脆韧性剪切带变碳酸盐岩CO_2的释放能力——以郯庐断裂系南段双山断裂为例

CO_2-RELEASING ABILITY OF METAMORPHIC CARBONATE ROCKS IN CRISP-TENABLE CUT STRIP──TAKING SHUANGSHAN FAULT IN SOUTHERN TANLU FAULT FOR EXAMPLE

为求算经受动力变质作用岩石释放CO2 的能力 ,特选择变碳酸盐岩区的一条脆韧性断层岩 ,对其进行构造蚀变岩石矿物学和地球化学分析 ,求得每 1 0 0克碳酸质母岩在蚀变反应过程中可释放 3 3 .90克CO2气体分子 ,其质量占母岩质量的 1 / 3 ;

Mass change of metamorphic carbonate rocks, which is affected by the Shuangshan fault, is calculated in the crisp-tenable cut conditions, and the CO\-2-releasing amount is analyzed in dynamical metamorphism. The result is that 100g carbonate can release \{33.90\}g CO\-2, accounting for one-third of the resource rocks. Liquids played an important role in carbonatite dynamical alternation.
