Research Abstract

In the metamorphic rocks, ammonium content of biotites from granulite is low compared with those of biotites from hornblende-biotite gneiss. Systematic decreasing tendency of ammonium content was recognized in biotite from amphibolite facies to granulite facies. Ammonium might be liberated from biotite in the granulite and the ammonium content of the biotites would not record the existence of nitrogen in the original rocks.
Ammonium content of biotites in the granitic rocks studied is closely related to the granite type and the occurrence. In the metamorphic origin granitic rocks, the high ammonium content of their biotites is due to to the metamorphic fluid enriched in ammonium. The ammonium content of biotites is very low low in M-type granite, slightly low in I-type granite, somewhat higher in A-type granite and higher in S-type granite.
