Structure of the 30-sectored polygonal serpentine; a model based on TEM and SAED studies






Physics and Chemistry of Minerals 24(1): 39-49

Structure of the 30-sectored polygonal serpentine; a model based on TEM and SAED studies

Polygonal serpentine (PS) from selected serpentinite were studied using transmission electron microscopy. Fiber axis selected-area electron diffraction (SAED) patterns and electron micrographs reveal orthogonal and monoclinic lizardite polytypes. The PS models by Chisholm (1992) and Baronnet etal. (1994) do not fit SAED measurements. Experimental results are matched with calculated diffraction geometry and intensities, as well as with simulated images, indicating inversion of the tetrahedral layer at sector boundaries. The structural relationships between chrysotile and PS are discussed.
