  abstract = {{I}nterest is growing in nanoparticles made of earth abundant materials, like alumino(silicate) minerals. {T}heir applications are expanding to include catalysis, carbon sequestration reactions, and medical applications. {I}t remains unclear, however, what factors control their formation and abundance during laboratory synthesis or on a larger industrial scale. {T}his work investigates the complex system of physicochemical conditions that influence the formation of nanosized alumino(silicate) minerals. {S}amples were synthesized and analyzed by powder {X}-ray diffraction, in situ and ex situ small angle {X}-ray scattering, and transmission electron microscopy. {R}egression analyses combined with linear combination fitting of powder diffraction patterns was used to model the influence of different synthesis conditions including concentration, hydrolysis ratio and rate, and {A}l?:?{S}i elemental ratio on the particle size of the initial precipitate and on the phase abundances of the final products. {T}hese models show that hydrolysis ratio has the strongest control on the overall phase composition, while the starting reagent concentration also plays a vital role. {F}or imogolite nanotubes, we determine that increasing concentration, and relatively high or low hydrolysis limit nanotube production. {A} strong relationship is also observed between the distribution of nanostructured phases and the size of precursor particles. {T}he confidences were >99% for all linear regression models and explained up to 85% of the data variance in the case of imogolite. {A}dditionally, the models consistently predict resulting data from other experimental studies. {T}hese results demonstrate the use of an approach to understand complex chemical systems with competing influences and provide insight into the formation of several nanosized alumino(silicate) phases.},
