摘要
磁组构技术作为一种快速、经济和无损性方法测量岩石组构方法，已被广泛用于地质和古今环境研究．随着测试仪器和磁学理论的不断完善，除磁化率各向异性（ＡＭＳ）测量外，近几年非磁滞剩磁各向异性（ＡＡＲ）和等温剩磁的各向异性（ＡＩＲ）的研究较多．同时随着扫描电镜等非磁方法研究和岩石磁性参数测量相结合，人们认识到磁性矿物组成对磁各向异性的重要控制作用．岩石应变磁组构测量在过去几年得到较大发展．岩浆岩的研究主要集中于凝灰岩古代火山口位置推断．沉积岩磁组构研究已显示出其在古今环境研究中的前景．磁组构在石油井下岩芯定向和古水流方向判别等方面的应用亦得到较快发展．
おs a quick,cheap and non-destructive way of measuring rock fabrics,magnetic fabric measurements have become increasingly important means in geoscience and environmental sciences today. With the improvement in laboratory equipment and rock magnetism,besides conventional measurements on anisotropy of magnetic susceptibility (AMS),many investigations emphasize anisotropy of anhysterestic remanence (AAR) and anisotropy of isothermal remanence (AIR). It is proved that magnetic mineral composition has an important control on the magnetic fabric. A big progress of magnetic fabric has been made in studies of rock deformation,location of ancient volcanic sources,and depositional environments. Also the magneitc fabric study shows a great potential application in oil exploration,such as core reorientation and paleocurrent study in ancient sedimentary basins.
