摘要
石英在爆裂法测试中常出现α－β峰，此峰是由爆裂温度大于５７３℃的高温流体包裹体，在α石英相变成β石英时，包裹体发生泄漏（非爆裂）形成的．在金矿地质找矿中，用α－β峰可判断矿脉的剥蚀程度。
In decrepitation test for quartz,α β peaks frequently appear when the samples are heated to the temperature of 573℃.Study shows that the α β peak is produced by the leaking(without decrepitating) of high temperature inclusions whose decrepitating temperature is higher than 573℃,the critical point when α quartz converts into β quartz This form of peak may be used to infer the denuded degree of lodes and decide the origin of deposits in gold ore exploring
