| 摘 要： | 该区海西期控矿花岗岩分属两大碰撞期的两次侵位,据岩石化学、微量元素及稀土元素所提供的成因信息,每一碰撞期均以同构造碰撞带深熔Ⅰ型斜长花岗岩或花岗闪长岩小侵入体为先导,当碰撞高峰过后在造山晚期,才有S型二长花岗岩和花岗闪长岩岩基就位,无论是Ⅰ型还是S型均为壳源成因。

| Abstract: | Deposit-controlling granites of Northern Boluohuoluo Mountain belong to the products of two periods of intrusion correlated with two period of collision. Petrochemistry, trace elements and rare earth elements indicate that I-type of plagioclase granites or small granitoids were formed at the beginning of every period of collision , S-type of monzogranites and granitoid batholiths were formed after peak period of collision. I-type of porphyritic plagioclase granite bodies and small granitoid body swarm are important for deposit surveying. |
