The layered 1:1 silicate cronstedtite (Fe2+3-xFe3+x)(Si2-xFe3+x)O5(OH)4, (0.5< x< 0.85) belongs to the serpentine-kaoline group. Polytypes are subdivided into four OD subfamilies, or Bailey’s groups A, B, C, D according to different stacking rules. Cronstedtite occurs rarely in low temperature hydrothermal deposits, in certain meteorites (CM chondrites), and presumably on asteroids. Synthetic micrometer-size crystals were prepared by Pignatelli and her co-workers.
