Short summary
We performed experiments to investigate the effect of water and chlorine on the growth of minerals called plagioclase, motivated by the evidence for the presence of water and chlorine with the formation of rocks with large plagioclase minerals. Our study shows that indeed water has an effect on the size and abundance of that mineral. The effect of chlorine on the growth characteristic is negligible. Our results have implications for the understanding of the formation of different rock textures.
