1) Recently I completed to collect X-ray diffraction patterns for simple carbonate systems Na2CO3, K2CO3, CaCO3, and FeCO3 in the range 1-30 GPa and 27-1400℃ to constrain phase relations and EOS. 2) I supposed mechanism and estimated possible rates of carbonatite±H_2O and hydrous melt ascent from the transition zone and might be lower mantle. This mechanism so called"dissolution-precipitation" controlled by diffusion transport of silicate components via hydrous or carbonatite melt. 3) I collected experimental data point to constrain phase diagrams and melting phase relations in simple carbonate systems (K-Mg, K-Ca, Na-Mg, Na-Ca, K-Ca-Mg, Na-Ca-Mg, K-Na-Ca-Mg)at the conditions corresponding to the basement of lithospheric mantle.

1)最近，我完成了在1-30 GPa和27-1400℃范围内收集简单碳酸盐体系Na_2CO_3、K_2CO_3、CaCO_3和FeCO_3的X射线衍射图，以约束相关系和状态方程。2)推测了碳酸盐岩和含水熔体从过渡带上升到下地幔的可能机制和速率。这种机制被称为“溶解-沉淀”，它受硅酸盐组分通过含水或碳酸盐熔体的扩散输运控制。3)本文收集了实验数据点，以约束岩石圈地幔基底条件下简单碳酸盐体系（K-Mg，K-Ca，Na-Mg，Na-Ca，K-Ca-Mg，Na-Ca-Mg，K-Na-Ca-Mg）的相图和熔融相关系。
