| 摘 要： | 本文对采自华南两个成岩成矿系列花岗岩中的黑云母进行了DTA特征和其他热性质的比较。发现可根据黑云母的OH脱失峰温度、熔化吸热峰的形状、熔化热及熔化后产物的形态来区分不同成因的花岗岩。文中还探讨了造成黑云母热性质差异的原因。

| Abstract: | A comparison has been made of DTA data and other thermal properties ofbiotite samples from the two petrogeno-mineralized series of granites in southChina. It is found that different genetic types of granites can be effectivelydistinguished in the light of significant differences in OH-releasing temperature,melting endothermic peak shape, heat of fusion and cooled melt shape for bio-tites from the two petrogeno-mineralized series of granites in southChina. A new rapid approach based on DTA has been established with whichdifferent genetic types of granites can be distinguished. Also discussed in thepresent paper are the reasons responsible for the differences in thermal proper-ties of the biotites from these two granite series. |
