Antigorite, Lizardite and Chrysotile are serpentine minerals which have the same chemical composition but they are formed separately, so what are the conditions that control that?
Have a look at Andreani et al, 2007. This provides links to research on the role of reaction kinetics, P, T and tectonism of formation of the respective minerals species.

Please find attached an excerpt from the book 'Petrogenesis of Metamorphic Rocks of Bucher & Frey (1994). It is the chapter: Metamorphism of Ultramafic Rocks. This chapter is almost everything you need to know about serpentine minerals and serpentinites.
