摘要
对登龙、热加地区晚三叠世三个不同火山旋回玄武岩的地球化学特征与板块构造环境进行了分析,指出了义敦岛弧的张性特征及其与成矿作用的关系.
The geochemical characteristics and platetectonic environments of Late Trissic basalts from three volcanic cycles of DenglongRejia area are discussed in this paper.It indicates that Yidun volcanic arc was an extensional arc,the extension of the volcanic arc was an important metallogenetic factor.
