摘要

初步研究了百顺地区花岗岩体的地质特征

主要以印支期和燕山期的花岗岩为主。该2期花岗岩体的SiO2和Al2O3质量分数较高

分别为63.60%

5.37%和12.12%

8.78%;SiO2与Al2O3、CaO、MgO、FeO、MnO、K2O、TiO2之间的负相关

以及与Na2O、P2O5之间的正相关都不是很明显。全碱（Na2O+K2O）质量分数均较高

为7.17%

3.77%

为过碱性花岗岩。铝饱和指数（ACNK）在0.92%

.65%之间

碱度指数（A/NK）为1.06%

.80%

为过铝质。

Abstract

The granite geology characteristics of Baishun area are preliminarily discussed

in the main of Indo-Chinese epoch and Yanshan epoch. SiO2and Al2O3contents of these two epochs granites are all relatively high

separately are 63.60%

75.37% and 12.12%

8.78%; the negative correlations of SiO2with Al2O3

CaO

MgO

FeO

MnO

K2O

TiO2are not obvious

the same with positive corrections of SiO2with Na2O、P2O5. The contents of the whole bases（Na2O+K2O） are all high

7.17%

3.77%

so it should be peralkaline granite. The aluminum saturation index（ACNK） are between 0.92%

1.65%

and the alkalinity index（A/NK） are between 1.06% and 1.80%

so it’s peraluminous.
