%X Mineral magnetic parameters were measured on typical soil section derived from quartz in Fengyang County, Anhui Province. Results showed that the contents of magnetic minerals in A layer and B layer were obviously higher than C layer, and the particle sizes of magnetic minerals in A layer and B layer were obviously smaller than C layer. Magnetite dominated magnetic properties of C layer but maghemite dominated A layer and B layer. Maghemite was secondary mineral formed in the process of pedogenesis. The appearance of maghemite in soil and the change of its content can reflect process of pedogenesis. The magnetic enhancement of soil showed that quartzite magnetism had little influences to the magnetism of soil, but pedogenesis and biological action influenced it obviously.
