中文摘要：

为了对比研究不同矿物压力计的可靠性和准确性,选择姑婆山-花山花岗岩体中5个不同的单元作为研究对象,对其进行角闪石和黑云母全铝压力计的计算,其中杨梅山独立侵入体以角闪石和黑云母计算的成岩压力分别为3.23×108和0.90×108Pa,对应的形成深度分别为12.8和3.58 km;里松单元以角闪石和黑云母计算的成岩压力分别为3.47×108和1.00×108Pa,对应的形成深度分别为14.29和4.08 km;望高单元、新路单元与华美单元以黑云母计算的成岩压力分别为1.24×108、3.49×108和2.20×108Pa,对应的形成深度分别为5.13、14.48和8.3 km。通过综合对比前人的研究成果,发现角闪石比黑云母更加适合作为全铝压力计目标矿物。

英文摘要：

For studying the reliability and accuracy of different minerals barometer,data of Al-in-hornblende and biotite barometer from five units of Guposhan-Huashan granite in north Guangxi is reported.Calculated formation pressures of Yangmeishan intrusion based on hornblende and biotite are 3.23×108 and 0.90×108 Pa,the corresponding formation depths are 12.8 and 3.58 km.Lisong unit calculated formation pressures based on hornblende and biotite are 3.47×108 and 1.00×108 Pa,the corresponding formation depths are 14.29 and 4.08 km.The calculated formation pressures of Wanggao unit,Xinlu unit and Huamei unit based on biotite are 1.24×108,3.49×108 and 2.20×108 Pa,the corresponding formation depths are 5.13,14.48 and 8.3 km.In the contrast with previous results it is suggested that the hornblende is more suitable for target mineral of Al-barometer than biotite in general.
