【摘要】 介绍了岩石磁学研究中常用的能够指示环境变迁和气候变化的几种磁性参数及其组合。研究表明 :磁化率是气候变化的代用指标之一 ,其值的高低反映气候的暖冷和沉积颗粒的细粗 ,用参数 HSIRM,Bcr,HSIRM/k可以识别磁性矿物类型 ,较多磁铁矿的存在指示暖湿的沉积环境 ,反映沉积物颗粒细 ;而较多赤铁矿的存在则指示干冷的沉积环境 ,反映沉积物颗粒粗。 HARM,Bcr,HSIRM/k,S比 ( HSIRM- 1 oom T/HSIRM)在环境监测中有重要的意义更多还原

【Abstract】 several magnetic parameters about rock magnetism may designate environment and climatic changes, susceptibility is one of substitute index when studing climatic change.Its value reflects climatic warm or cold and the grain size of sediments. Parameters H SIRM , B cr , H SIRM / k can distinguish types of the magnetic mineral ,more magnetite designates warm and wet sediment environment, and indicates the grain size of sediments is fine.More hematite designates cold and drought sediment environment, and indicates sediments grain size is coarse . H ARM , B cr , H SIRM / k , H IRM-1oomT / H SIRM (Sratio) are important in environment evaluating.更多还原
