Kaolin and Zeolite Research

Below is a list of publications related to the origin and genesis of kaolin and/or zeolites. Most of the research has been conducted in association with kaolin deposits in central Georgia, USA and in western Turkey. The zeolite work is in association with Turkey and the Georgia Coastal Plain Floridan aquifer.
