铁方解石

They crystallized in veins that are several centimeters in diameter, which were made up mainly of calcite, sodium feldspar albite, and iron sulfite pyrite.

它们体现在那些静脉直径几厘米，其中大部分为方解石，钠长石钠长石，黄铁矿和铁的亚硫酸盐。

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 carbonate cements, mainly consisting of ferroan calcite and ankerite, are telogenetic cements.

这样形成的碳酸盐胶结物为晚期胶结物，主要为含铁方解石和铁白云石。

The results showed that the trace elements were not anomalously enriched. Zn and Cu existed in sphalerite. Cr, Pb and Cd were adsorbed by clay minerals. Ba might exist in ankerite and calcite. Ni, Mo, Co and As mainly existed in pyrite. Be and Se were combined with organics. Many trace elements were difficult to volatilize. Because of high content and volatility, Pb and Zn, are harmful to environments; Zn and Pb separately exist in sphalerite and clay minerals, so it is easy to reduce their environmental damage by washing and processing of coal.

结果表明：研究的元素没有异常富集；Zn和Cu赋存于闪锌矿中，Cr、Pb和Cd被粘土矿物吸附，Ba可能赋存于铁白云石和方解石中，Ni、Mo、Co和As主要赋存于黄铁矿中，Be和Se以有机结合态存在；研究的元素大多不易挥发，但Zn和Pb易挥发，且含量较高，环境危害较大，Zn和Pb分别赋存于闪锌矿和粘土矿物中，可通过洗选脱除减小其危害。

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。

In this study, a set of parallel measurements of the specific surface area of calcite, quartz, smectites and marine hydrogenous ferromanganese crusts has been carried out.

以方解石粉体、石英粉体、蒙脱石等常见矿物材料和铁锰结壳为例，根据各类材料的比表面积测定数据，研究了探针气体种类、脱气温度和吸附平衡时间等测试条件的影响。

In the course of groundwater towards the center of the depression cone, not only the dissolution of calcite, dolomite and hematite, the precipitation of siderite and melanterite may occur, but also the cation exchange between Na+ and Ca2+, Fe oxidation- reduction of Fe may occur.

地下水在向降落漏斗中心区的径流过程中，不但发生了方解石、白云石和赤铁矿的溶解作用以及菱铁矿和水绿矾的沉淀作用，而且发生了Na+与Ca2+的交换、铁氧化-还原反应等一系列复杂的水-岩作用。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
