石榴石是花岗岩类岩石常见的副矿物之一。研究工作表明,石榴石的成分特征反映了花岗岩的成因、演化及其成岩成矿作用的物理一化学条件。因此,在花岗岩及与其有关的各种矿床的研究中,石榴石的成分特征具有重要意义。近年来,国外学者对花岗岩类岩石的石榴石成分特征进行了大量的研究,取得了丰富的资料,提出了有意义的见解。现将他们的研究成果综合、整理如下。
Garnet is one of the common accessory minerals of granitic rocks. Research shows that the compositional characteristics of garnets reflect the genesis and evolution of granites and the physical-chemical conditions of their diagenesis and mineralization. Therefore, the compositional characteristics of garnets are of great importance in the study of granites and various related deposits. In recent years, foreign scholars have done a great deal of research on the garnet composition characteristics of granitic rocks, obtained abundant information and put forward meaningful views. Now their research results integrated, organized as follows.
