A HRTEM Study of Cronstedtite: Determination of Polytypes and Layer Polarity in Trioctahedral 1:1 Phyllosilicates
Cronstedtite HRTEM Layer Polarity Morphology Polytype Stacking Disorder Trioctahedral 1:1 Phyllosilicates
2011/12/5
Abstract: It is shown that polytypes or stacking sequences of cronstedtite, an Fe-bearing trioctahedral 1:1 phyllosilicate, can be determined using near-atomic high-resolution transmission electron mi...
Perturbative Theory of Mica Polytypism. Role of the M2 Layer in the Formation of Inhomogeneous Polytypes
Crystal Growth Long-Period Polytypes Mica Polytypism
2011/12/2
Abstract: A new model is proposed to explain, within the framework of the theory of spiral growth of Frank, the formation on inhomogeneous mica polytypes. This model relates the interaction and cooper...
Direct identification of the six polytypes of chlorite characterized by semi-random stacking
Direct identification chlorite characterized semi-random stacking
2012/3/31
This paper demonstrates that the six standard polytypes of chlorite, whose definitions are based on the orientation of the interlayer sheet and the position of the interlayer sheet on the 2:1 layer, c...
Formation of regularly interstratified serpentine-chlorite minerals by tetrahedral inversion in long-period serpentine polytypes
Formation of regularly serpentine-chlorite minerals tetrahedral inversion long-period serpentine polytypes
2012/4/5
Serpentinite from Lancaster County, Pennsylvania, consists ofa variety offme-grained serpentine minerals, chlorite, randomly interstratified serpentine-chlorite, and a series of phases based on regula...
Polytype Diversity of the Hydrotalcite-Like Minerals II. Determination of the Polytypes of Experimentally Studied Varieties
Hydrotalcite-like group Polytype X-ray diffraction criteria
2011/12/30
Polytype diversity of hydrotalcite-like minerals is mainly a function of the nature of the interlayer anion. Among the varieties with CO32− anions, only two- and three-layer polylypes having the...
Polytype Diversity of the Hydrotalcite-Like Minerals I. Possible Polytypes and their Diffraction Features
Hydrotalcite-like group Polytype X-ray diffraction criteria
2011/12/30
All possible polytypes of hydrotalcite-like minerals with a periodicity along the c axis of one-, two- and three-layers, as well as the simplest six-layer polytypes, were derived on the basis of the c...
Polytypism of Micas. II. Classification and Abundance of MDO Polytypes
Classification Homomorphy Maximum degree of order Mica Order-disorder Polytype
2012/2/6
The maximum-degree-of-order (MDO) polytypes in all three mica families have been classified into two subfamilies and five homomorphous MDO groups according to their superposition structure and the YZ ...
Polytypism of Micas. I. MDO Polytypes and Their Derivation
Maximum degree of order Mica Order-disorder Polytype
2012/2/6
A procedure leading to the systematic derivation of all maximum-degree-of-order (MDO) polytypes in the three mica families, based on the order-disorder (OD) interpretation of mica structures, has been...
OD-Interpretation of Kaolinite-Type Structures—II: The Regular Polytypes (MDO-Polytypes) and their Derivation
Kaolinite-Type Structures OD-Interpretation MDO-Polytypes
2012/2/14
All MDO-polytypes (i.e. regular polytypes) of trioctahedral, dioctahedral and monoctahedral 1:1 phyllosilicates are derived from their OD-character using the results of our preceding paper. The terms ...
