摘要：

The effects of loess thinning and natural soil drainage on profile distribution of clay and free oxides of Fe, Al, Mn, and Si were determined using 14 soils. The most significant result was an increase in free SiO//2 in fragipans. It is proposed that free silica precipitates in this horizon and binds soil particles together to form fragipans. The silica may interact with aluminum hydrous oxides on clays.
