【摘要】 石英双晶的复杂性远远超出了人们的想象。首先介绍了石英的11种双晶律,然后介绍测试鉴定石英双晶律的各种方法及存在的局限性,综述了近年来石英双晶与温压条件关系、晶格结构匹配理论方面的研究成果,最后结合我们近期用EBSD对岩石中石英双晶的观察、测试结果,指出存在的问题及今后的研究方向。更多还原

【Abstract】 The twinning of quartz is too complicate for our imagination.This paper introduces the 11 twin laws of quartz at first.The distinguishing methods of the twin laws and the limitation of each method are also introduced.The research progress in these years about quartz twins related to T-P conditions and the crystal lattice coincidence in the twins is summarized.Based on the EBSD observation about quartz twins in rocks,we point out the problems and the research direction about quartz twinning in the future.更多还原
