花岗片麻岩

In addition, the porphyritic allanite- formed by magmatic crystallization was found in the granitic gneisses, it not only shows that the granitic gneisses were metamorphized from magmatic rocks, but also shows that the degree of the metamorphism undergoen was not very intense.

另外在花岗片麻岩中发现有岩浆结晶成因型褐帘石斑晶的残留，这一方面说明这套花岗片麻岩的原岩是种岩浆岩，同时说明它们所经历过的变质作用程度不可能很强。

Based on the study of the ages, mineral chemical, petrochemical and isotopic geochemical characteristics of granitic gneisses in Shuihou area of southern Dabie mountain, combining with the study of comparing these gneisses with the orthogneisses in northern Dabie mountain, it can be fould that there were clearly differentices between the granitic gneisses in southern Dabie and northern Dabie mountain.

论文通过对该造山带南大别水吼地区花岗片麻岩的时代、矿物化学、岩石化学及同位素地球化学特征的综合研究，并通过与北大别正片麻岩的对比研究，进一步证实南、北大别的花岗片麻岩套具有明显的差别。

The rocks were mainly granite and granite gneiss.

岩石主要是花岗岩和花岗片麻岩。

It is confirmed that the Luzhenguang complex is composed mainly of meta-basic rocks, granitic gneisses and meta-sediments.

确定了卢镇关杂岩主要由变质基性岩、花岗片麻岩和被它们侵入的变质沉积岩组成。

In mineral chemistry, the plagioclase in the granitic gneisses from southern Dabie mountain was high riching in Na, and the biotite and hornblende were characterized by riching in Fe, showing clearly the continental crust source.

在矿物化学成分上，南大别花岗片麻岩中的斜长石高度富钠，黑云母和角闪石总体以富铁为特征，明显具有大陆地壳源的性质。

Resulting in f orming some migmatite and granitic gneiss.

同时形成一些混合岩和花岗片麻岩。

The granitic gneisses from the southern Dabie mountain with peculiar mineral assemblage, were characterized by containing riching-Mn garnet, phengite, sphene, quartz, clearly differ from UHP paragneiss.

南大别花岗片麻岩中具有独特的矿物组合，以含富Mn石榴石、多硅白云母、榍石、石英为特征而明显不同于超高压副片麻岩。

To No. 20 are respectively black mudstone, black mudstone ( Caitun mining area of Benxi Basin,Paleozoic), dark grey gangue (Caitun mining area of Benxi Basin, Paleozoic), brown shale(Caitun mining area of Benxi Basin, Paleozoic), brown grey shale(The West Opencut Coal Mine of Fushun Basin, Cenozoic), grey silty mudstone(Haizhou Opencut Coal Mine of Fuxin Basin, Mesozoic), black grey gangue(Haizhou Opencut Coal Mine of Fuxin Basin, Mesozoic), grey yellow clay(Jianping County, Chaoyang City, its era to be determined), grey silicon slate( Qianshan Mountain of Anshan City, pre-Paleozoic), grey phyllite(Qianshan Mountain of Anshan City, pre-Paleozoic), granite-gneiss(Qianshan Mountain of Anshan City, pre-Paleozoic), granite(Mount Yiwulu, its era to be determined), diorite(Mount Yiwulu, its era to be determined), black basalt(The West Opencut Coal Mine of Fushun Basin, Cenozoic), dark purple andesite( Mount Guiyunhua of Zhuanghe City, Mesozoic), fragment of brick-tile-pottery-porcelain( from the building site of Panjin City), coal cinder( from the boiler room of Heji Road of Panjin City), cement( from the building site of Panjin City) and slag (from Bohai Stockroom of Liaohe Oilfield produced in Anshan City).

2-20号样品分别是黑色泥岩、黑色泥岩、深灰色煤矸石、褐色页岩、褐灰色油页岩、灰色粉砂质泥岩(阜新海州露天矿、中生代)、黑灰色煤矸石(阜新海州露天矿、中生代)、灰黄色膨润土、灰色硅质板岩、灰色千枚岩、花岗片麻岩、花岗岩、闪长岩、黑色玄武岩、暗紫色安山岩、砖瓦陶瓷碎片、粉煤灰、水泥、矿渣(鞍山产、取自辽河油田渤海库)，这19个样品用来代表工业、采矿、冶炼、建筑等行业产生的固体废弃物。

During the subduction and collision of Yangtze and Sino-Korean craton in Triassic period, they all subduced into mantle depth, due to the granite was relative poor in water and denser than sedimentary rocks, the kinetics rate of metamorphism of granite was much more slow than that of sedimentary and mafic volcanic rocks.

即在扬子板块与中朝板块三叠纪俯冲—碰撞过程中他们一起进入到地幔深度的超高压环境，但由于花岗片麻岩的原岩相对于副片麻岩的原岩明显贫水且结构致密，其中发生变质作用的动力学速度明显慢于沉积岩或基性火山岩中的动力学速度。

Thise granitic gneisses also lack those typical texture that can reflect had undergone UHP metamorphism which are common in paragneisses ,such as biotite reaction rim of phengite.

同时花岗片麻岩中缺少副片麻岩中常见的一些能反映经历过超高压变质作用的特征性结构，如多硅白云母周围的黑云母反应边结构。
