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 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。

Ankerite crystallization occurred at 320-370℃.

铁白云石的结晶作用发生在320~370℃。

Anhydrite, bassanite and ankerite founded in Bucha salt lake indicate that the source of salts is probably related to underground hydrothermal solution.

布查盐湖盐类沉积存在少量硬石青、半水石膏和铁白云石，表明布查盐湖的盐类物质来源很可能与地下热水作用有关。

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。

High salinity fluid inclusionscontaining daughter minerals have been found in quartz and ankerite of main mineralizingstages, Taibai and Baguamiao gold deposits of Shaanxi province, located in South Qinling.Both deposits occur in Devonian low-grade metamorphic rocks. Daughter minerals weredetected as pyrite, ankerite, halite and arsenopyrite by SEM/EDS and EPMA.

对赋存于南秦岭泥盆系浅变质碎屑岩中的陕西太白金矿、凤县八卦庙金矿主成矿阶段的石英和含铁白云石中的流体包裹体进行研究，发现局部富含高盐度、含子矿物的流体包裹体，通过光学显微镜、电子探针、扫描电镜/能谱发现子矿物主要为黄铁矿、铁白云石、石盐、毒砂及一些成分复杂的子矿物。

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。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
