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

在富來梯,主巖為細粒接觸相的石英閃長巖。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。Glaucophane schist facies
藍閃片巖相Obsidian has been used since ancient days for making some of the oldest cultural artifacts developed by man. it was widely used by the mexicans for making images of their god tezcatlipoca and for polishing mirrors to be used to divine the future. in egypt, masks made of black obsidian have been found
也有可能是全部單色或有條紋或有斑點,最有名的是有彩虹閃光的彩虹黑曜巖rainbow obsidian ,並且有些條文呈橢圓形狀,就形成俗稱的單眼黑曜或者是雙眼黑曜石了,而如果以價格來看,彩虹單眼黑曜及彩虹雙眼黑曜是價格最高的,因為除了產量較為稀少之外,品相也相當的漂亮。A ree partition simulation suggests that the tianzhushan intermediate rocks can be generated by partial melting, in coupling with fractional crystallization, of dioritic gneiss which is similar in chemical compositions to the mafic rocks in the lower crust in north dabie ; partial melting of intermediate grey gneiss which is similar in chemical compositions to the middle crust in north dabie can generate the tianzhushan felsic rocks
