例句與用法

1. 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(zhì)來源復(fù)雜，以深源為主，部分來源于地層(因民組紫色層和落雪組白云巖)及基底地層；礦區(qū)內(nèi)的退色蝕變作用可能是混合流體堿質(zhì)交代改造作用的結(jié)果，對(duì)銅礦形成影響明顯，是銅礦化的標(biāo)志； 2
2. 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(qū)堿基性巖年齡，與昆陽裂谷內(nèi)其它類型銅礦成礦時(shí)代相當(dāng)，均屬于晉寧?澄江期； 4
3. 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(jié)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(fā)生走滑運(yùn)動(dòng)，在東川礦區(qū)造成右行旋扭及其派生構(gòu)造，形成“ z ”字形落因破碎帶，同時(shí)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(zhì)，更重要的是提供了熱源，促使地層水(落雪組白云巖和因民組紫色層)循環(huán)，與富堿( na和k )巖漿水混合，形成富堿中高溫高鹽度流體。
4. 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(qū)晉寧-澄江期堿基性巖侵入活動(dòng)明顯，常作為因民組復(fù)雜角礫巖膠結(jié)物和巖脈(體)產(chǎn)出，多分布于深大斷裂及其派生的次級(jí)構(gòu)造附近，明顯受南北向小江深大斷裂走滑運(yùn)動(dòng)引起的右行旋扭及其派生構(gòu)造控制，與“落因破碎帶”和“銅礦分布”較吻合，均為“ z ”字形。
