basite meaning in Chinese
基性岩类
Examples
- 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
矿床中cu等成矿物质来源复杂,以深源为主,部分来源于地层(因民组紫色层和落雪组白云岩)及基底地层;矿区内的退色蚀变作用可能是混合流体碱质交代改造作用的结果,对铜矿形成影响明显,是铜矿化的标志; 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
黄铜矿单矿物的re - os同位素年龄研究表明其成矿年龄为826 230ma ,接近矿区碱基性岩年龄,与昆阳裂谷内其它类型铜矿成矿时代相当,均属于晋宁?澄江期; 4 - 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,总结东川稀矿山式铜矿成矿模式为沉积( fe 、 cu ) ?热液叠加( cu )改造:晋宁-澄江期,小江深大断裂发生走滑运动,在东川矿区造成右行旋扭及其派生构造,形成“ z ”字形落因破碎带,同时来自深源(下地壳或上地幔)碱基性岩浆侵入,不仅带来了大量cu等成矿物质,更重要的是提供了热源,促使地层水(落雪组白云岩和因民组紫色层)循环,与富碱( na和k )岩浆水混合,形成富碱中高温高盐度流体。 - 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
东川矿区晋宁-澄江期碱基性岩侵入活动明显,常作为因民组复杂角砾岩胶结物和岩脉(体)产出,多分布于深大断裂及其派生的次级构造附近,明显受南北向小江深大断裂走滑运动引起的右行旋扭及其派生构造控制,与“落因破碎带”和“铜矿分布”较吻合,均为“ z ”字形。
