试论花岗岩类的地质环境分类

对以往花岗岩类的地质环境分类分析，可以归纳出分别强调时间和空间作为分类原则的二大类，花岗岩类的岩石学特征及成因随时空环境而有规律演变，其地质环境分类的原则应同时包括时间和空间二大因素。在此基础上，提出了花岗岩类的时空分类。

ON GEOLOGIC ENVIRONMENTAL CLASSIFICATION OF GRANITOID

An analysis on the existing geologic environmental classifications of granitoid shows that they can be grouped into two broad classes: those laying emphasis on time and those laying emphasis on space. However, as the petrological features and origins of the granitoid evolve regularly with spatial and temporary environments, the author holds that geologic environmental classification of granitoid should be based on both the spatial and the temporary factors. Hence, a new space _time classification scheme is put forward for granitoid in this paper.
