中文拼音 [huāgǎngbiànjīng]
花崗變晶
英文
granoblastic-
Detail mapping shows that the yagan mcc consists of crystallized metamorphic core ( low plate ), detachment zone and upper plate. the metamorphic core consists of can be further subdivided into two level parts low - level high metamorphic and upper - level shallow metamorphic structural slice and between them there exists a ductile shear zone. thus the whole texture of the mcc is characterized by " three layers and tow zones " this reveals a process of extensional uplift of poly - level slices by poly ductile shear zones, a characteristics of poly - level extensional structural systems. the deformational environments change vertically in a sequence of high amphibolite facies
亞干變質核雜巖由下盤結晶巖系變質核、拆離帶和上盤巖系構成,其中,變質核由四個單位及許多花崗巖體(脈)組成,可進一步分為中深和中淺變質兩個構造單位(巖片) ,之間發育次級韌性拆離帶(花崗質糜棱巖帶) ,加上上盤總體構成「三層兩帶」的結構特點。And apatite. by these analyses and comparison with general granite both in china and the world and with the granite in other au or cu belt in china, the characteristics of the granite in this area are concluded as follows. it belongs to magnetite - i or syntectic granite and has crust - mantle mixed characteristics ; it was formed mainly by crystallization differentiation of melting magma and multiphase varied intrusion ; the degree of differentiation evolvement is not high ; the granite and its enclaves p. re congenetic ; the range of temperature is about 500 - 700, the range of pressure is about 2. 50 gpa - 4. 35 gpa, and the range of oxygen fugacity ( lg fo2 ) is - 15. 53 - - 14. 00 ; most granite bodies formed before the collision of plates, and few formed after the collision of plates
通過對測試數據的分析與綜合研究,並同中國和世界一般花崗巖類以及中國主要金、銅成礦巖體的花崗巖類進行對比,得出本區花崗巖類巖石具有以下特徵:屬磁鐵礦-型或同熔型花崗巖,其巖漿物質具殼幔混源特徵:主要由熔融態巖漿經結晶分異作用,通過多期變速上侵而形成;其分異演化程度較低;寄主巖基和包體具有同源性;巖石的形成溫度范圍約為500 - 700 ,壓力大約為2 . 50gpa - 4 . 35gpa ,氧逸度值1gfo _ 2為- 15 . 53 ? 14 . 00 ;該巖帶主要形成於板塊碰撞前消減的活動板塊邊緣期,為燕山至喜馬拉雅早期的大陸邊緣火山弧環境的產物。C : is used for purifying water quality to make the tourmaline powder tourmaline ceramsite, is used for purifying in the ore container, can remove the chlorine of the running water, thus change the acidity of water
電氣石多與氣成作用有關,一般產于花崗偉晶巖中,也可產于交代作用形成的變質巖中。具壓電性的晶體可用於無線電工業,色澤鮮艷者可作寶石,在中國稱為碧璽。According to the constructive principles of these diagrams, the following aspects must be thought carefully : the rock types to be studied must be the same or nearly the same as those that can be discriminated by the diagram ; to avoid mixed or incorrect signals that could be produced, two or more such diagrams shall have to be jointly used ; for special rock types, such as a - type granites or potassic igneous rocks, special discriminative diagrams have to be determined and selected respectively ; the samples to be studied can not be altered ; in general, the diagrams must be used carefully with archean samples ; the petrotectonic assemblage or an expert system are recommended to be used together with the discrimination diagrams
強調指出:所採集的樣品必須新鮮(無蝕變或極弱蝕變) 、非堆晶的巖石;選擇的判別圖解必須與判別的巖石類型相一致,即對花崗巖類要用花崗巖的判別圖解,不能用玄武巖的判別圖解;對特殊類型巖石要選擇專門用於該類型巖石的判別圖解,如堿性花崗巖,鉀質火成巖;要應用多種圖解綜合判斷;不能用單個樣品,而應作多個樣品分析;要注意所選擇判別圖解的特別說明等。分享友人
