【摘要】A new method is proposed to determine the genetic types of granites.Based on detailed DTA measurements on biotite in granites from south China and the Sanjiang area,characteristic thermal properties are presented for biotites of different origins.Mechanisms are discussed for the differences in thermal behavior of biotite in terms of chemical composition,crystal structure,ordering and polytypism.These characteristic thermal parameters of biotite can be used to shed light on granie genesis with the advantages of rapidness ,simplicity and economy.
