| 摘 要： | 为了建立江汉平原沉积物示踪的磁学模型,对汇入江汉平原的主要河流现代沉积物磁学特征进行了研究,结果表明:(1)在江汉平原范围内,无论长江、汉江,还是周边的漳河、沮水、玛瑙河和清江,它们的现代沉积物的磁学参数特征均显示出明显的差异,而且和源区表壳岩性也显示出极好的相关性；(2)长江和汉江现代沉积物中铁磁性矿物均以亚铁磁性矿...

| Abstract: | In this paper we report the magnetic characteristics of the confluent river sediments into the Jianghan Plain.Magnetic characteristics are obviously different between different rivers,such as the Yangtze River,Hanjiang River,Zhanghe River,Juhe River,Manaohe River and Qingjiang River,and are well correlated with rock types of the provenance.Magnetic minerals from the Yangtze River and the Hanjiang River are almost ferrimagnetic,which dominate the magnetic characteristics of the samples.Content of ferrimagnet... |
