| 摘 要： | 高温高压岩石流变仪围压标定的主要方法为氯化盐类的部分熔融法和矿物相变法。利用氯化盐类进行压力标定时,不仅可以利用单一盐类,也可以使用多种盐类的混合物;常用的压力标定矿物相变及其适用温压范围如下:石英-柯石英,500~1200℃、2.5~3.2GPa;钠长石-硬玉+石英,600~1200℃、1.6~3.2GPa;铁橄榄石+石英-铁辉石,600~1200℃、1~1.7GPa;磷镁石-Mg3(PO4)2-Ⅱ,565~825℃、0.6~0.9GPa;方解石-文石,600~1200℃、0.5~2.5GPa。不同的标定方法具有不同的特征,文中将进行详细介绍。

| Abstract: | The best methods of calibrating confined pressure for rock rheometer under high temperature and high pressure are the method of partial melting of salt and the method of mineral phase transition. Not only the single chloride salt but also the mixture of different salts can be used to calibrate the confined pressure. The mineral phase transitions commonly used are the following: quartz-coesite, 500-1200 ℃, 2.5-3.2 GPa; albite-jadeite+quartz, 600-1200 ℃, 1.6-3.2 GPa; fayalite+quartz-ferrosilite, 600-1200 ℃, 1-1.7 GPa; farringtonite-Mg3(PO4)2-II, 565-825 ℃, 0.6-0.9 GPa; calcite-aragonite, 600-1200 ℃, 0.5-2.5 GPa. The characteristics of these methods are different, which are introduced in this paper. |
