其中不对称Ca Mg混合模型得到W =36.32±0.34（单位kJ），W =32.72± 0.32，而对称Ca Mg混合模型的结果为W =34.05± 0.22.非对称Ca Mg混合模型与镁橄榄石固溶线数据拟合较好.结果表明，随着压力的增加，固溶线变窄，这是由于Ca Mg橄榄石固溶体的负过剩体积引起的，而压力对固溶线的影响不大。
where the asymmetric Ca Mg mixing model yielded as W =36.32±0.34(unit in kJ),W =32.72± 0.32,whereas the symmetric Ca Mg mixing model resulted as W =W =34.05±0.22.The asymmetric Ca Mg mixing model fits wel with the data of the forsterite monticelite solvus.The present results are consistent with the previous analyses of miscibility gaps in Ca Mg olivines,and the deviation from the ideality of Ca Mg mixing is slightly smaler than the previous estimates.Compared with the previous data, the solvus becomes narrow with the increase of pressure.The negative excess volume of Ca Mg olivine solid solution causes this character,but the pressure efect on the solvus is smal.
