| 摘 要： | 通过内蒙古赤峰北部地区花岗岩地球化学数据与国内外各类型花岗岩资料的对比和判别,认为内蒙古赤峰北部地区花岗岩以I型为主,少数具有A型花岗岩的特征.具有高钾和富碱的特点,微量元素表现为富集Ba、Th、K等大离子亲石元素(LILE),而高场强元素(HFSE) Nb、Ti等则相对亏损,其中Sr和P出现强烈亏损.轻重稀土分馏明显...

| Abstract: | Comparison geochemical characteristics of granite from northern Chifeng,Inner Mongolia with various type of granite at home and abroad and the discrimination show that most of the Chifeng granite belongs to I-type granite,and a small number of A-type with.It is with the characteristic of high-K and alkali.The trace elements is rich in Ba,Th,K and other large ion lithophile elements(LILE),while the high field strength elements(HFSE) Nb,Ti,etc.are relatively depleted,which appear strongly depleted in Sr and P... |
