白云石

The paragenetic sequence of outcrop sandstones may induce to ealy compaction diagenetic facies、carbonate cementation diagenetic facies and feldspar dissolving diagenetic facies, the diagenetic facies of core sandstones are ealy compaction diagenetic facies、ankerite diagenetic facies、authigenetic quarze and kaolinite filling diagenetic facies.

露头砂岩的成岩组合可归纳为早期压实成岩相、碳酸盐胶结成岩相和长石溶解成岩相，岩芯砂岩成岩相为早期压实成岩相、铁白云石胶结成岩相、自生石英与高岭石充填成岩相。

Theresults indicated that the aggregates in this experiment are all argillaceous carbonate rockscontained alkali reactive minerals such as chalcedony and dolomite.

结果表明，三种骨料样品均为粘土质碳酸盐，含有玉髓和白云石等碱活性矿物，具备AAR 发生的岩相特征。

Dolomite also occurs in this mode as replacement of limestone along major fractures and betts of enclosed breccia.

沿包围角砾岩的主要裂隙带，以交代石灰岩的方式，也能形成白云石。

Most dolomite is obviously the result of replacement of precursor calcite but certainly not all.

多数白云石显然是原来方解石交代的结果，但肯定不是全部。

The most important include calcium oxide, calcium hydroxide, calcite and dolomite.

其中最重要的有氧化钙、氢氧化钙、方解石和白云石。

The reaction mechanism of carbonation for the production of light magnesium carbonate from dolomite is discussed.

探讨了白云石碳酸化法生产轻质碳酸镁过程中碳酸化反应机理。

Dolomites that generated abundant secondary porosity in the Late Devonian and Early Carboniferous would also make good targets.

在泥盆纪晚期和石炭纪早期产生大量次生孔隙的白云石也可能形成很好的油藏目标。

A light silver-white ductile bivalent metallic element; in pure form it burns with brilliant white flame; occurs naturally only in combination (as in magnesite and dolomite and carnallite and spinel and olivine).

轻而软的银白色二价金属元素，纯净状态下燃烧会发出明亮白光，仅天然存在于化合物中（如菱镁矿、白云石、光卤石、尖晶石、橄榄石）。

X-ray diffractometry analyses have shown that claystones are mainly composed of illite, calcite, dolomite, clinochlore, quartz, muscovite and pyrite.

对黏土岩的X射线粉晶衍射测试表明黏土岩的主要矿物成分为伊利石、方解石、白云石、绿泥石、石英、云母、黄铁矿等，具有弱膨胀性。

Optical microscope, scanning electron microscope and X-ray diffraction analysis have revealed that dawsonite mainly occur in the feldspar-rich sandstone and pyroclastic rocks, either as cements filling inter-grain pores as radical, bunchy, rosette, intricately trichoid, and platy collectives, or as replacement of feldspar and lithic grains with bunchy and paty shapes.

片钠铝石主要发育在油气储层或CO2气储层中富含长石的砂岩和火山碎屑岩中。在含片钠铝石砂岩和火山碎屑岩中，片钠铝石以放射状、束状、杂乱毛发状、球状和板状等集合体充填孔隙，或呈束状和板状交代长石和岩屑。片钠铝石及其共生的铁白云石都是最晚形成的自生矿物组合。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
