GEOLOGICAL FEATURES OF THE ZHUYANGOU SUPER-UNIT,INNER MONGOLIA
-
摘要: 朱沿沟岩体是中酸性复式岩体，共圈定出２６个侵入体，建立５个单元。该岩体是在燕山早期同一大地构造环境下，上地慢基性岩浆在一次热事件中，经多次脉动所形成的超单元。Abstract: The Zhuyangu rock body is an intermediate-acid multiple intrusion. Twenty-six intrusivebodies have been delineated and five units established. It is considered that this multiple intru-sion is a super-unit resulting from multiple pulsations of basic magma from the upper mantle ina thermal event in the same early Yanshanian tectonic environment.
