| 摘 要： | 喜山期富碱岩体广布于滇西北地区 ,通过对其地质学和岩石化学特征的研究 ,认为富碱岩体 (脉 )由正长 (斑 )岩、二长斑岩、花岗斑岩及相关的火山岩组成 ,具有多次活动的特征 ,并形成区内富有特色的岩浆岩系列 ;该系列岩浆岩以富碱高钾为突出特点 ,具有正常的岩浆演化趋势 ,不同岩带岩石地质学和岩石化学方面有区域性变化规律。

| Abstract: | Alkali rich intrusive bodies are widely distributed in Northwestern Yunnan province. It is believed through the study of its geological and rock chemical characteristics that alkali rich intrusive body is composed of syenite (porphyry), monzonite porphyry, granite porphyry and related volcanic rocks characterized by several times of activities and foming an unique magmatite rock series in the region. Magmatites of the series show obvious characteristics of alkali rich and Potassium rich with a normal magma evolution trend. Rock geology and rock chemistry in various rock zones have regional changing rules. |
