中文拼音 [jiǎoshǎnyánxiāng]
角閃巖相
英文
amphibolite facies-
Hornblende bearing varieties bridge the gap over to amphibolites which are in bands and dikes.
含角閃石的變種填補了帶狀和脈狀角閃巖的中間相。Lots of information suggest that the metamorphism process of this area are from granulite facies to amphibolite facies and the retrograded metamorphic path is basically a cw nearly isothermal decompressional evolvement trend
各種信息表明本區的變質作用是由麻粒巖相退變到角閃巖相。退變質軌跡基本上是一個順時針近等溫減壓型演化趨勢。Based on the 1 : 50000 regional geological survey, the sertengshan rock group is revised, involving the schist and marble of low - amphibolite to high - greenschist facies, which are distributed in middle and west inner mongolia
摘要根據近年完成的1 : 5萬區域地質調查成果及綜合研究,將分佈於內蒙古中部色爾騰山、大青山、西部烏拉特后旗以及阿拉坦敖包、疊布斯格等地的低角閃巖相高綠片巖相的片巖、大理巖系釐定為色爾騰山巖群。All these rocks aforementioned are mainly parametamorphic rocks. milan, kaqiang and alamasi group underwent high - grade metamorphism of amphibolite facies, together with weak migmatism. they share the same geochemistry and total ree and many other chracters
二者主要為副變質巖石,米蘭巖群和卡羌巖群、阿拉瑪斯巖群變質較深為角閃巖相,普遍弱混合巖化,它們具有非常相似的地球化學特徵,稀土元素總量及其它特點一致或相近。Based on the studies of petrotexture, structural deformation and the relevant metamorphism, this paper indicates that this peridotite massif is the product of ultramafic magma cumulated at the crust - mantle transtion zone and has undergone the early stage of plastic deformation under the condition of granulite facies ( 800 ) and late ductile shearing at amphibolite and greenschist facies in relevance to uplifting
本文通過巖體的結構、構造變形及相應的變質作用研究,提出了該橄欖巖體是由超基性巖漿在殼幔過渡帶結晶而成,並經歷了與圍巖一致的麻粒巖相( 800 )條件下的早期塑性變形以及角閃巖相和綠片巖相退化變質條件下與逆沖上升有關的韌性剪切變形。The qiongzhong and danxian batholiths, as the largest early mesozoic syntectonic granite intrusions in hainan island, are mainly composed of porphyritic biotite two - feldspars granitoids, in which alkali - feldspar phenocrysts and dark minerals are foliated mostly in we - direction. the granites are of metaluminous i - type. major and trace elements show co - variations with sio2, suggesting the fractional crystallization of plagioclase, hornblende, apatite and ti - fe oxides in the evolution of the granites
花崗巖的主量元素和部分微量元素成分與sio _ 2呈良好的相關關系,顯示出明顯的斜長石、角閃石、磷灰石和ti - fe氧化物等的分離結晶作用,總體上它們與大陸島弧花崗巖的微量元素豐度和分佈特徵相似,系統地虧損ba 、 nb 、 sr 、 p和ti等元素。Greenschist facies, low green schist facies and brittle shear deformation facies. the attitude of different structural element of the yagan mcc are keeping coordination. analysis of kinematics demonstrates the sse - directed shearing - off of the hanging wall relative to the footwall along the penetrative mylonitic lineation
其變形相由變質核中心到上盤巖系(由深至淺)依次為高角閃巖相? ?綠片巖相? ?低綠片巖相? ?脆性剪切變形相,顯示亞干核雜巖由中心向邊部變形層次遞減的特點。分享友人
