方解石

Data obtained by thin-sections analysis, cathodoluminescence emission analysis and SEM/EDX show that carbonate cements seem to be the uppermost cements composed of ferroan sparry calcite and ankerite and are distributed mostly in the depth interval of 100 m below the unconformity, with their contents increasing with the depth.

通过薄片观察、阴极发光、扫描电镜/能谱分析，认为碳酸盐胶结物是研究区砂岩最主要的胶结物成分，其主要类型为方解石和铁白云石，垂向上含量随深度增加而增加，多集中分布在白垩系和侏罗系之间的不整合面之下约100 m的范围之内。

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。

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。

Paragenetic association I are composed of dissolved feldspar, quartz overgrowth and authigenetic kaolinite, This paragenetic association came into being acidic environment; Paragenetic association II include illite、albite、dissolved authigenetic quarze and kaolinite、dolomite、ankerite and ferrocalcite, the paragenetic association formed alkali environment; secondly, outcrop sandstones include paragenetic association III making up of dissolved feldspar、kaolinite、dickite and ironstone too, this paragenetic association came into being ground surface acidic environment.

成岩共生组合I由长石颗粒溶解、次生加大石英和自生高岭石组成，该组合形成于酸性成岩环境；成岩共生组合II由自生伊利石、自生钠长石、自生石英与高岭石溶解、白云石、铁白云石、铁方解石组成，该组合形成于碱性成岩环境；其次，露头砂岩还包括由长石颗粒溶解、高岭石、地开石、褐铁矿组成的第III种成岩共生组合，该组合形成于地表酸性成岩环境。

Small quantities of calcite was included inLuan Chuan nephrite and it has a good degree of crystallinity. X-ray powder diffraction and infrared spectrum show that the serpentine of Luan chuanconsists of fairly pure antigorite.

运用 X 射线和红外光谱对栾川软玉的分析表明，组成该地软玉的主要矿物成分为透闪石，其各项参数指标与标准透闪石十分接近，含有少量方解石，并且结晶度较好。

Clams as well as many other species of mollusk produce aragonite first and then transform the crystal to calcite.

我们要研究的文蛤及大部分的软体动物会先制造霰石，再将霰石转成方解石结晶。

Stalactites of calcite and a small aragonite formation appear as if in a magical backdrop.

钟乳石的方解石和一小的文石组成似乎像一不可思议的背景。

Calcite and aragonite are the two crystal forms of calcium carbonate, a property of minerals geologists call dimorphism.
