斑岩的

Late Yanshanian, plutonic monzonite granites causes molybdenum and tungsten mineralization .

燕山晚期形成的位于区内东北部的中—深成相二长花岗岩成矿作用主要为斑岩型钨钼矿。

They have A/CNK values of 0.9～1.2, suggesting aluminum saturation or ersaturation, and are enriched in LREE and LILEs and depleted in HFSEs. Their δEu values are 0.11～0.32, evidently indicating plagioclase fractional crystallization.(87Sr/86Sr)i ratios and εNdvalues are 0.707?9～0.716?1 and -6.90～-7.70 for volcanic rocks, and 0.7086～0.7098 and -7.10～-7.68 for quartz syenitic porphyrite, respectively, implying that all the igneous rocks from the Yandang Mountain were evolutional products of co-magmas, and derived mainly from the crust, mixed however with mantle components.

岩石富集轻稀土元素和大离子亲石元素，相对亏损高场强元素；δEu值为0.11～0.32，表明岩浆经历了以斜长石为主的强烈结晶分异作用；火山岩(87Sr/86Sr)i为0.707 9～0.716 1，εNd为-6.90～-7.70，中央侵入体石英正长斑岩(87Sr/86Sr)i为0.708 6～0.709 8，εNd为-7.10～-7.68，表明它们是同源岩浆不同阶段分异演化的产物，物质来源主要为陆壳，但也有地幔物质参与。

It has been proved that a large amount of reduced sulfur is necessary for the formation of porphyry copper deposit .

第二期富含还原硫流体的加入，是西范坪斑岩铜矿床形成的重要控制因素之一。

The Beiya gold deposit with a large-sized prospective reserves is a polygenetic deposit related to alkaline syenite porphyry.

北衙金矿床是与碱性正长斑岩有关的具大型资源远景的一个多成因矿床。

Typically occur within diamondiferous kimberlites and are used as mineralogic tracers in the search for diamond deposits by prospectors.

在这种火山岩浆的管道之一，通常是两种类型的特点，成为酷火成岩要么称为金伯利或者钾镁煌斑岩。

It led to his famous discussion of the "lamprophyre concept".

这导致了他的关于&煌斑岩概念&的著名讨论。

Comparative studies show that during the alteration of lamprophyre, K20, TiO2 and P205 were rather stable ,whereas Si,Ca Mg and Fe were evidently taken out or brought in.

对比研究表明，区内煌斑岩蚀变过程中K2O、TiO2、P2O5等的含量较稳定，Si、Ca、Mg、Fe等元素有明显的带入带出。

Veined,stockwork and alteration-sheathed gold ores have been found in the area, belonging to four genetic types: the volcanic hydrothermal ores related to early-middle Carboniferous volcanism; subvolcanic hydrothermal ores related to intermediate-acidic porphyry intrusions; hydrothermal ores to the granitic intrusion and dynamo- hydrothermal ores related to regional dynamic metamorphism along the faults .

矿床成因类型有4种：一为火山热液型，其成因与区内早-中石炭世火山作用有关；二为潜火山热液型，与中酸性斑岩体侵位有关；三为岩浆热液型，与花岗质岩浆的侵位有关；四为动力变质热液型，沿断裂带分布于蚀变玄武岩中，系区域动力变质作用的产物。

The Shengmikeng vein-type lead-zinc deposit is located in Huanggangshan volcano-tectonic depression of the Mesozoic volcanic belt in Northern Wuyi.The ore featured by veinlets and disseminations is hosted both inside the fault zone in the upper Jurassic Ehuling ignimbrite and the potassic trachyte porphyry.

摘 要：生米坑铅锌矿床位于北武夷中生代火山岩带的黄岗山火山盆地内，已知铅锌矿体呈脉状产于侏罗系上统鹅湖岭组流纹质熔结凝灰岩的断裂内，或呈细脉——浸染状分布于钾质粗面斑岩内，发育钾长石化、绿泥石化、硅化等蚀变。

Those younger porphyries were much fresh and were looking elegant!

这些年轻的斑岩明显，并正在寻找新的优雅！

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
