岩浆演化过程中,微量元素的行为各不相同。研究这些元素在岩浆作用中的迁移规律、存在形式和相互关系,对于解决许多成岩、成矿理论问题,探讨矿床成因以及揭示岩浆岩含矿性的地化标志等方面具有重要意义。日本熊本大学津末昭生教授根据日本西南部花岗岩带中磷灰石、黑云母、角闪石等的氟、氯测定结果,分析研究了氟、氯两种元素在花岗岩浆中的地化行为,得出以下几点认识。
During magmatic evolution, the trace elements behave differently. Studying the migration rules, existing forms and interrelations of these elements in magmatism plays an important role in solving many diagenesis and metallogenic problems, exploring the genesis of the orebodies, and revealing the geochemical sign of magmatic rocks. Based on the results of determination of fluorine and chlorine in apatite, biotite and amphibole from the granite belt in the southwestern part of Japan, Prof. Tsujin Akira of Kumamoto University in Japan analyzed the geochemical behavior of both fluorine and chlorine in granite magma. Out of the following understanding.
