granitiform

Based on the analysis of thermal contact metamorphic aureoles , granitoid interior structure , quartz axis fabric and strain characters in the different rock unites of yuanshishan granitoid and its wall rocks , the emplacement mechanism of yanshishan granitoid was studied . the magmatic explictite dynamic was advanced in light of regional stress and magma dynamic research . those conclusion was synthesized to ascertain the emplacement mechanism - granitic magma ascended in dikes with the minimum critical width of the magma ascending channels about 2 . 213 . 88m and located in the core of yindianshan dome with the passive style of dyke explictite ; the later unite is a kind of multiple emplacement mechanism with the character of active emplacement of ballooning 同時運用巖漿動力學原理從另一個角度探討其侵位驅動力。綜上指出:經分凝后的活動性巖漿在深部側向擠壓和浮力的聯合驅動下,沿深大斷裂以最小臨界寬度為2 . 213 . 88m的裂隙脈動上侵,整體以巖墻擴展的方式被動定位于銀殿山穹窿的核部,但后期屋面前單元具有主動侵位的特點應為一種復合定位機制。

Based on the study of geologic characteristics , such as mineralogic assembladge , structural and textural features of granite of guidong granitic massif , and by using petrochemical , trace - element and isotopic data , and some petrochemical , trace - element and isotopic diagrams widely applied to the identification of geo tectonic environments , authors recognize that guidong granitic massif was emplaced in post - orogenic collision environment 摘要本文在研究貴東花崗巖巖體巖石礦物組合、結構構造等地質特徵的基礎上,運用花崗巖的巖石化學、微量元素和同位素等分析數據,采用目前廣泛應用的幾種巖石化學圖解、微量元素和同位素圖解等方法,判別了貴東巖體形成的構造環境?造山帶后碰撞型。

Cl , s , f , tongchang porphyry copper deposit and the dajishan tungsten deposit are selected as the studying objectives , detailed investigations have been conducted into the geological and geochemical characteristics of the granitic rock , biotite , trace element and ree geochemistry , fluid inclusion geochemistry and the partitioning coefficients of the f , cl , cu , w . based on these data , the following conclusions are drawn : ( 1 ) fluorine can reduce the viscosity and density of magma , temperature of solide - liquidus line and change the melt frame , but cl has little effect on the melt 主要的認識如下: ( 1 ) f在花崗質巖漿中,可以降低巖漿的粘度、密度、固液相線溫度、改變熔體結構,而cl對熔體結構沒有多大的影響。 f在流體?花崗質熔體相間,絕大多數配分系數小于1 . 0 ,趨向于熔體相中配分, d _ f隨體系中f濃度的升高而增加。

The lower paleozoic strata in the south kunlun massif are kulafuhe group of cambbrian - ordovician . they consists of metamorphic detrital rocks , limestone , magnetite - bearing basalt , quartzite ( meta - silicalite ) , which suggests that they might form at active continent margin . the geochemical characteristics of volcanic and detrital rocks do indicate that they might form at an active marginal environment such as island arc etc . associated with the qimanyuter ophiolite suit , there are lots of early paleozoic granitic plutons 在昆南地塊上的早古生代地層為寒武?奧陶系庫拉甫河巖群,由變碎屑巖、灰巖、含磁鐵礦玄武巖、石英巖(變硅質巖)等組成,顯示其比昆北地塊有較大的活動性,火山巖和碎屑巖的巖石地球化學特征也反映為島弧及活動邊緣環境。

It is believed that the distribution of gold deposits in fujian is controlled by regional deep - seated structure and precambrian volcanic flysch formation containing charcoal is main gold source rock . the accumulation of gold is closely related with yanshan granitic magma intrusion 金礦空間分布受一定的區域深部構造單元所制約,前寒武系富含炭質的火山復理石建造是福建省金礦的主要礦源巖,金的富集成礦與燕山期花崗巖類巖漿侵入作用密切相關。

According to the classification principles of lithological lineage units , the granitic rocks may be divided ( in descending order ) into zhongguanyingzi ( including xiyao and erdaogou units ) and yushulinzi ( including litaizi , nianpanshan and aobaoshan units ) super - units 按巖石譜系單位劃分原則,由早到晚劃分為中官營子和榆樹林子兩個超單元,前者由西窯單元、二道溝單元組成,后者由李臺子、碾盤山和敖包山單元組成。

Thisrough terrain , with its mainly granitic ground that is susceptible to the lossof topsoil nutrients , created acute challenges for reforestation , which only could be overcome with much hard work , dedicated effort and wise planning 因此,必須以加倍的努力和熱誠,以及明智的規劃,方能排除萬難,重植綠蔭。事實上,不論在香港每一角落,重新植林的任務俱艱巨無比。
