来自不同地质背景的八个方柱石样品;马里阿利特-梅奥尼特系列。TG和DTA用于定义在加热过程中挥发性组分的释放。在800 ℃以下的温度范围内，观察到H2O、SO2、CO2、NaCl和KCl的排放连续发生，但有五个明显的阶段。在气相中存在的SO2可能是由于分解反应。X射线粉末衍射图表明a和V的增加，其趋势与每个样品中存在的钙镁石的百分比成反比。晶格常数随温度的升高而增大，镁铝榴石含量随温度的升高而增大，其关系式为：da/dT = -1.59 × 10（sub-6）ME% + 1.85 × 10（sub-4）（r2 = 0.996），dV/dT = -0.3 × 10（sub-3）Me% + 0.034（r2 = 0.998）。修改期刊摘要。
Eight scapolite samples from different geologic settings; marialite-meionite series. TG and DTA were used to define the release of the volatile components during heating. In the temperature range up to 800 degrees C, the emission of H 2 O, SO 2 , CO 2 , NaCl, and KCl was observed to occur continuously, but with five evident steps. The presence of SO 2 in the gaseous phase may be due to decomposition reactions. X-ray powder diffractograms indicated an increase in a and V, with a trend inversely proportional to the percentage of meionite present in each sample. Increases in lattice parameters, with rising temperature, and percentage of meionite may be expressed by the equations: da/dT = -1.59 X 10 (sub -6) ME% + 1.85 X 10 (sub -4) (r 2 = 0.996);dV/dT = -0.3 X 10 (sub -3) Me% + 0.034 (r 2 = 0.998).--Modified journal abstract.
