摘要

摘要: 为了探讨接触变质带内变碳酸盐岩变质过程CO₂释放的数量和排放CO₂的物理、化学及地质条件,根据递进变质反应和时间积分流体通量模型,定量分析和定量计算了双山地区变碳酸盐岩在接触变质作用中释放CO₂的通量。计算结果得到CO₂的通量值为0.729×10⁴~2.446×10⁴ mol/cm²,CO₂的来源以接触变质反应释放为主;CO₂的生成释放与变质程度呈正相关关系。自白云石带至方解石带变质流体中X_CO₂不断升高,但钙铝榴石带由于岩浆水影响,流体通量最高而X_CO₂急剧下降。

Abstract: To discuss that metamorphic carbonate rocks release the amount and ability of CO₂ and CO₂ releasing conditions,CO₂ flux, which metamorphic carbonate rocks release in contact metamorphism, is analyzed and calculated quantitatively on the basis of metamorphic reaction and time integrated fluid flux. The results suggest that the value of CO₂ flux is 0.729×10⁴~2.446×10⁴ mol/cm²,CO₂ is provided mainly by contact metamorphic reations. The generation and release of CO₂ are positive correlation with the degree of metamorphism, and X_CO₂ in fluids continuously increases form the zone of dolomite to the zone of calcite, but in the zone of essonite, fluid flux is the largest and X_CO₂ sharply decreases for the influence of magmatic water.
