The Clay mineralogy and pedogenic processes in soil of two inland va/Jey swamps were investigated. Both field morphologic observations and particle size distribution indicate /ithologic discontinues in only two (pedons AB-2 and AB-5) of the nine pedons studied. Clay minera/Ogy was predominantly kaolinitic except in pedons BD-1 and BD-2 which contained some degraded mica minerals. Ferro/ysis was well demonstrated in pedons BD-1 and BD-2. Decomposition processes of minerals Jed to the fonnation of some degraded mica.

Keywords: clay, ferrolysis, kaolinite
