【摘要】 |
|
In this study, a set of environmentalmagnetic parameters (χlf, χfd%,χARM, SIRM, HIRM, SOFT and SIRM/χlf, χARM/SIRM and χARM/χlf) of 331 top-soil samples from Xinjiang Uygur Autonomous Region of China were systematicallymeasured and themagnetic characteristics and its environmental significance were discussed. Our results indicate that themainmagneticminerals of these top-soils are single-domainmagnetite. The content ofmagneticminerals in top-soils from north Xinjiang is higher than that from south Xinjiang; however, the content of hardmagneticminerals is higher in the top-soils from south Xinjiang. The top-soils from Yili region contain similarmagneticminerals as that from south Xinjiang, but withmuch strongermagnetic SP content due to higher pedogenic processes. The differences inmagnetic characteristics among top-soils from different regions of Xinjiangmight reflect the differences of regional climatic factors, especially the precipitation. |
