Hello? I am eagerly looking for RIR values of some clay minerals. Only several data of non-clay minerals are available here. If possible, let me know the web sites where I can get information. What I want most is RIR values of smectite minerals. Thank in advance. -- Gyoo Ho Lee Dept. of Earth System Sciences, Yonsei University 134 Shinchon-Dong, Seodaemun-Ku, Seoul 120-749, Korea -- TEL : 82-2-361-2665 FAX : 82-2-392-6527 E-mail : [log in to unmask] %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
