Gibbsite clay
WebThe mobility of major, trace and REE's during the progressive kaolinization of andesitic materials by fresh water with gibbsite, feldspar, quartz, illite, smectite but without zeolite, has been investigated to reveal petrogenesis of Upper Cretaceous volcanism as a parent rock and to explain mineralogical processes of kaolin deposit as a ... WebIn contrast, aging in the presence of various clay minerals and gibbsite retarded (kaolinite, illite, smectite, gibbsite) or even blocked (soil smectite, allophane) transformation. The conversion rate was inversely related to the final Si concentration in solution. In addition, the presence of clay minerals resulted in higher hematite to ...
