磁化率是表征岩石受磁化难易程度的物理量,其相关研究在20世纪上半叶就已开始(张世红等,2005),最初主要用于研究沉积岩与沉积物。一般认为岩石磁化率大小与矿物的类型、含量、颗粒大小与结构,以及温度压力有关。其中矿物磁性大小对岩石磁化率影响很大(郎元强等,2011;刘天佑,2007)。藏东地区在区域构造上处于特提斯一喜马拉雅构造域的东南部,属南
Magnetic susceptibility is a physical quantity that characterizes the degree of susceptibility to rock magnetization. Related studies began in the first half of the 20th century (Zhang et al., 2005) and were primarily used to study sedimentary rocks and sediments. Rock magnetic susceptibility is generally believed to be related to the type, content, particle size and structure, and temperature and pressure of the mineral. Among them, the magnetic magnitude of minerals has a great influence on the rock susceptibility (Lang et al., 2011; Liu Tianyou, 2007). The eastern Tibet is structurally located in the southeast of the Tethys-Himalayan tectonic domain,
