This paper provides detailed petrographic,mineralogic and mineral-chemical data of the segregation with various forms in kamafugites from Western Qinling,Gansu Province,and probes into the nature of these segregations,the composition of the mantle fluid and generating mechanism of these segregations.
提供了甘肃西秦岭新生代钾霞橄黄长岩中各种形态分凝体详细的岩相学、矿物学和矿物化学的资料,对分凝体的性质、深部地幔流体的成分及成因机制进行了讨论。
The kamafugite is a rare type of ultra-potassic rocks, and a rock series contained generally that rock types of alnoite,olivine-melilitite,mafurite,katungite and wugantite and so on.
钾霞橄黄长岩是一种非常稀少的超钾质火山岩,也是一个岩石系列,包括黄长煌斑岩、橄榄石黄长岩、白橄黄长岩、橄辉钾霞岩和乌干达岩等多种岩石类型。
Kamafugite is an ultra potassic volcanic rock occurred in oceanic and/or continental settings, especially in continental rift.
钾霞橄黄长岩是一种产于大洋和 /或大陆环境 ,尤以大陆裂谷最为多见的超钾质火山岩 ,也是世界上出露最少的火成岩之一 ,目前世界只有少数几个国家和地区有这类岩石的报道。
