铁质-镁铁质岩-枕状熔岩组合代表了洋岛环境特征，岩浆弧火成岩组合代表了板块俯冲背景下岛弧和活动大陆边缘特征，中侏罗世同造山花岗闪长岩-二长花岗岩组合反映了陆缘增生后拼贴造山的成因特点，它们总体上代表了由被动陆缘裂向活动陆缘转化并最终发生陆缘增生带拼贴造山的一个演化过程，其间伴随有被动陆缘深海盆地沉积、活动陆缘弧后前陆盆地沉积和陆相类磨拉石建造

It reveals that leucogranitic magma activity at least lasts to Pliocene Epoch in central segment of Higher Himalayan crust.

在聂拉木地区获得了6.23Ma浅色体形成年龄(这是目前在高喜马拉雅中段获得的最年轻的花岗岩浆活动的年龄资料)，标志着该地区的岩浆活动至少持续到上新世。

Such sedimentation followed a 20~25 Ma-long period of Tiaojishan/Lanqi volcanism and was accompanied by plutonic emplacement (ca.158~141 Ma) in some Yanshan areas.

土城子组/后城组的沉积是紧随着在燕山部分地区发生的，持续了20~25Ma的髫髻山组/蓝旗组火山及岩浆活动。

Magmatism in the form of volcanism and plutonism is predominant in the diwa maximummobility period which results in thick volcanic rock and all big intrusive bodies in the area.

岩浆作用(包括火山作用和侵入作用)在北京西山地洼激烈期中有强烈的表现，形成区内巨厚的火山堆积和大规模的侵入体。

The Dabie Mountains are unique among ultrahigh pressure metamorphic terranes in having the most profound post collisional plutonism The Mesozoic shoshonitic and calc alkaline intrusive rocks can be divided into three groups with different isotopic ages, rock assemblages and chemical features Group I consists of late Triassic (~ 210 Ma) mafic monzodiorites It could have been generated by partial melting of enriched subcontinental lithosphere mantle due to slab breakoff Group II consists ma...

第 I组，主要由晚三叠世（约210 Ma）二长闪长岩辉长岩体组成，它可能是在板片断离过程中富集的大陆岩石圈地幔部分熔融的产物；第I I组，由中侏罗世－早白垩世（160～120 Ma）的角闪石英二长岩、黑云母二长花岗岩和正长花岗岩组成，主要是由幔源岩浆的分离结晶与地壳混染共同作用的产物；第II I组，以白垩纪（125～95 Ma）的花岗岩和花岗斑岩为代表，是在热穹窿作用过程中大别杂岩深熔作用和高度演化的产物。

The geochemical characteristics of basic to intermediate-basic igneous rocks indicate that they belong to a tholeiite suite. Their chondrite-normalized REE patterns are of nearly flat and slightly LREE-enriched type, and their primitive mantle-normalized and MORB-normalized trace element spidergrams are generally similar; the LILEs Cs, Ba, Sr, Th and U are enriched, while Rb and K and the HFSEs Nb, P, Zr, Sm, Ti and Y are depleted. All these show comagmatic evolutionary and genetic characteristics.

基性—中基性岩浆岩的地球化学特征表明其属于拉斑玄武岩系列，稀土元素分布型式呈REE近平坦型—LREE轻微富集型，微量元素原始地幔标准化的蛛网图和MORB标准化蛛网图上的分布型式总体很相似，富集大离子亲石元素Cs，Ba，Sr，Th，U而相对亏损Rb，K和高场强元素Nb，P，Zr， Sm，Ti和Y，显示同源岩浆演化成因特征。

The posttraumatic hydrothermal solution is the principal source of ore-forming fluid.

中文摘要：红石地区叶家小湾金矿形成于燕山晚期，成矿流体主要来自岩浆期后热液。
