摘要
中生代是华熊地块最重要的岩浆作用时期。通过对其中主要地体中燕山期改造型花岗岩和同熔型花岗岩的同位素研究,结合其形成物质背景和地质特征,认为它们的物质特征主要取决于它们继承各自不同的地体物质(特别是基底物质)和同一地体物质的多少程度。地体及其中生代岩浆作用的构造环境是解释这一继承机理的主要因素。
The Mesozoic is the most important period of magmatism in the Huaxiong Block. According to studies on the isotope of Yanshanian transformation granites and syntexis granits in combination of their matter settings and geological charaterteristics, the paper holds that their matter characteristics mainly depend on the amount of the matter inherited from various terrances especially the basements and inherited from the same terrance. Terrances and their mesozoic tectonic environments of magmatism are the main factor that explains the inheritance mechanism.
