[矿]片钠铝石
The dawsonite determined by INCA energy spectrometer is mainly composed of oxygen, sodium, aluminum and carbon. INCA能谱测试表明组成片钠铝石的主要元素为氧、钠、铝、碳。
More and more evidences suggest that dawsonite is a indicative mineral of CO2-rich fluids and record CO2 and petroleum dual infilling. 越来越多的证据表明，片钠铝石是富CO2流体的指示矿物，记录了CO2和油气双重充注现象。
The authigenic minerals include secondary overgrowth quartz, kaolinite and illite before CO2 influx.After CO2 influx, the main cements include dawsonite and ankerite. 注入CO2气前形成的自生矿物组合主要为次生加大石英、高岭石和伊利石，注入CO2气后形成的自生矿物组合主要为片钠铝石和铁白云石。
Abstract : As cement, authigenic mineral or vein, dawsonite is found not only in marine dolomite and oil shale, but also in terrigenous fragmentary rock and coal measures. 摘要 ： 片钠铝石作为胶结物、自生矿物或脉体，不仅分布在海相白云岩、油页岩中，而且还广泛分布在陆源碎屑岩及煤系地层中。
