片钠铝石

According to the fact that dawsonite and ankerite are the authigenic minerals forming at latest in sandstone, CO2 infilling was relatively late, possibly 46.2±2.1 Ma or later.

结合片钠铝石和铁白云石是砂岩中最晚形成的自生矿物，认为CO2注入时间相对较晚，可能为46.2±2.1Ma或者更晚。

The paragenetic sequence are in the order of calcite-kaolinite, secondary quartz overgrowths-illite-dawsonite and ankerite.

成岩共生序列依次为方解石-自生高岭石、次生加大石英-伊利石-片钠铝石、铁白云石。

The dominant cements and authigenic minerals include dawsonite, ankerite, calcite, secondary quartz oergrowths and authigenic clay mineral.

胶结物与自生矿物主要为片钠铝石、铁白云石、方解石、次生加大石英、自生粘土矿物。

In Surennuoer faulted zone, the authigenic mineral assemblage of dawsonite and ankerite are formed during the mutual action between CO2 fluids and sandstone, and then the reservoir properties of dawsonite-bearing sandstone becomes poorer.

苏仁诺尔断裂带CO2流体在与砂岩相互作用过程中，形成了片钠铝石和铁白石的自生矿物组合，导致研究区含片钠铭石砂岩储层物性变差。

The authigenic minerals formed before CO2 charging include multi-stages of calcite assemblages, kaolinite and secondary quartz overgrowths assemblages. While the main cements formed after CO2 charging are dawsonite and ankerite.

CO2注入前形成的自生矿物组合主要为多期方解石组合，高岭石、次生加大石英组合；CO2注入之后形成了片钠铝石和铁白云石组合。

Part of dawsonite occurs as radial, bundle and plate, and some are very special as large massive condensates.

片钠铝石一部分以放射状、束状和板状等产出，另一部分呈凝块状大面积地连片出现，尤为特殊。

Two genetic types of dawsonite, namely inorganic and organic are divided in response to origin of carbon dioxide. Inorganic genesis includes magmatic origin and carbonate decomposition origin.

CO2气的来源决定了片钠铝石具有无机和有机两大成因类型，其中，无机成因包括岩浆成因和碳酸盐热解成因。

High CO2 pressure, temperature range between 25-100℃ and alkaline-weak acidic fluid is necessary for generating dawsonite.

片钠铝石是在高CO2分压，温度在25℃-100℃，碱性-弱酸性流体条件下形成的。

The calculated δ13C values of CO2 gas being in equilibrium with dawsonite ranged from -8.7‰ to-6.9‰ and was in coincidence with the δ13C values ranging from -9.76‰to -5.74‰ of CO2 gas in Gudian carbonate dioxide gas field.

由于含片钠铝石砂岩与CO2气的分布都受控于深大断裂和玄武岩，CO2气和形成片钠铝石的CO2绝大部分属于幔源岩浆型。
