At the polar angle 66.9° the crust growth period was influenced by the melt temperature evo- , lution. As shown in Figure 14, in contrast with the melt temperatures in the middle and lower parts of the vessel, the melt temperature in the upper part of the pool increased slightly at the beginning and then decreased to a constant value. It took about 2000 s for the melt to reach the steady-state temperature. This time period represents also the crust growth period at the polar angle 66.9° The crust growth rates R calculated in Table 13 are shown in
