luoxue meaning in Chinese
落雪
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 - 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。 - Xikuangshan type copper ore deposit named those fe - cu deposits hosted in yinmin formation , kunyang group , which located in kunyang rift valley and the edge of southwest yangzi platform . the best example is xikuangshan allotment , luoxue ore area , dongchuan , yunnan . the type deposit spread in south kunyang rift valley , include dongchuan , wuding - luoci , yuanjiang , yimen , huashengping , hongmenchang and so on
稀矿山式铜矿是指赋存在昆阳群因民组地层中的铜铁矿床，其大地构造背景属于元古代裂谷带，大陆裂谷是超大型铜等多金属矿形成和分布的有利环境，在裂谷下部常发育异常地幔和岩浆源，裂谷空间上的多层次性使矿床具有明显垂向分带特征，其演化时间的长期性、脉动性和继承性便于多期成矿作用相互叠加、矿质的高度聚集。
