英文摘要Pressure and temperature responses of natural phengite [K0.93Na0.03(Al1.46Mg0.45Fe0.09)(Si3.59Al0.39Ti0.02)O-10(OH1.94F0.06)] in ultrahigh-pressure eclogite from the main hole of the China Continental Scientific Drilling Project (CCSD), the DabieSulu orogenic belt have been studied using in-situ high-pressure mid-infrared and high-temperature Raman spectroscopic measurements up to similar to 20 GPa and 800 degrees C, respectively. Linear positive pressure dependences were observed for the infrared absorption bands associated with the aluminosilicate vibrations up to similar to 19 GPa, indicating the steady compression of the structure framework. The frequencies of the 0-H stretching doublet bands, initially at 3601 and 3626 cm(-1), displayed linear downshifts up to 16.6 GPa at - 2.02 and - 2.72 cm(-1)/GPa, respectively, implying high stability of the hydroxyl groups under compression. In the high-temperature Raman spectra, the bands initially centered at 265, 420, 703 cm(-1), and the O-H stretching modes at 3620 cm(-1) exhibited modest linear negative shifts with increasing temperature up to 800 degrees C. Comparisons between experimental results of the present study and those of the previous studies make it plausible that phengite with a higher Si content, i.e., a higher tetrahedral Si/Al ratio, would have higher stabilities under both high pressure and high temperature, and is likely to transport water to greater depths during subduction processes.
