WebNote, however, that the here-studied convection driven by thermal gradients will be superimposed by solutal convection in an actual growth experiment. Due to the presumably faster dissolution in the upper zone, the density of the solute-containing fluid there will likely increase faster compared to the density of the fluid in the growth zone. WebDissoluble minerals are often shaped by chemical erosion. In the case of fast kinetics of dissolution, local erosion rate is set by the advection of the solute. Even in absence of an …
