11 p, 1.0 MB Bromide-ion distribution in the interlayer of the layered double hydroxides of Zn and Al : Observation of positional disorder / Prasanna, S.V. (Bangalore University. Department of Chemistry) ; Radha, A.V. (Bangalore University. Department of Chemistry) ; Kamath, P.V. (Bangalore University. Department of Chemistry) ; Kannan, S. (Council of Scientific and Industrial Research. Discipline of Inorganic Materials and Catalysis)
Because of the anisotropy in bonding, layered hydroxides crystallize with extensive structural disorder due to the incorporation of stacking faults. In contrast, the loss of crystallinity in Br -ion intercalated layered double hydroxides (LDHs) arises due to the positional disorder of Br in the interlayer. [...]

Illite age analysis (IAA) is a classical method for extracting diagenetic and detrital ages from mixed ages measured by K-Ar. This approach is based on measuring the masses of diagenetic and detrital illitic components in a few different grain-size fractions of one rock sample and measuring the mixed ages of these fractions.
