Abstract

With increasing iv Al substitution and increasing total layer charge, the 29 Si NMR chemical shifts for specific types of Q 3 (nAl) sites in 2:1 layer silicates become progressively deshielded (less negative). This deshielding is related to both structural distortions caused by mismatch of the tetrahedral and octahedral sheets and compositional variations in the octahedral sheet.-J.A.Z.
