本文讨论了熔体中矿物的热流控制生长。作者按照传导方程的自由边界问题,在地质条件容许的范围内,导出了计算矿物生长速度和生长大小的公式,并以已有实验数据对计算公式进行了验证,还得到了计算透辉石-钙铝辉石固溶体生长速度和生长大小所需的导热系数。讨论认为本文模型适用于自然界在较高温度下从单组份熔体中缓慢结晶的矿物。 This article discusses the heat flow controlled growth of minerals in the melt. According to the free boundary problem of the conduction equation, the formula for calculating the growth rate and growth size of the minerals is derived within the allowable range of the geological conditions. The calculation formula is verified by the existing experimental data, and the formula for calculating the diopside- The thermal conductivity required for the growth rate and growth rate of the Al-Alpnite solid solution. The discussion suggests that this model is applicable to minerals that crystallize slowly from one-component melts at higher temperatures in nature.
