英云闪长岩

埃达克岩（adakite）是一种特殊的岛弧安山岩、英安岩、流纹岩（以英安岩最常见）或英云闪长岩和奥长花岗岩。

Adakite is a special kind of island arc andesite , dacite and rhyolite ( mainly dacite ) or tonalite and trondhjemite .

英云闪长岩岩性不均匀，而300m以下似斑状二长花岗岩的岩石均匀性较好，其单轴抗压强度和弹性模量较高。

Rock near the ground and tonalite is not uniform , and the granite 300 meters below the ground is uniform with uniaxial compression strength and Young ′ s module .

In this paper the authors discuss their characteristics in terms of geology , petrology , petrochemistry , REE and U Pb isotopic age .

经岩石化学研究，组成该岩群的片麻岩具英云闪长岩-奥长花岗岩-花岗闪长岩（TTG岩系）组合特征。

Petrochemical studies show the gneiss has the combined characteristics of tonalite-diorite , trondhjemite and granodiorite ( TTG rock formation ) .

它还受到多期构造变形，平卧褶皱，韧性剪切带和推覆构造均有广泛发育。绿岩中伴生的花岗质岩石，主要为TTG岩系的奥长花岗岩英云闪长岩花岗闪岩系列。

They underwent polyphase structural deformation , giving rise to well developed recumbent folds , ductile shear zones and nappe structures .

此外，侵入泰山群的花岗闪长岩，其全岩Rb-Sr等时线年龄为2586Ma，英云闪长岩锆石U-Pb年龄为2628Ma。

Besides , the granodiorite intruding the Taishan Group has a whole-rock Rb-Sr isochron age of 2586 Ma and tonalite has a zircon U-Pb age of 2628 Ma .

岩体主要岩石类型为花岗闪长岩及英云闪长岩，以发育富铁黑云母、属过铝质岩石为特征。

The rock body is composed of mainly granodiorite and quartz-mica diorite .

Guangtoushan granitoids are located in the north of Mianlue suture zone , which consist of tonalites and monzogranites .

变石英闪长岩和变英云闪长岩的锆石类型有二个主型和七个亚型。

The zircons from the meta-quartz diorite and meta-quartz-micadiorite in the area have two main types and seven subtypes , separately .

英云闪长岩在胶东地区是首次确定，对于该区基础地质研究具有重要意义。

The tonalites are first identified in eastern Shandong , which is of vital significance to the study of basic geology in the area .

因此，花岗岩类是深成岩的一个大类，包括象花岗闪长岩、二长花岗岩、正长花岗岩、英云闪长岩等这样的岩石。

Therefore , the granitoid is a big group of plutonic rocks including such as granodiorite , monzonite , syenogranite , tonalite , and so on .
