在30kbar压力下进行了肇东陨石的加热-熔融实验。实验结果表明。从840℃至2050℃,陨石中的金属-硫化物相经历了熔融—两相混溶的过程,最终形成一种Fe、Ni、Co、S之比不相等的多相混合物。而陨石中的硅酸盐相经历了热变质—熔融—熔融分异的过程。初熔温度为1610℃,2050℃时熔体发生分异,有富Si、Al的硅酸盐新相分离出来。以上述结果为依据,本文对类地行星早期层圈构造的形成机制进行了探讨和推论。 Under the pressure of 30kbar, the heating-melting experiment of Zhaodong meteorite was carried out. Experimental results show. From 840 ° C to 2050 ° C, the metal-sulphide phase in meteorites undergoes a melt-two phase miscibility process, eventually forming a heterogeneous mixture of unequal ratios of Fe, Ni, Co and S. The silicate phase in meteorites has undergone thermal metamorphism-melt-melt differentiation process. Melting temperature of 1610 ℃, 2050 ℃ when the melt differentiation, there Si, Al-rich silicate new phase separation. Based on the above results, this paper explores and deduces the formation mechanism of the early earth-ring structure of the geosynchronous Earth.
