basite 中文意思是什麼

basite 解釋
基性巖類
  1. Alkali basite, which came from upper mantle or lower crust, invaded through those structure, which not only bring cu et al mineralizing elements, but also the most important is that thermal energy. it cycled the formation water ( yinmin fonnation and luoxue formation ), and form alkali - rich, middle - high temperature and salinity fluid mixed with alkali - rich magmatic water. there were high rate of percolation and well voidage in the contact zone between yinmin purple stratum and yinmin rubblerocks, which is in favor of the transposition and mineralization of minerogenetic fluids

    因此,總結東川稀礦山式銅礦成礦模式為沉積( fe 、 cu ) ?熱液疊加( cu )改造:晉寧-澄江期,小江深大斷裂發生走滑運動,在東川礦區造成右行旋扭及其派生構造,形成「 z 」字形落因破碎帶,同時來自深源(下地殼或上地幔)堿基性巖漿侵入,不僅帶來了大量cu等成礦物質,更重要的是提供了熱源,促使地層水(落雪組白雲巖和因民組紫色層)循環,與富堿( na和k )巖漿水混合,形成富堿中高溫高鹽度流體。
  2. D ) the invasion of jinningian - chengjiangian alkali basite were unambiguous, the distribution of those rocks form " z " in shape, which similar with luoyin fracture zone and the distribution of copper deposit. it shows that copper deposits were controlled by discordogenic fault and its derived sub - structure, and there are relationship between copper deposit and jinningian - chengjiangian alkali basite. e ) most of minerogenetic age of copper deposit, which located in kunyang rift valley, belongs to jinningian - chengjiangian ( between 900 - 650ma ), similar with the time limit of breaking - up of rodinia

    東川礦區晉寧-澄江期堿基性巖侵入活動明顯,常作為因民組復雜角礫巖膠結物和巖脈(體)產出,多分佈於深大斷裂及其派生的次級構造附近,明顯受南北向小江深大斷裂走滑運動引起的右行旋扭及其派生構造控制,與「落因破碎帶」和「銅礦分佈」較吻合,均為「 z 」字形。
  3. The following new knowledge are acquired : a ) the cu background of stratum and jinningian alkali basite is abnormal high, which could be liberated from those rocks during alteration. cu et al. minerogenetic elements, which main came from magmatic rock, some from stratum ( yinmin formation and luoxue formation ) and its basement rocks

    礦床中cu等成礦物質來源復雜,以深源為主,部分來源於地層(因民組紫色層和落雪組白雲巖)及基底地層;礦區內的退色蝕變作用可能是混合流體堿質交代改造作用的結果,對銅礦形成影響明顯,是銅礦化的標志; 2
  4. C ) copper ore body surrounded iron ore body ; iron ore were interpenetrated by copper ore stringer vein, which indicated that copper form late than iron. metallogeneti age is 826 230ma, similar with the age of alkali basite and age of other copper deposit in dongchuan ore area, which belong to jinningian

    黃銅礦單礦物的re - os同位素年齡研究表明其成礦年齡為826 230ma ,接近礦區堿基性巖年齡,與昆陽裂谷內其它類型銅礦成礦時代相當,均屬于晉寧?澄江期; 4
