碳酸镁钙（CaMg (CO3)2），主要是由碳酸钙与碳酸镁所组成的矿物（CaCO3与MgCO3的比例大致为1：1）。 属于不溶物，是一种弱电解质，晶体属三方晶系的碳酸盐矿物，是白云石的主 …

2008年8月30日 · We show that through most of the P–T conditions of the mantle, MgCO 3 is the major host of oxidized carbon in the Earth. We discuss the possibility of CO 2 release at the …

Starting from 1425 °C at ≤ 30 mol% CaCO 3 in the system, the liquid quenches to dendritic carbonate and periclase and contains rounded voids, indicating an incongruent melting …

The solid solubility, disorder, and decomposition relationships in the system CaCO 3 -MgCO 3 were investigated in the pressure range of from 10 to 10,000 bars and at temperatures of from …

摘要 本文详细报道了两种晶体——菱镁矿 (MgCO3) 和方解石 (CaCO3) 的结构、电子、光学和弹性特性的从头算计算。 这两种化合物都是重要的天然矿物质，在二氧化碳循环中发挥着重要 …

2019年6月5日 · Atomistic simulations provide a meaningful way to determine the physicochemical properties of liquids in a consistent theoretical framework.

Among the constituents of ancient carbonate rocks, dolomite, CaMg (CO 3) 2 is second in importance after calcite. Although both minerals may be found associated in dolomitic …

2011年2月15日 · Detailed ab initio calculations of the structural, electronic, optical and elastic properties of two crystals – magnesite (MgCO 3) and calcite (CaCO 3) – are reported in the …

Starting from 1425 °C at ≤30 mol% CaCO 3 in the system, the liquid quenches to dendritic carbonate and periclase and contains rounded voids, indicating an incongruent melting …

摘要 在 CaCO3-MgCO3 系统中进行了多砧实验，压力为 5.0-7.0 GPa，温度为 800-1600 °C。 反应白云石 = 文石 + 菱镁矿已被逆转，在 5.0 GPa 时位于 750 °C、6.0 GPa 时位于 900 °C 和 …
