@uhoh "Chrysotile is a layer silicate with the ideal formula Mg3(OH)4Si2O5, composed of one Si-centred tetrahedral (T) sheet joined to one Mg-centred octahedral (O) sheet with a 1:1 (TO) ratio. The TO unit is polar and a misfit exists between the smaller parameters of the T sheet and the larger parameters of the O sheet causing a differential strain between the two sides of the layer. ...

The strain is relieved by rolling the TO layer around the fibril axis to form a cylindrical lattice responsible for the typical fibrous crystal habit of chrysotile (Ballirano et al., 2017 ▸)."

The original ref is Ballirano, P., Bloise, A., Gualtieri, A. F., Lezzerini, M., Pacella, A., Perchiazzi, N., Dogan, M. & Dogan, A. U. (2017).

London: European Mineralogical Union and the Mineralogical Society.
That only begins to scratch at the surface of your questions.
This is also a nice ref: southalabama.edu/geology/haywick/GY302/302write-1.pdf but is still not addressing your questions.

@BuckThorn Oh fascinating stuff! I will get those tomorrow and start reading, thank you!
