| 英文摘要 | We have conducted mineral magnetic investigations of polluted topsoil samples, which were collected in the vicinity of a steel plant and a power plant in Sanming City, Fujian Province, southeast China. Our analyses include the temperature-dependence of magnetic susceptibility, hysteresis loops and isothermal remanent magnetization acquisition curves. High-temperature susceptibility measurements suggest that magnetite, hematite and pyrrhotite exist in the polluted topsoil samples All the samples show multidomain or multidomain-like magnetic grain-sizes. For the samples with significantly high susceptibility (chi) and low frequency-dependent susceptibility (chi(fd)), chi and chi(fd) measurements can be used as an effective method for detecting the polluted topsoils. For the samples with relatively low chi and high chi(fd), the presence of ferrimagnetic iron sulphide can serve as a potential pollution indicator in the case that an origin from bedrock weathering has been excluded. We further suggest that mineral magnetic measurements can contribute a,better and more complete understanding of the pollution processes for industrially-polluted topsoils. |
