| 摘 要： | 六万山花岗岩体形成于早三叠世,存在多个岩浆活动序次,其岩性主要为含堇青石的二长花岗岩.该类花岗岩富含过铝质矿物,高A/CNK,SiO 2、K2 O、TiO 2、Al2 O 3、MgO、FeO含量较高,Fe2 O 3、Na2 O、P2 O 5含量较低.基于各类化学图解,并结合区域地质背景,表明该岩体是在同碰撞造山环境下形成的,地幔为该岩体形成提供了热源,还可能为其提供了一部分物源.

Lithogeochemical characteristics and genesis of granite bodies in Liuwanshan of Guangxi |
| |
| Abstract: | Liuwanshan granite bodies are formed in early Triassic epoch and occur in several magmatic activity series.In terms of lithology,the granite is a kind of cordierite granite which contains iolite.This kind of granite containsrich peraluminous minerals,and is enriched with SiO 2 ,K2 O,TiO 2 ,Al2 O 3 ,MgO,FeO and A/CNK,and is depleted in Fe2 O 3 ,Na2 O and P2 O 5 .Based on various geochemical plots and the regional geo-logical settings,the results indicated that the earth mantle provided the thermal source and possibly some material sources for the formation of the rock bodies which occurred in a syn-collision orogenic environment. |
