英文摘要	在金刚石压腔中,运用激光拉曼光谱技术对高压下蛇纹石矿物结构及其稳定性进行了原位观测与研究。实验获得蛇纹石在常温下从0.1～5 140MPa的拉曼光谱数据。研究发现,蛇纹石低频拉曼谱峰388,471,692和705cm-1随压力增加有规律地向高频偏移;层内羟基3 664cm-1峰和层间羟基3 696cm-1峰与压力呈明显的正相关性。层内羟基3 664cm-1峰随压力变化的斜率为3.3cm-1.GPa-1,层间羟基3 696cm-1峰在2.0GPa时斜率由8.3cm-1.GPa-1变为1.1cm-1.GPa cm-1。在实验温压条件下,蛇纹石未发生脱水作用。; Within the diamond anvil cell, the Raman spectroscopic study of serpentine was operated at room temperature and under pressures from 1 atm to 5 140 MPa. This study analyzed the pressure dependence of the low-frequency Raman vibrational modes of serpentine at 388, 471, 692 and 705 cm(-1) respectively. The vibrational modes of inner OH groups at 3 664 cm(-1) and inter-layer OH groups at 3 696 cm(-1) shifted linearly with the increasing pressures. The pressure-related slope of 3 664 cm(-1) was 3.3 cm(-1) x GPa(-1). The vibrational mode at 3 696 cm(-1) of the inter-layer hydroxyl shifted upwards with the pressure-related slope 8. 3 cm(-1) x GPa(-1) up to 2.0 GPa, and then with 1.1 cm(-1) GPa(-1) from 2.0 GPa to ca. 5.0 GPa. It could be interpreted that the hydrogen bond of the inter-layer hydroxyl made dominant contribution to such experimental phenomena. In addition, the dehydration of serpentine did not occur under such conditions.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000287263400025&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); EI; PubMed; 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 1; 02; 398-401; 31
