[礦]片鈉鋁石

The dawsonite determined by INCA energy spectrometer is mainly composed of oxygen, sodium, aluminum and carbon. INCA能譜測試表明組成片鈉鋁石的主要元素為氧、鈉、鋁、碳。

More and more evidences suggest that dawsonite is a indicative mineral of CO2-rich fluids and record CO2 and petroleum dual infilling. 越來越多的證據(jù)表明，片鈉鋁石是富CO2流體的指示礦物，記錄了CO2和油氣雙重充注現(xiàn)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氣前形成的自生礦物組合主要為次生加大石英、高嶺石和伊利石，注入CO2氣后形成的自生礦物組合主要為片鈉鋁石和鐵白云石。

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 ： 片鈉鋁石作為膠結(jié)物、自生礦物或脈體，不僅分布在海相白云巖、油頁巖中，而且還廣泛分布在陸源碎屑巖及煤系地層中。
