项目摘要
It is important to get the knowledge of physical property and strcture of magmatic silicate melts for the better understanding of magmatic process in the Earth. By this reason, we have tried to measure the physical properties such as density, viscosity and the glass-transition temperature of some magmatic silicate melts ; diopside-anorthite and diopside-albite binary joins. The temperature ranged from room temperature to about 1800 0C, and the pressure ranged from 1 b to 20 kb. Based on the experimental results, the relationships between physical properties and physical parameters such as chemical composition and temperature were discussed.The main results are as follows :1. The temperature dependence of viscosity of the present silicate melts can be explained using the configurational entropy theory.2. The configurational entropy of magmatic silicate melts at the glass -transition temperature is the universal constant value, 8.0+1.2 J/K amw, and coincides with the reported value for high-molecular organic substance.3. The WLF(Williams, Landel, Ferry)-equation may be the universal equation which describe the viscosity-temperature relation of magmatic silicate melt independent of chemical composition. And it may be also applicable to the high-pressure condition.4. If we recognize the points 1 and 2, we can predict the viscosity and the glass-transition temperature of mixed melt using the suitable mixing model and the data of physical property of the end member melts.
了解岩浆硅酸盐熔体的物理性质和结构,对于更好地理解地球岩浆作用具有重要意义。为此,我们尝试测量了一些岩浆硅酸盐熔体、透辉石-钙长石和透辉石-钠长石二元熔体的密度、粘度和玻璃化转变温度等物理性质。温度范围为室温至约1800 ℃,压力范围为1 B至20 kb。在此基础上,讨论了化学成分、温度等物理参数与其物理性能的关系,主要结果如下:1。用组态熵理论解释了硅酸盐熔体粘度的温度依赖性.岩浆硅酸盐熔体在玻璃化转变温度下的构型熵为普适常数8.0 ± 1.2J/Kamw,与高分子有机物的文献报道值一致. WLF(威廉姆斯,Landel,Ferry)方程可能是描述岩浆硅酸盐熔体粘温关系的普适方程。它也适用于高压条件。如果我们认识到第1点和第2点,我们就可以利用合适的混合模型和端元熔体的物性数据来预测混合熔体的粘度和玻璃化转变温度。
